Life360 delivers peace of mind and enhances everyday family life with seamless coordination for all the moments that matter, big and small. By continuing to innovate and deliver for our customers, we have become a household name and the must-have mobile-based membership for families (and those friends who are basically family). Life360 has more than 500 (and growing!) remote-first employees. For more information, please visit life360.com. Life360 is a Remote First company, which means a remote work environment will be the primary experience for all employees. All positions, unless otherwise specified, can be performed remotely (within the US and Canada) regardless of any specified location above. We are AI Native We are building an AI native company where AI is an integral part of how we build and operate. AI tool usage during interviews varies by role. You may be asked to demonstrate proficiency with AI tools, discuss how you leverage AI, or complete interview exercises without AI assistance. Your Recruiter will provide clear guidance as you move through the interview process. Undisclosed use of AI not previously discussed with or approved by your Recruiter may impact your candidacy. About The Team The Revenue Experimentation team (Direct Revenue org) is the engine behind how we grow and monetize Life360 responsibly. We design, ship, and analyze high-velocity experiments across ads, subscriptions, and one-time purchases &#x2014; pricing, paywalls, ad placement and mediation, upsell and upgrade flows &#x2014; so every monetization decision is grounded in evidence, not instinct. Our work directly shapes the revenue behind nearly 100 million members. We are a product-minded, AI-Native engineering team. AI isn&apos;t just a tool we use &#x2014; it&apos;s how we work. We treat it as a first-class collaborator at every stage: ideation, coding, testing, review, and iteration. We ship faster and go deeper because of it, and we&apos;re looking for someone who wants to help define what that looks like at scale. About The Job Life360 is hiring an AI-Native Senior Software Engineer II &#x2014; a builder who thinks natively in AI tooling and takes real ownership of outcomes, not just tickets. You&apos;ll be central to how the Revenue Experimentation team designs and ships growth and monetization experiments across the Life360 app. You&apos;ll take a hypothesis &#x2014; sometimes a fully-specced brief, sometimes a rough idea from a Slack thread or a data science finding &#x2014; and turn it into a running, safely-instrumented experiment. You default to shipping and iterating rather than waiting for a perfect spec or explicit permission. You&apos;ll run experiments confidently at a high clip. This role is Android-first, but candidates who treat platform boundaries as fluid &#x2014; willing to build across iOS, web, or backend when an experiment calls for it &#x2014; are exactly who we&apos;re looking for. In your first year, success looks like owning end-to-end delivery across multiple concurrent experiment surfaces, and having at least one AI-native workflow you introduced adopted beyond this team. For candidates based in the US, the salary range for this position is $118,500 to $216,500 USD. For candidates based out of Canada, the salary range for this position is 171,500 to 201,000 CAD. Note: Please be aware that the job title for positions in Canada will be &quot;Developer&quot; in lieu of &quot;Engineer.&quot; We take into consideration an individual&apos;s background, job-related knowledge, skills, and experience in determining final salary. Base pay may also vary based on geographic location, with US work locations falling into one of three geographic tiers. Total compensation is inclusive of equity compensation in the form of Restricted Stock Units (RSUs), as well as a comprehensive benefits package, including medical, dental, vision, financial, and other benefits. What You&#x2019;ll Do <ul><li>Design and build high-quality Android growth and monetization features and experiments &#x2014; subscription paywalls and pricing tests, ad placement and mediation experiments, one-time purchase (IAP) flows, and upsell/upgrade surfaces &#x2014; running dozens of concurrent tests across the Life360 app.</li><li>Partner with product, design, data science, and analytics to translate hypotheses into shippable experiments, and turn results into the next decision &#x2014; pushing back when a hypothesis or plan doesn&apos;t hold up.</li><li>Work with AI (Claude Code or equivalent) as a first-class collaborator &#x2014; your primary workflow involves orchestrating agents to create specs, generate code and tests, verify results, and perform reviews.</li><li>Instrument experiments accurately &#x2014; exposure logging and analytics &#x2014; so the results downstream teams rely on are trustworthy.</li><li>Ship polished, performant, reliable Android experiences to tens of millions of users, with strong attention to startup time, memory, battery, ANR, and crash-free rates.</li><li>Own staged rollouts end-to-end &#x2014; ramp exposure, monitor guardrails, and make the call to hold, roll back, or scale to 100%.</li><li>Help define and codify AI-native Android engineering practices for the team, establishing playbooks the broader mobile org can adopt.</li><li>Contribute to architectural decisions, code reviews, and a culture of craft and continuous improvement on the Android codebase.</li><li>Participate in on-call rotation and incident response for mobile experiments and releases.</li><li>Mentor other engineers and contribute to team processes and technical standards. </li></ul>What We&#x2019;re Looking For Technical Foundation <ul><li>6+ years of Android software engineering experience shipping production apps at consumer scale.</li><li>At least 1 year of hands-on experience prompting, evaluating, and building with LLMs.</li><li>Strong proficiency with Kotlin and Jetpack Compose (and the Android View system); deep familiarity with the modern Android toolchain (Android Studio, Kotlin Coroutines, Flow).</li><li>Experience with Android architecture patterns (MVVM, MVI, Clean Architecture, Jetpack/ViewModel/Navigation, Hilt or Dagger) in a large, multi-team codebase.</li><li>Comfort with mobile experimentation concepts: feature flagging, A/B testing, exposure logging, holdouts, and guardrail metrics.</li><li>Solid grounding in mobile performance, memory, battery, ANR, and crash diagnostics (Android Studio Profiler, Perfetto/Systrace, Macrobenchmark, Crashlytics or equivalent).</li><li>Experience with CI/CD for Android (Gradle, Fastlane, GitHub Actions, Bitrise, or similar) and modular build systems.</li><li>Expertise with agentic workflows, prompt engineering, context-window management, and MCP/function calling &#x2014; you understand the research-plan-implement cycle but don&apos;t outsource thinking to agents.</li><li>Bachelor&apos;s degree in a technical field, or equivalent experience. </li></ul>What Matters Most To Us <ul><li>Agency &#x2014; You don&apos;t wait to be told what to do.

You are accountable for everything you ship.</li><li>Velocity &#x2014; We expect senior engineers who use AI well to operate with meaningful leverage, taking on problems that would otherwise require a larger team.</li><li>Team leadership &#x2014; You share what works, automate prompting strategies others can build on, and help teammates earlier in their AI workflow adoption get up to speed.</li><li>Continuous learning &#x2014; The tooling changes fast. You stay current and bring recommendations to the team when something would meaningfully improve how we work. </li></ul>Our Benefits <ul><li>Medical, dental, vision, life and disability insurance plans (100% paid for US employees).

Software Developer (Product Engineer)

<a href="https://jobicy.com/company/maintainx" target="_blank" rel="noopener">MaintainX</a> is a leading mobile-first work execution platform for industrial and frontline teams. More than 13,000 customers, including Duracell, McDonald's, Shell, DHL and Volvo, use MaintainX to cut unplanned downtime and run better operations, across 13.9 million managed assets and 79.5 million completed work orders.
In August 2026 MaintainX became part of Autodesk, joining <a href="https://adsknews.autodesk.com/en/views/inside-autodesk-operations-solutions/" rel="nofollow ugc noopener" target="_blank">Autodesk Operations Solutions</a>, the organization unifying Autodesk's operations platform alongside Tandem, FlexSim and Fusion Operations. Autodesk's strategy is to converge design, make and operate into one continuous lifecycle: design an asset, build it, run it, then feed what you learn running it back into the next design. Autodesk had design and make. Operate is the phase that tells you what actually happened, and it is ours.
We're growing fast and hiring the Engineering talent to match.
You'd be joining our Mobile team within the Platform Engineering division. We treat our internal developer platform as a real product, with internal customers (our feature teams, 150+ developers) and adoption metrics.The mission for this role: make it dramatically faster and safer to ship mobile features at MaintainX.
Today, feature teams reinvent patterns, fight with build infrastructure, and ship slower than they should because the foundations underneath them are inconsistent. We want a mobile foundation where feature teams stop thinking about CI, release trains, shared components, and observability, they just build features.
What you’ll do: 
<ul>
<li>
Design, build, and maintain mobile React Native foundations and tooling powering our internal developer platform.
</li>
<li>
Bring AI native workflows into your daily work and into the platform.
</li>
<li>
Raise engineering excellence standards.
</li>
<li>
Lead to the consolidation and evolution of platform primitives: SDKs, CI pipelines, build tools, local development golden paths. 
</li>
<li>
Collaborate with other platform teams and product development teams on defining and adopting the internal developer platform.

The Staff Mobile Engineer is a unique and vital role within Madison Reed, owning the mobile experience that has become the primary daily touchpoint for our customers. This role involves architecting and leading the development of our React Native application across iOS and Android, driving the technical strategy for mobile, and contributing to the organization&apos;s long-term architectural vision. Working in a cross-functional, agile environment, the engineer collaborates with teammates, product owners, designers, and stakeholders to ship a premium, native-feeling experience for our full e-commerce, appointment, and membership business &#x2014; while mentoring engineers at all levels and fostering a culture of innovation, collaboration, and excellence. This is also an AI-forward role. We expect our Staff Mobile Engineer to both build AI-powered experiences into the app and to have fundamentally changed how they build by working alongside frontier agentic coding tools &#x2014; while retaining the deep technical skepticism required to audit, verify, and own everything that ships. The base range for this contract position is between $185k-$190k with expectation of 40 hours a week. At Madison Reed, we aim to pay competitively.

We already maintain native modules for Live Activities, biometric authentication, beacons, AR virtual try-on, and payments &#x2014; you&apos;ll extend and harden these.</li><li>Champion mobile UX and performance. Obsess over the details that make an app feel premium and native: frame rates, navigation transitions, list rendering, keyboard handling, and the accessibility standards required to support a diverse customer base.</li><li>Own reliability in the wild. Treat CI/CD, crash monitoring, analytics, and App Store / Play Store release management as a fundamental part of the job &#x2014; not an afterthought. Set a high bar through monitoring, error tracking, and optimization.</li><li>Take ownership of large, ambiguous initiatives and break them into actionable workstreams. Lead efforts to refactor and optimize large areas of the codebase, ensuring alignment with business goals and long-term scalability.</li><li>Mentor and raise the bar. Establish patterns for code reuse, elevate the engineers around you through rigorous code review and testing practices, and foster a culture of technical excellence and knowledge sharing.</li><li>Collaborate with product and leadership to align technical solutions with business priorities, shaping both what gets built and how it gets built. </li></ul>What We&apos;re Looking For <ul><li>8+ years of professional software engineering experience, with deep, specialized focus on React Native and Expo.</li><li>A proven track record of building, shipping, and maintaining complex, data-heavy mobile applications in production at scale.</li><li>Expo and mobile infrastructure expertise.

You understand the React render cycle on mobile, know how to prevent UI-thread blocking, optimize list rendering, and orchestrate complex asynchronous data fetching. Strong command of TypeScript, navigation patterns, and platform-specific considerations.</li><li>Full lifecycle ownership. You build things that run reliably in production, not just pass review &#x2014; owning the CI/CD pipeline, crash rates, and your app&apos;s behavior in the real world.</li><li>Your workflow has been altered by AI. You are already using frontier agentic coding tools (e.g. Claude Code, Codex) to build faster, and can describe specific ways they have structurally changed how you work &#x2014; while retaining the skepticism to audit, verify, and fully own their output.</li><li>Demonstrated technical leadership. A track record of setting technical direction, designing scalable and maintainable architecture, and measurably leveling up the engineers around you.</li><li>A high-ownership mindset with a bias toward action, comfort operating in ambiguity, and strong product intuition.</li><li>Exceptional communication and collaboration skills, with low ego and high standards. </li></ul>Bonus Points <ul><li>Experience integrating LLMs, AI agents, or ML-powered features into a production mobile app.</li><li>Native iOS (Swift/Objective-C) or Android (Kotlin/Java) experience for when we need to drop into native code &#x2014; we maintain custom modules including Live Activities and biometric auth.</li><li>Background in e-commerce, subscriptions/memberships, payments, or appointment/booking systems.</li><li>Experience with AR / virtual try-on, location services, or push/lifecycle messaging.</li><li>Open-source contributions, or apps you&apos;ve built and shipped to the world yourself. </li></ul>Big On Benefits The Perks?

How we work <ul><li>High-velocity: Rapid experimentation, lean autonomous teams, and minimal bureaucracy.</li><li>Impact not job titles: We don&#x2019;t have job titles.

The team is small, agent-first and sits apart from the main org, with very fast CI, so ideas often ship the same or next day. Today, one engineer runs the whole iOS app alone. We&#x2019;re looking for a Mobile Engineer to own ElevenMusic across iOS and Android, and to make mobile a driver of the product rather than a downstream port of web features. You&#x2019;ll build for musicians and creatives, think in systems as well as screens, and work with high autonomy and a high bar for taste. Requirements <ul><li>Shipped a well-designed, production mobile app that real users love, and can show us what you owned.</li><li>Strong systems thinking across mobile and backend. We&#x2019;re framework-agnostic (React Native, Swift or Kotlin), but expect you to work across iOS and Android.</li><li>Exceptional product taste and a clear view on what makes a mobile experience great.</li><li>Highly self-directed: you turn loose directions into shipped work and own the outcome. </li></ul>Bonus: musical interest or intuition. Open-source or GitHub contributions. Location This role is remote-first, so it can be executed from anywhere in Europe and the US East Coast, with the ability to operate in GMT-5 to GMT+1 timezones required. If you prefer, you can work from our offices in London, New York, Warsaw, and Amsterdam. We are an equal opportunity employer and do not discriminate on the basis of race, religion, national origin, gender, sexual orientation, age, veteran status, disability or other legally protected statuses.

<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>

Sviluppatore front-end

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. Native Swift / Kotlin alone is not the right fit for this role.</li><li>Comfortable working across the mobile / backend boundary when a feature requires it.</li><li>Fluent Greek required &#x2014; for occasional clinician support calls and to keep written communication with users idiomatic.</li><li>Experience working in regulated environments (healthcare, financial, or similar) is a plus, not a requirement. </li></ul>Compensation and terms <ul><li>Base compensation: &#x20AC;1,600 / month, gross. This is candidly below market for senior European engineers, and Atriabyte will not negotiate it upward. Equity and the nature of the work carry the rest of the offer.</li><li>Meaningful equity participation as one of the first engineering hires.</li><li>Fully remote within the EU. Greek-resident or Greek-diaspora candidates only, given the language requirement.</li><li>Direct involvement in roadmap decisions. With a team this small, every engineer is in the room when decisions are made.</li><li>A team where the founders are clinicians, decisions are made on first principles, and there is no layer of management between you and the work.</li></ul>
