Jobbeschreibung

At smartclip, we're not just building software — we're shaping the future of video and audio advertising tech across Europe. If you've got strong opinions about clean code, love writing Typescript more than emails, and think React is more than just a buzzword, then we might be your kind of people.

We’re on the lookout for a Senior Full Stack Engineer (f / m / d) who enjoys working across the stack — from API design to front-end polish — and isn’t afraid of a little DevOps along the way.

Activities

• Own what you build : from database schema to frontend UI, you ship it, you run it.
• Turn product ideas into scalable systems and elegant UIs using Node.js + React (all written in lovely TypeScript, of course).
• Review code like you mean it. Teach, mentor, challenge — and learn from — your fellow devs.
• Break down business requirements into clean, maintainable logic — you know, the kind of code that future-you will

thank you for.

• Write robust unit / integration tests using tools like Jest , Playwright , or your testing weapon of choice.
• Spot bottlenecks, squash bugs, and continuously improve performance and developer experience.
• Be part of a team that

actually does pair programming, architecture talks, and code design discussions.

Requirements

• You speak fluent TypeScript and know how to make Node.js APIs and React frontends play nicely together.
• You've spent at least 5 years in production-grade projects , and you have battle scars (and Git commits) to prove it.
• Databases don’t scare you. You write solid SQL and design schemas with purpose.
• TDD isn’t a philosophy — it’s how you roll. You’re the type who won’t sleep well if your coverage drops.
• You understand design patterns , reusable code, and when to be pragmatic over academic.

Team

We build with the tools we love (and we love good tools) : TypeScript, Node.js, React, Python, SQL, Scala, Java, Docker, Kubernetes, AWS, GCP, C++, GitHub Copilot, and the occasional caffeine-fueled whiteboard sketch. And we’re not afraid to throw something out if there’s a better way.
