<div class="content-intro">
Founded in 2017, <a href="https://himalayas.app/companies/refurbed-com">refurbed</a> is Europe’s fastest-growing marketplace for refurbished products, active in 23 European countries and having surpassed €2Bn in GMV — all while being profitable. With beautiful headquarters in Vienna, we operate as a remote-first company and have been recognised as a Top DACH Employer by Kununu for four consecutive years.
Our mission is to make sustainable consumption the easy choice by enabling customers to buy products up to 40% cheaper while significantly reducing CO₂ emissions.
If you thrive in an environment that values momentum, ownership, and impact, you’ll feel at home here. We’re a fast-paced, high-performance team that works hard and challenges itself everyday. To enable this high-performance every team member enjoys full autonomy over their location (we’re remote-first).
</div>We are seeking an experienced Senior Backend Engineer (f/m/x) to join our App squad. In this role, you will be responsible for the design and implementation of scalable backend services that power <a href="https://himalayas.app/companies/refurbed-com">refurbed</a>'s mobile app and marketplace. Just as importantly, you understand how a native mobile app consumes those services - so you can guide backend decisions, your own and those of other squads, to fit the app's needs and constraints. You will work as part of a cross-functional product squad, collaborating closely with other engineers, product managers, designers, and business members to deliver robust, reliable, and high-performance solutions that enhance the experience of both our customers and our sellers.Our technology stack is built on proven, modern, and open-source technologies. On the backend, we primarily use Go, gRPC, PostgreSQL, Redis, and RabbitMQ, with Node.js / TypeScript powering a number of app-facing services. Our mobile app is built in React Native + Expo, and on the web frontend we leverage Vue.js, Alpine.js, and Tailwind CSS. Our infrastructure runs on Google Cloud Platform, orchestrated with Kubernetes, ensuring reliability and scalability at every layer.<h3>WHO YOU ARE:</h3><ul>
<li>You have 7+ years experience designing and building scalable backend services in a modern production environment</li>
<li>You have strong proficiency in Go and deep understanding of distributed systems and service-oriented architecture</li>
<li>You are comfortable with JavaScript/TypeScript, or confident you can pick up Node.js quickly - with strong Go fundamentals, we expect the rest to come easily. Existing Node.js experience is a plus.</li>
<li>You've worked on a team that builds and maintains a native mobile app. You don't need to write native code yourself, but you have real exposure to how mobile apps consume backend services and understand the constraints and caveats they introduce (API design for mobile, versioning and backwards compatibility, release cycles, latency, offline behaviour). You can spot when a backend decision won't fit the app and flag it early.</li>
<li>You are well-versed in SQL and relational database design</li>
<li>You have general knowledge of the frontend world, and are able to perform basic tasks in our frontend apps</li>
<li>You're a self-starter with strong ownership, initiative, and the ability to quickly learn and navigate complex systems</li>
<li>You're open-minded and communicate with clarity, directness, and respect</li>
<li>You value humility, are low-ego, and thrive in a collaborative, transparent culture</li>
<li>You have excellent English skills and you are based in a European time zone.</li>
<li>You are curious and eager to experiment with new and better ways of developing software, whether it's a new framework, the latest AI tool, or developing a new practice</li>
<li>A degree in Computer Science (or a related field) or equivalent work experience is desired as it provides a strong foundation for tackling the complex challenges we work on.</li>
<li>Bonus: you're comfortable operating beyond your own squad - reviewing designs and guiding other engineers whose work touches the mobile app. This role has room to grow into a broader technical leadership scope for the right person.</li>
</ul><h3>WHAT YOU'LL DO:</h3><ul>
<li>Design, build, and maintain our core APIs and backend services that power the mobile app and marketplace</li>
<li>Own the operations and the monitoring of production systems</li>
<li>Be the mobile-aware voice in backend decisions across squads: review designs and API changes, yours and other teams', to make sure they fit the needs and constraints of our mobile app, and flag caveats early</li>
<li>Integrate third-party systems and APIs into our platform</li>
<li>Own design and implementation of new features and services</li>
<li>Identify best practices and create/suggest standards to be used by whole engineering department</li>
<li>Documents and demonstrates solutions by developing documentation, flowcharts, layouts, diagrams, charts, code comments and clear code</li>
<li>Contribute to sustaining <a href="https://himalayas.app/companies/refurbed-com">refurbed</a> engineering culture by mentoring more junior colleagues and onboarding new joiners</li>
<li>Collaborate closely with other engineers, product managers, and business stakeholders to deliver high-quality solutions</li>
<li>Proactively offer insights and presents achievements and results in relevant meetings</li>
<li>Occasionally propagate your backend changes to frontend</li>
</ul><div class="content-conclusion">
<h3>WHY YOU WILL ENJOY WORKING WITH US:</h3>
<h3>Our Culture and Values:</h3>
<ul>
<li>Decisions should be made based on facts and not by hierarchy levels? We sure think so!</li>
<li>We embrace giving and receiving feedback, testing and welcoming new ideas, as well as sharing our knowledge across the company.</li>
<li>You fail sometimes? Well, so do we! We’re all just human, let’s learn from our mistakes to improve in the future!</li>
<li>No matter who you love, where you’re from, who you pray to, whether you pee sitting down or standing up – we are a bunch of talented people who enjoy spending our time making a difference!</li>
</ul>
<h3>Personal &amp; Professional Development:</h3>
<ul>
<li>You'll have access to a dedicated learning budget within your department to support your growth, whether it's courses, conferences, or other learning opportunities that matter to you.</li>
<li>We partner with Likeminded, offering you private sessions with experts for your personal growth and mental health.</li>
<li>We frequently host internal workshops, allowing our teams to further develop their skills in different areas and enhancing collaboration across departments.</li>
</ul>
<h3>Flexibility:</h3>
<ul>
<li>We care about a healthy work/life balance. We not only function and support a fully remote setting but also offer the possibility to work from our beautiful office in the vibrant heart of Vienna – we love dogs, so feel free to bring your furry little buddy too 😊</li>
<li>We trust you to do the best job, so we don't care so much when you do it – you are able to self-organize.</li>
<li>You will also be invited to take part in our office weeks, happening three times a year, where you will have the chance to work side by side with your colleagues and enjoy the team-building events and on-site workshops</li>

About The Role Atriabyte is hiring a Software Engineer to own mobile development across the company&apos;s products. The role is hands-on. You will be Atriabyte&apos;s mobile-first engineer, working alongside the technical co-founder and the six clinician founders who direct product decisions. The team is small &#x2014; six practising physicians and one full-time engineer today. The mobile surface area of Atriabyte&apos;s products is in active use across multiple Greek teaching hospitals; bringing it dedicated engineering attention is the point of this hire. Responsibilities <ul><li>Own the iOS and Android development of Atriabyte&apos;s mobile products end-to-end &#x2014; feature work, performance, releases, and crash-free quality.</li><li>Maintain a thoughtful pace of App Store and Play Store releases, including coordinating with hospital training programmes when their academic calendars demand it.</li><li>Translate clinical workflow requirements into mobile UX, working directly with the physician founders.</li><li>Contribute to the shared backend where mobile features require server changes.</li><li>Take occasional support and onboarding calls with clinician users. The current volume is small; the value of being close to users is large. </li></ul>Requirements <ul><li>Four or more years of professional engineering experience, including production iOS and Android work that has shipped to the App Store and Play Store.</li><li>Strong experience with .NET MAUI or Flutter or React Native &#x2014; Atriabyte will consider any of the three.

Senior Mobile Software Engineer

<div class="content-intro"><a href="https://himalayas.app/companies/airbnb">Airbnb</a> was born in 2007 when two hosts welcomed three guests to their San Francisco home, and has since grown to over 5 million hosts who have welcomed over 2 billion guest arrivals in almost every country across the globe. Every day, hosts offer unique stays and experiences that make it possible for guests to connect with communities in a more authentic way.</div><h3>The Community You Will Join: </h3>Guest &amp; Host Technology builds the end-to-end experience that connects people around the world: from the first search to the moment a trip becomes a memory. Because that experience lives natively on iOS and Android, with no cross-platform framework in between, we're looking for engineers who move fluidly across both platforms to keep architecture, performance, and product quality coherent everywhere our guests and hosts show up.<h3>The Difference You Will Make:</h3>We're looking for a Senior Software Engineer who can operate as a true dual-platform native engineer — someone with solid, current fluency in both iOS and Android. You'll own features end-to-end across both apps, and you'll be one of the people trusted to make architectural calls that need to hold up identically on Swift and Kotlin.You'll write production code on both platforms, and you'll also be expected to think beyond any single feature: flagging where our two native codebases are drifting apart, where a shared contract (like our GraphQL client layer) needs to evolve, and helping less experienced engineers ramp into dual-platform work.<h3>A Typical Day: </h3><ul>
<li>Design and ship features across our iOS (Swift) and Android (Kotlin) native codebases, often the same initiative, shipped in parallel on both platforms</li>
<li>Partner with design and product to translate one product spec into two platform-idiomatic implementations, rather than porting one platform's UI onto the other</li>
<li>Uphold architecture, performance, and app-size standards that apply equally to both platforms</li>
<li>Weigh in on shared client contracts (schema, logging, testing frameworks) consumed by both apps, and flag when a change would let the platforms drift apart</li>
<li>Help other engineers ramp into dual-platform work through pairing and code review</li>
<li>Participate in technical reviews and architecture discussions where your judgment is expected to span both platforms, not just one</li>
</ul><h3>Your Expertise:</h3><ul>
<li>6+ years of professional software engineering experience, with deep, current, hands-on expertise in both native iOS (Swift, UIKit/SwiftUI) and native Android (Kotlin, Jetpack Compose), not legacy exposure to one platform and active work on the other</li>
<li>A track record of independently shipping medium-to-large complexity features on either platform without ramp-up, and the ability to read, debug, and reason about the other platform's code even where you're less deep</li>
<li>Solid opinions on mobile architecture, backed by experience keeping two independent native codebases coherent at scale</li>
<li>Comfort owning a feature end-to-end with real ambiguity, and identifying when a decision needs to be escalated versus made independently</li>
<li>Experience partnering closely with design and product to translate ambiguous requirements into concrete, platform-appropriate implementations</li>
<li>A pragmatic view on cross-platform tooling — you understand why fully native matters here, and you're not looking for a role where you can lean on React Native or Flutter instead of doing the harder, more durable work</li>

You will work in an agile, parallel engineering environment with Claude Code woven into your daily workflow. You will work cross-functionally with backend and platform teams (consuming typed API contracts and the mobile CI pipeline) while enjoying high autonomy and low bureaucratic friction. Best of all, you will work primarily on a greenfield app, building a modern, clean client with no legacy debt. Core Responsibilities <ul><li>App Architecture: Design and build learner-facing features in React Native (Expo), from screens and navigation to state management, within a shared TypeScript layer also consumed by other client surfaces.</li><li>Core Tech Stack: Utilize React Native and TypeScript as your primary stack, building on Expo&#x2019;s managed workflow and the team&#x2019;s shared design-system package.</li><li>Mobile Delivery: Own the path from code to store: build configuration, versioning, code signing, and submission to the App Store and Google Play.</li><li>CI Integration: Trigger and consume the platform team&#x2019;s mobile CI/CD pipeline (EAS Build via GitHub Actions) to ship signed builds without owning the underlying infrastructure.</li><li>AI-Assisted Engineering: Actively integrate advanced tools like Claude Code into your daily GitHub and development workflow to maximize code quality and speed.</li><li>Clean Code Standards: Champion and apply best practices for type safety, testing, and accessibility across the app. </li></ul>Required Skills &amp; Qualifications <ul><li>Experience: 5+ years of professional mobile development experience, with a proven track record shipping production apps to real users &#x2014; React Native or native (iOS/Android).</li><li>Architecture &amp; Testing Discipline: Demonstrated architecture rigor (Clean Architecture, MVVM, or equivalent modular design) and testing discipline (automated unit, UI, or snapshot testing) in a production mobile codebase. This matters more to us than which specific framework you&apos;ve used it in.</li><li>Release Ownership: Hands-on experience owning mobile release engineering end to end: signed builds, app versioning, and store submission (TestFlight/Play internal tracks, review, staged rollout).</li><li>Modern Workflow: Proficiency with GitHub for version control, code reviews, and collaborating across parallel teams.</li><li>AI-Assisted Development: Comfort using AI coding tools (e.g. Claude Code) as a core part of your daily workflow. </li></ul>Nice to Have <ul><li>Strong, production-proven experience with React Native, ideally on Expo&apos;s managed workflow, including the New Architecture.</li><li>Working knowledge of iOS/Android code signing, shared design-system consumption, and client-side state management patterns.</li><li>Prior hands-on experience using AI coding tools in a production workflow (not just occasional use). </li></ul>What Makes This Role Great <ul><li>AI-Native by Default: We build with Claude (code generation, API design, code reviews, architectural documentation, and debugging). You get first-class AI tooling that takes the boilerplate off your plate, so your time goes to product craft, judgment, and the genuinely hard client problems.</li><li>Pure Greenfield: No legacy code, no technical debt, you own the design of the mobile experience for our global EdTech platform.</li><li>Infrastructure Support: A dedicated Platform Engineering team owns the underlying CI/CD pipeline and cloud infrastructure, so you focus on the app and the release craft that gets it to users.</li><li>100% Remote: Work from anywhere in Germany </li></ul>At Berlitz, connecting people across languages and cultures is at the heart of what we do. Our global workplace reflects the diverse world we serve, bringing together different backgrounds, experiences and perspectives. We create an inclusive environment where everyone has an equal opportunity to belong, contribute and grow. Ready to shape what&#x2019;s next? Join us and help build the future with us.

Software Engineer Intern (Summer 2027)

<div class="content-intro">Airbnb was born in 2007 when two hosts welcomed three guests to their San Francisco home, and has since grown to over 5 million hosts who have welcomed over 2 billion guest arrivals in almost every country across the globe. Every day, hosts offer unique stays and experiences that make it possible for guests to connect with communities in a more authentic way.</div>The Community You Will Join: 
Guest &amp; Host Technology builds the end-to-end experience that connects people around the world: from the first search to the moment a trip becomes a memory. Because that experience lives natively on iOS and Android, with no cross-platform framework in between, we're looking for engineers who move fluidly across both platforms to keep architecture, performance, and product quality coherent everywhere our guests and hosts show up.
&nbsp;
The Difference You Will Make:
We're looking for a Senior Software Engineer who can operate as a true dual-platform native engineer — someone with solid, current fluency in both iOS and Android. You'll own features end-to-end across both apps, and you'll be one of the people trusted to make architectural calls that need to hold up identically on Swift and Kotlin.
You'll write production code on both platforms, and you'll also be expected to think beyond any single feature: flagging where our two native codebases are drifting apart, where a shared contract (like our GraphQL client layer) needs to evolve, and helping less experienced engineers ramp into dual-platform work.
&nbsp;
A Typical Day:&nbsp;
<ul>
<li>Design and ship features across our iOS (Swift) and Android (Kotlin) native codebases, often the same initiative, shipped in parallel on both platforms</li>
<li>Partner with design and product to translate one product spec into two platform-idiomatic implementations, rather than porting one platform's UI onto the other</li>
<li>Uphold architecture, performance, and app-size standards that apply equally to both platforms</li>
<li>Weigh in on shared client contracts (schema, logging, testing frameworks) consumed by both apps, and flag when a change would let the platforms drift apart</li>
<li>Help other engineers ramp into dual-platform work through pairing and code review</li>
<li>Participate in technical reviews and architecture discussions where your judgment is expected to span both platforms, not just one</li>
</ul>
 Your Expertise:
<ul>
<li>6+ years of professional software engineering experience, with deep, current, hands-on expertise in both native iOS (Swift, UIKit/SwiftUI) and native Android (Kotlin, Jetpack Compose), not legacy exposure to one platform and active work on the other</li>
<li>A track record of independently shipping medium-to-large complexity features on either platform without ramp-up, and the ability to read, debug, and reason about the other platform's code even where you're less deep</li>
<li>Solid opinions on mobile architecture, backed by experience keeping two independent native codebases coherent at scale</li>
<li>Comfort owning a feature end-to-end with real ambiguity, and identifying when a decision needs to be escalated versus made independently</li>
<li>Experience partnering closely with design and product to translate ambiguous requirements into concrete, platform-appropriate implementations</li>
<li>A pragmatic view on cross-platform tooling — you understand why fully native matters here, and you're not looking for a role where you can lean on React Native or Flutter instead of doing the harder, more durable work</li>
</ul>
&nbsp;
Your Location:
This position is US - Remote Eligible. The role may include occasional work at an Airbnb office or attendance at offsites, as agreed to with your manager. While the position is Remote Eligible, you must live in a state where Airbnb, Inc. has a registered entity. <a style="color: #000000;" href="https://careers.airbnb.com/">Click here for the up-to-date list of excluded states. This list is continuously evolving, so please check back with us if the state you live in is on the exclusion list. </a>If your position is employed by another Airbnb entity, your recruiter will inform you what states you are eligible to work from.
&nbsp;
Our Commitment To Inclusion &amp; Belonging:
Airbnb is committed to working with the broadest talent pool possible. We believe diverse ideas foster innovation and engagement, and allow us to attract creatively-led people, and to develop the best products, services and solutions. All qualified individuals are encouraged to apply.
We strive to also provide a disability inclusive application and interview process. If you are a candidate with a disability and require reasonable accommodation in order to submit an application, please contact us at: <a style="color: #000000;" href="mailto:reasonableaccommodations@airbnb.com">reasonableaccommodations@airbnb.com</a>. Please include your full name, the role you’re applying for and the accommodation necessary to assist you with the recruiting process.&nbsp;
We ask that you only reach out to us if you are a candidate whose disability prevents you from being able to complete our online application.
&nbsp;
Equal Employment Opportunity:
Airbnb values diversity &amp; belonging and is proud to be an Equal Employment Opportunity employer. All individuals seeking employment at Airbnb are considered without regard to race, color, religion, national origin, age, gender, sex, marital status, ancestry, physical or mental disability, veteran status, gender identity, gender expression, sexual orientation, or any other legally protected characteristic.<div class="content-pay-transparency"><div class="pay-input"><div class="description">How We'll Take Care of You:
Our job titles may span more than one career level. The actual base pay is dependent upon many factors, such as: training, transferable skills, work experience, business needs and market demands. The base pay range is subject to change and may be modified in the future. This role may also be eligible for bonus, equity, benefits, and Employee Travel Credits. &nbsp;</div><div class="title">Pay Range</div><div class="pay-range">$196,000&mdash;$227,000 USD</div></div></div><div class="content-conclusion">&nbsp;
Reasonable Accommodations: We are committed to providing reasonable accommodations throughout the recruitment process for applicants with disabilities. If you need assistance, or an accommodation, please let your recruiter know once you are contacted about a role.
A Note on Recruiting Scams: Scammers sometimes pose as Airbnb recruiters to get money or personal information from candidates. A few things that will always be true for Airbnb’s hiring process: our open roles are posted on Airbnb’s Career’s Page at careers.airbnb.com, and our recruiters correspond only from @<a href="http://airbnb.com">airbnb.com</a> or @<a href="http://ext.airbnb.com">ext.airbnb.com</a> email addresses. Our recruiters will never ask for your Social Security number, bank account details, passport, or payment app information while you are interviewing.&nbsp; We’ll also never ask you to pay a fee, send money, deposit or cash a check, or purchase work-related equipment (such as a company laptop) during the interview process. We encourage candidates to remain vigilant of these recruiting scams and not share sensitive information if you do not believe an individual is actually affiliated with Airbnb.

This is not about hiring someone who can simply claim they &quot;use AI&quot;. We&#x2019;re looking for an experienced engineer who has led major technology change before, whether that has been cloud adoption, microservices, platform modernisation or new engineering operating models, and is now back at the coal face experimenting seriously with AI-native and agentic software development. The challengeThe business currently maintains separate applications across web, iOS and Android.The ambition is to establish a modern multi-platform architecture and test whether a senior engineer + agentic tooling can materially change the speed and economics of rebuilding the product. The initial 8-week production pilot will involve:&#x2022; Defining the target multi-platform architecture&#x2022; Rebuilding a valuable end-to-end customer journey&#x2022; Using AI agents throughout the engineering lifecycle, with humans providing architecture, intent and judgement&#x2022; Shipping to production early and incrementally&#x2022; Challenging whether incremental replacement or a larger rewrite is the right approach&#x2022; Improving the wider engineering foundations as constraints emerge&#x2022; Working closely with an existing Tech Lead and transferring capability into the team Who we&#x2019;re looking forYou&#x2019;ll likely be operating at Staff / Principal Engineer level and able to combine deep engineering expertise with product and commercial thinking.You should be able to explain not only what you built, but why it mattered to the customer or business. We&#x2019;re particularly interested in people who have:&#x2022; Led meaningful engineering or architectural transformation before&#x2022; Strong software engineering and system architecture fundamentals&#x2022; Built customer-facing products, ideally across mobile/web environments&#x2022; Experience influencing technical direction beyond their own individual contribution&#x2022; A pragmatic approach to modernising legacy systems&#x2022; Genuine hands-on fluency with tools such as Claude Code, Codex, Cursor or similar agentic development workflows&#x2022; Strong opinions on how AI changes software delivery, backed up by practical experimentation&#x2022; The gravitas to challenge senior stakeholders and shape how an engineering organisation works. You do not need to have spent years calling yourself an &quot;AI Engineer&quot;. The priority is an excellent engineer who understands the potential of agentic software development and is actively pushing what these tools can do. Interested, or know somebody operating at this level? Drop me a message.

About the Role: We&apos;re not hiring for a specific layer of the stack &#x2014; we&apos;re hiring for ownership. As a Senior Product Engineer, you&apos;ll join a small, autonomous &quot;mini-startup&quot; squad that owns a product domain end-to-end, from first prototype to production. You&apos;ll use AI agents daily to move fast across the stack, so you can focus on what matters: solving real customer problems and shipping measurable outcomes.Real depth in one layer of our stack &#x2014; mobile (Kotlin/KMP, or native iOS/Android), backend (Java/Spring Boot), or frontend (Angular) &#x2014; is what we screen for; the ability to work confidently in the others, with AI leverage, is what makes you a fit. We&apos;re actively growing our mobile bench right now, so a strong native iOS or Android background is very welcome even without prior Kotlin Multiplatform experience. What You&apos;ll Do<ul><li>Own the Product Journey: Operate with a true builder mindset.
