About the Role

A fast-growing, Berlin-based enterprise AI platform startup is looking for a Full-Stack Product Engineer to join the team on-site. This is an early-stage opportunity where you'll own features end-to-end, work closely with the Chief Product Officer, and help deliver AI-powered capabilities that drive adoption across large organizations. The company builds a model-agnostic, security-first platform that enables enterprises to roll out AI safely and at scale — from everyday chat assistants to complex automations and custom agents.

Visa sponsorship is available for this role.

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.
• Implement user interfaces including full screens, reusable components, and multi-step user flows.
• Collaborate with the design team and customers to gather insights and iterate on product features.
• Maintain and optimize the codebase for performance and user experience.
• Participate in regular Support Engineer rotations, where engineering team members shift focus to directly support customers and the customer success team.

What We're Looking For

Required:

• 2+ years of experience in software engineering.
• 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 deployment.
• 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 CS fundamentals and ability to learn and adapt quickly in a fast-moving environment.
• Willingness and ability to work on-site in Berlin, Germany (fully remote arrangements are not available for this role).

Nice to Have:

• Experience collaborating with product leadership to shape product direction.
• Background in enterprise SaaS or B2B AI tooling.

Compensation & Benefits

• Salary: €66,000 – €120,000 per year, depending on experience.
• Visa sponsorship available.
• Early-stage equity opportunity at a well-backed AI company.
