Product Engineer (Full-Stack)

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 on-site in Berlin. Founded in 2023, the company builds a comprehensive, security-first platform that helps organizations securely adopt and integrate generative AI — covering AI chat, workflows, custom agents, and integrations across entire business operations. This is an early-stage opportunity where you'll own features end-to-end, work directly with the Chief Product Officer, 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 the 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 journeys. Maintain and optimize the codebase for performance and user experience. Participate in Support Engineer rotations , periodically shifting focus to assist customers and the customer support team alongside the rest of the engineering team. What We're Looking For Must-have: 2+ years of experience in software engineering. Strong proficiency with Next.js, TypeScript, and Node.js (dealbreakers). 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 full-stack development. Nice to have: Experience building AI-powered product features and integrating AI capabilities into enterprise applications. Experience collaborating closely with a Chief Product Officer and cross-functional teams to shape product direction. Strong CS fundamentals with a habit of rapid learning and adaptation. Compensation & Benefits Salary: $66,000 – $120,000 per year (depending on experience). Visa sponsorship is available. Location On-site, Berlin, Germany. This is a full-time, in-person role — remote work is not available for this position.
