UI Engineer (f/m/d) - AI

We use AI to accelerate – not to replace thinking.
We design the system, steer the output, and take responsibility for what we ship.
Fast where it makes sense. Careful where it matters.

You stopped coding. And that’s exactly why we want you.

• Own the UI layer – from vision to production. Don’t just write components – shape how our product feels and behaves.
• Architect and build production-grade frontends for AI agent products using React and Next.js.
• Design interaction patterns for natural language and agent-driven interfaces – create what doesn’t exist yet.
• Work closely on UX and product thinking – understand the “why” behind what you build.
• Translate business requirements into clear, scalable product decisions.
• Establish frontend best practices: architecture, testing, and quality standards.
• Move fast with AI as a tool – and ensure everything you ship meets a production-ready standard.

• Bring deep experience shipping real applications. Make confident decisions on architecture, performance, and scalability.
• Embrace an AI-native workflow. Use AI to accelerate your work, but stay in control of quality, structure, and output.
• Develop and apply your own system for building production-ready code with AI.
• Think in products, not just in code. Understand context, challenge assumptions, and take ownership of outcomes.
• Maintain a high quality bar. Write tests, review thoroughly, and keep architecture clean – even when moving fast.
• Optional: Work with AI-first interfaces. Build conversational UIs, agent-driven experiences, or natural language interactions – and understand what works in practice.

• 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.
• High standards, low ego: We take our work seriously, but not ourselves. 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.
