Senior Product Engineer (f/m/d)
Berlin, Germany
Full-Time | Onsite | Permanent

About the Company
You've been one of three or four engineers on a small team, building across the whole stack and shipping to production yourself. You like it that way.
What you want now is a place where your ideas actually change what gets built, and you can grow

Our client is a high-growth technology business using software, automation, and AI to redefine how one of Europe's largest and most important industries operates.
Having achieved significant scale with a lean team, they are now looking for a Senior Product Engineer to help build the next generation of their platform.

This is a fully onsite role in Berlin, working closely with founders, product leaders, and designers in a fast-paced, highly collaborative environment.

The Role
You'll own features from idea to production, building across the stack in TypeScript with modern technologies including React and Node.js.
Working closely with Product, Design, and end users, you'll help translate complex operational workflows into intuitive, AI-enabled software.
Beyond shipping features, you'll contribute to architectural decisions, improve system performance and reliability, and help shape engineering practices as the team continues to grow.

What We're Looking For
  • Strong commercial experience building and operating production web applications.
  • Strong TypeScript skills with experience in React and Node.js (or similar modern full-stack environments).
  • Comfortable owning features end-to-end, from discovery through deployment.
  • Solid understanding of APIs, frontend architecture, state management, and backend systems.
  • A proactive mindset with strong ownership and the ability to make decisions in ambiguous environments.
AI-Native (Essential)
Being AI-native is a core requirement for this role. The team actively embraces AI-assisted development and agentic tooling, and you'll be expected to use AI as a natural part of how you build, experiment, and solve problems.
Strong engineering fundamentals remain essential — this role is for someone who can combine modern AI workflows with sound technical judgement.

Why Join?
  • Work directly with founders and senior leadership.
  • High ownership and autonomy from day one.
  • Influence product and technical direction.
  • Help modernise a major industry through technology and AI.
  • Join an ambitious team where your impact will be immediate and visible.
If you're looking for an environment where great ideas are heard, ownership is real, and AI is central to how products are built, we'd love to hear from you.
