UI Engineer (f/m/d) - AI

Location: Hamburg, Berlin, Gütersloh or Remote (ideally max. 3 hours travel time to Berlin)

You stopped coding.

And that’s exactly why we want you.

AI-First UI Engineer — Building the interfaces of the future

Let’s be honest.

You’ve built apps. Great apps. Maybe some of the best apps out there. You know React and Next.js inside out — the component trees, the state management headaches, the CSS battles at 2am. You’ve shipped production code, debugged impossible bugs, and architected frontends that actually scale.

And then, sometime last year, something clicked.

You realized that writing every line yourself doesn’t make sense anymore. Not because you can’t — but because you’ve found a fundamentally better way. You started building with AI. Cursor, Claude, Copilot, v0 — you tried them all. You fell into every trap along the way. The hallucinated APIs. The spaghetti architecture that AI generates when you don’t guide it. The “works in demo, breaks in production” moments. The missing tests.

But you figured it out.

You learned how to prompt, how to constrain, how to review. You know when to trust AI output and when to throw it away. You’ve developed a workflow that actually produces production-grade, maintainable code — not just impressive demos. You write unit tests. You version properly. You evaluate output quality systematically. You treat AI like what it is: an incredibly powerful tool that needs an incredibly skilled operator.

Now you’re building apps 5x faster than before — and they’re better than what you built manually.

That’s the person we’re looking for.

What we’re building

We’re an AI company building agents as a service . Our agents are powerful — but they need interfaces that make them accessible, intuitive, and delightful. We’re talking natural language interaction UIs, conversational interfaces, agent dashboards, and entirely new interaction patterns that don’t have a playbook yet.

This isn’t about slapping a chat window on top of an API. This is about rethinking how humans interact with AI agents in a business context.

What you’ll do

Own the UI layer — from vision to production. You’re not just writing components. You’re shaping how our product feels.

• Architect and build production-grade frontends for AI agent products using React/Next.js

• Design interaction patterns for natural language and agent-driven UIs — the kind of interfaces nobody has fully figured out yet

• Brief and shape visual design with a strong sense for UX and layout — you don’t need to push pixels, but you need to know what great looks like

• Translate business requirements into product thinking — you understand why we’re building, not just what

• Establish frontend best practices: component architecture, testing strategies, code quality, CI/CD

• Work at the speed of AI while maintaining the quality bar of production software

What makes you - you

The builder who evolved.

You have deep experience shipping real applications — probably years of it. You understand frontend architecture at a level where you can make big decisions confidently: state management, performance, component design, API integration, accessibility.

The AI-native workflow.

You’ve gone through the painful learning curve of AI-assisted development and come out the other side. You know the pitfalls. You have your own system. You can build a complete, production-ready feature in a fraction of the time it used to take — without cutting corners.

The product thinker.

You don’t just build what’s specified. You understand the business context. You push back when something doesn’t make sense. You have opinions about UX and you can articulate them.

The quality bar.

AI-generated code without discipline is a liability. You know this. You write tests. You review thoroughly. You keep architecture clean even when moving fast. You evaluate, iterate, and refine.

Bonus: You’ve been here before.

Ideally, you’ve already worked on AI-first interfaces — conversational UIs, agent interactions, natural language input patterns. You know firsthand what works and what doesn’t when the interface is the AI.

Why this is a rare opportunity

The world is full of developers learning to use AI. It’s full of AI companies building backends. What’s rare is the intersection: someone who deeply understands UI architecture, has genuine product and design sensibility, AND has already mastered AI-first development workflows.

That’s a tiny group of people right now. And we want one of them.

You won’t just be building a product. You’ll be defining what AI-agent interfaces look like — for our company and potentially for the industry. That’s not something you get to do in most jobs.

Interested? Let’s talk.

What matters more than your CV: Show us what you’ve built. A portfolio, a side project, a demo — something that proves you can ship production-quality AI-first applications.

We don’t need a cover letter. Send us a link to something you’ve built with AI, tell us what you learned, and let’s have a conversation.
