Full-Stack Product Engineer (AI Platform)

About The Role

A fast-growing, seed-stage enterprise AI platform is looking for a talented and proactive Full-Stack Product Engineer to join the team full-time and on-site in Berlin. This is an early-stage opportunity to work at the heart of the product — owning features end-to-end, collaborating closely with the CPO, and shipping AI-powered capabilities that drive adoption across large enterprise organizations.

The company builds a comprehensive, security-first, model-agnostic AI platform that helps enterprises securely adopt and integrate generative AI across their entire operations — spanning chat interfaces, workflow automation, and custom AI agents. The platform is deployed across cloud and on-premise environments and is built with a strong focus on European data compliance and governance.

What You'll Do

• Contribute to the development of product features across the AI platform, from technical design through to user-facing implementation.
• Build end-to-end solutions spanning frontend (Next.js), backend (Node.js), and database layers.
• Collaborate with the design team and customers to gather insights, iterate on features, and refine user flows.
• Implement user interfaces including full screens, reusable components, and complete user flows.
