AI Fullstack Engineer – Remote (or Berlin HQ)

What if you could ship GenAI-powered tools that are used within days - not months - and see their impact in real-world workflows across Europe and the US?

We’re partnering with a nimble, Berlin-based AI product company delivering production-grade GenAI systems to high-impact clients in healthcare, financial services, logistics, and more. Their mission? Redefining business processes through tailored AI agents that solve real problems, not just demo well.

With 30+ successful deployments under their belt, they’re scaling fast, and looking for an AI Fullstack Engineer who can own the delivery of full-stack GenAI workflows with a strong UI and user-centric focus.

This is a hybrid role at the intersection of product, engineering, and deployment. You’ll prototype fast, collaborate directly with stakeholders, and turn ideas into robust tools - sometimes embedded in the problem space, always solving something messy.

What you’ll do

- Build full-stack GenAI applications, from React-based UIs to backend logic and API integration.

- Rapidly prototype, test, and deploy working tools to create user value in ambiguous environments.

- Work closely with end users, stakeholders, and ops teams to refine, adapt, and improve functionality.

- Own the delivery of bespoke AI-powered workflows, including orchestration, RAG, and automation.

- Contribute to a growing internal toolkit of reusable UI components, design patterns, and GenAI infra.

What we’re looking for

- 5+ years of full-stack with strong front-end engineering experience, ideally with strong Next.js, React, and TypeScript.

- Demonstrated ability to ship production systems fast, not just polished prototypes.

- Experience working in ambiguous, dynamic environments, startup, scale-up, or consulting.

- Exposure to GenAI systems (OpenAI, LangChain, RAG, vector DBs) or a fast learner hungry to dive in.

You might be a fit if you...

- Like working close to the user, where feedback is immediate and the stakes are high.

- Think in terms of outcomes, not just tools.

- Can context switch quickly and work across UI, logic, and system integration.

- Prefer iterative shipping over perfection.

What’s on offer

- Remuneration: Up to €100 000 p/y (Freelance or Internal).

- Remote-first work setup (with optional Berlin HQ access).

- A product-first culture where everyone builds, no dead weight, no fluff.

- Direct impact and fast deployment cycles, your work will ship, often in days.

- Exposure to global clients and cutting-edge GenAI problems across industries.

- A sharp, supportive team solving meaningful problems with custom AI.
