We are looking for a Senior Golang Developer (Fullstack, Backend-Heavy) to join one of our high-growth client teams as a core software architect. In this role, you will be responsible for designing and scaling high-performance, low-latency microservices using Go, while also stepping into the frontend layer to build clean, responsive user interfaces.

You will be the engineering driver behind the client’s product scaling efforts, moving beyond basic CRUD applications to solve complex data ingestion, distributed systems concurrency, and real-time state challenges. This is a role for a systems-thinking developer who loves the speed and simplicity of Go but understands how to deliver a complete, polished end-to-end user experience.

*   Proven track record of building microservices using HTTP frameworks (Gin, Echo, Chi) or gRPC / Protocol Buffers.
*   Solid experience with modern frontend development using TypeScript and React.js or Vue.js for consuming complex API contracts.
*   Advanced knowledge of relational databases (PostgreSQL preferred) along with high-performance query optimization and connection pooling.
*   Experience managing message brokers or event streaming platforms like Kafka, RabbitMQ, or Redis.
*   Hands-on experience containerizing services with Docker and orchestrating deployments via Kubernetes inside cloud environments (AWS, Azure, or GCP).
*   A strict testing mindset, implementing robust unit testing patterns (go test, test suites) and automated integration tests.
*   Located in CET timezone (+/- 3 hours), we are unable to consider applications from candidates in other time zones.

**Nice-to-have:**

*   Experience with Infrastructure as Code (Terraform or Bicep).
*   Understanding of eBPF, WebAssembly (Wasm), or writing low-level networking tools in Go.
*   Familiarity with frontend build tools like Vite or Webpack.
*   Background in domain-driven design (DDD) and clean architecture.

**Responsibilities:**

*   Design, implement, and maintain highly performant Go backends along with their corresponding frontend interfaces.
*   Profile and tune Go applications (using pprof, flame graphs) to ensure minimal memory footprints and ultra-low latency.
*   Design structured, self-documenting RESTful or gRPC APIs that allow seamless communication between microservices and the client interface.
*   Conduct constructive peer code reviews, championing clean code principles, SOLID patterns, and idiomatic Go architectures.
*   Work alongside DevOps engineers to build and maintain automated testing and deployment pipelines.

**Main technologies:** Python, NodeJS, React, TypeScript, JavaScript, AWS

Clipster helps brands scale organic distribution through creators, with clear tracking, simple execution, and payouts tied to actual views.

After running campaigns manually, we built a platform to make the model scalable.

Since launching in early 2025, we've grown to 100,000+ creators, paid out $5M+, acquired 120+ clients, and run campaigns for names like Telegram, UFC, Universal Music Group, Elton John, Ed Sheeran, Playboi Carti, and Kendrick Lamar.

Our growth has been 100% organic.

*   Now we need someone to make sure the right people hear about what we're building.

The role

We are looking for a Backend-Heavy Senior Engineer who isn't afraid to touch the full stack. While your primary domain will be our Golang services and distributed architecture, you are a "Product Engineer" at heart — meaning you understand the "why" behind the code and can jump into the React/Next.js frontend whenever it's the shortest path to delivering value.

The mindset we hire for

*   Intensity & Grit — You run toward hard problems and stay until they are solved.
*   Ambitious Simplification — You have the intelligence to solve complex problems and the wisdom to choose the simplest solution.
*   Ownership & Mission Alignment — You don't "close tickets"; you ship outcomes. You care about the creator economy as much as we do.
*   AI Readiness — You leverage modern tools to multiply your output and keep us at the cutting edge.
*   Humility & Collaboration — You are a high-bandwidth communicator who mentors others and leaves your ego at the door.

Your technical toolkit

*   Core Backend — 5+ years of experience, with at least 3+ years of mastery in Golang. Comfortable with high-performance distributed systems.
*   Fullstack Versatility — Backend is your home, but you have the skills to navigate and contribute to a React/Next.js frontend.
*   Infrastructure & Data — Deep knowledge of PostgreSQL, Redis, and ideally GCP.
*   Architectural Mindset — You move seamlessly from system design to shipping production-ready code. Clean code, test coverage, and documentation are your tools for maintaining velocity.

Bonus points

*   Experience with payment systems (we handle around $1M in monthly payouts).
*   Event-driven architectures and real-time data processing.

Why Clipster

*   Total ownership — Join a lean tech team of fewer than 15 people. What you build today, millions will use tomorrow.
*   Remote & async — Work where you are most effective. We only ask for availability during our core hours (10am – 2pm UTC+2).
*   Zero bureaucracy — No endless meetings. We value documentation, Slack, and Loom for high-bandwidth, low-noise collaboration.

Our culture

We've always strived to build a company we enjoy working for. Here's what that means for us:

*   High-quality software. Clean code, polished features, software we're proud to ship. Everyone here cares deeply about their work.
*   Low hierarchy, high collaboration. Open communication, zero red tape, and easy access to everyone in the team. We support, mentor, and uplift each other.
*   Small team, high independence and ownership. 12 people in the tech team, so what you do matters. Lots of space to grow in responsibility and ownership.
*   Fully remote, flexible, async. Work when and where you're most effective. Our core hours are 10am - 2pm UTC+2.

Next steps

*   Discovery call — a brief chat with our recruiter.
*   Pair programming — a hands-on session with one of our engineers.
*   System design — a discussion about an architectural problem, based on our day-to-day problems.
*   Engineering excellence discussion.
*   Final meet — chat with our Founder and PM to talk mission and values.
