Job Summary
In this role, you'll develop robust applications using React, Next.js, TypeScript, and Node.js, design AI-native user interfaces, and make decisions on architecture, performance, and data structures for both UI and APIs.
Job Technologies
Your role in the team
- You stopped coding. And that's exactly why we want you.
- Software is changing. AI agents are changing how people interact with products - and we're building for what comes next.
- Join our UI Engineering team and build production-grade products at the intersection of AI, engineering, UX and product.
- You'll shape not just how our products look and work, but how people will interact with them in the future.
- Sei ein Ingenieur. Denke wie ein Produktentwickler.
- Own the experience. Own the technology. Build what comes next.
- Build production-grade applications with React, Next.js, TypeScript and Node.js - from UI to APIs and services.
- Design AI-native experiences: conversational UIs, agent-driven workflows and natural-language interactions.
- Use AI as an engineering multiplier. Explore, prototype, implement, debug and test faster - while staying firmly in control of architecture, quality and the final result.
- Understand the customer, the business and the problem before deciding what to build.
- Challenge assumptions, simplify complexity and turn ambiguity into products people actually use.
- Shape scalable architectures, APIs and data structures across the stack.
- Collaborate with Product, UX/UI, and Engineering to make better decisions together.
- Raise the bar for testing, performance, maintainability and engineering quality.
- You're not here to turn tickets into components. You're here to decide what should be built - and then build it.

Our expectations of you
Qualifications
- Think and work AI-native. You already use AI as part of your engineering workflow and have developed your own approach to getting from idea to production-ready code.
- Bonus: AWS, Jenkins, Grafana, Graylog, Confluence, Jira, shell scripting.
- Master React, Next.js, TypeScript and Node.js and understand modern web architectures.
- Treffen Sie selbstbewusste technische Entscheidungen in Bezug auf Architektur, Leistung, Skalierbarkeit und Wartbarkeit.
- Work confidently with APIs and data: REST, database design and SQL; GraphQL is a plus.
- Think beyond the code. You're curious about customers, products and the business and use that context to make better technical decisions.
- Übernehmen Sie Verantwortung für Ergebnisse, nicht nur für die Umsetzung.
Experience
- Bring 5+ years of hands-on full-stack JavaScript experience and a strong track record of shipping real applications.
- Build and test production-grade software. Hands-on experience with Jest, Vitest or Node.js testing is essential.
- Stay curious about what's next. Experience with AI-first interfaces, agent workflows or natural-language products is a plus.

What we offer
- Ownership over tickets: You're trusted with real responsibility, not just tasks.
- No unnecessary bureaucracy, no micromanagement - we rely on you to take things forward.
- Build Talk: We test what works - not what sounds good. Fail fast, learn faster.
- Hohe Standards, geringes Ego: Wir nehmen unsere Arbeit ernst, aber nicht uns selbst.
- Direct feedback, honest collaboration, no drama.
- Stay sharp: Hackathons, conferences, community - we invest in your growth and keep you at the cutting edge.
- And yes - the fundamentals are covered too: 30 days of vacation + Dec 24 & 31 off, Smart Fridays (4 days week possible), mobility (Germany ticket & JobRad), sports & health offerings, mental health support, corporate benefits, RTL+ access, and more.
- Your CV is just the starting point.
- What matters more to us than your resume: a portfolio, a side project, a demo repo - anything that shows you don't just talk about code, you ship it. Production-ready. Thought through. Done.
