About the Role

We're an early-stage, Berlin-based startup building an enterprise-ready, model-agnostic AI platform that helps organizations safely and flexibly roll out AI at scale — from everyday employee chat interactions to complex automations and custom agents. Our platform is used by companies across Europe and emphasizes security, compliance, and flexible deployment (cloud or on-premise).

We're looking for a Full-Stack Software Engineer to join us on-site in Berlin. You'll have substantial ownership from day one, shaping product features end-to-end and contributing directly to architecture decisions in a fast-moving environment. Visa sponsorship is available.

What You'll Do

• Design and implement robust backend systems and APIs to power our AI platform.

• Build end-to-end solutions spanning backend (Node.js), database layers, and frontend integration.

• Develop and optimize database schemas, queries, and data models for performance and scalability.

• Implement API endpoints and integrate with third-party services and AI providers.

• Collaborate on technical architecture decisions and system design alongside the broader engineering team.

• Maintain and optimize the codebase for performance, reliability, and long-term maintainability.

• Participate in rotating Support Engineer duties, where engineers regularly shift focus to support customers and the customer success team — keeping the whole team close to real user needs.

What We're Looking For

Required:

• 3+ years of full-stack web development experience.

• Strong hands-on experience with Node.js, React / Next.js, and TypeScript.

• Proficiency in PostgreSQL and SQL — data modeling, querying, and query optimization.

• Proficiency with Tailwind CSS for frontend styling.

• Experience owning features end-to-end, from conception through production deployment.

• Experience building AI-powered features or integrating AI/ML services into applications.

• Experience designing robust APIs and integrating with third-party services and AI providers.

• Ability and willingness to contribute to technical architecture and system design discussions.

• Strong CS fundamentals.

• Strong collaboration and communication skills across product and cross-functional teams.

• Willingness to work on-site in Berlin, Germany.

Nice to Have:

• Background in enterprise SaaS or B2B productivity tooling.

• Familiarity with compliance, security, or data governance requirements in enterprise environments.

Compensation & Benefits

• Salary: €66,000 – €120,000 per year, depending on experience.

• Visa sponsorship available for eligible candidates.

• Meaningful equity and ownership in a fast-growing early-stage company.

• High-impact role with direct influence on product and engineering direction.
