Product Engineer (Full-Stack)

About the Role

A fast-growing, seed-stage enterprise AI platform company in Berlin is looking for a talented Full-Stack Product Engineer to join their small, high-impact engineering team. Founded in 2023 and backed by top-tier investors, the company builds a comprehensive, security-first AI platform that helps organisations securely adopt and integrate generative AI — from everyday chat and workflows to fully custom AI agents — all within a compliant, European-hosted environment.

This is a full-time, on-site role in Berlin. You'll work closely with the Chief Product Officer and cross-functional teammates to own features end-to-end and ship AI-powered capabilities that drive enterprise adoption at scale.

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 and iterate on product features.

• Implement user interfaces including full screens, reusable components, and complete user flows.

• Maintain and optimise the codebase for performance and user experience.

• Participate in rotating Support Engineer duties, periodically shifting focus to assist customers and the customer support team alongside the rest of the engineering team.

• 2+ years of professional Software Engineering experience.

• Bachelor's degree in Computer Science or an equivalent technical field.

• Proficiency with Next.js , TypeScript , and Node.js .

• Hands-on experience with PostgreSQL , Redis , Prisma , tRPC , and Tailwind CSS .

• Proven track record of delivering features end-to-end — from concept to production — in a full-stack environment.

• Experience building AI-powered product features and integrating AI capabilities into enterprise applications.

• Experience participating in customer support rotations or directly supporting customers during the product lifecycle.

• Strong collaboration skills; comfortable working closely with a CPO and cross-functional teams to shape product direction.

• Solid Computer Science fundamentals with a growth mindset for rapid learning and adaptation.

• Willingness to work on-site in Berlin, Germany — fully remote arrangements are not available for this role.
