About The Role
A fast-growing, seed-stage enterprise AI platform company based in Berlin is looking for a
Full-Stack Software Engineer
to join their small, high-impact engineering team. Founded in 2023, the company builds an all-in-one platform that enables organisations to securely adopt and integrate generative AI — including AI chat, workflows, and custom agents — across their entire operations.

This is a full-time, on-site role in Berlin with substantial ownership from day one. You'll shape product features, drive architecture decisions, and ship quickly in a fast-paced early-stage environment.
Visa sponsorship is available.
What You'll Do

• Design and implement robust backend systems and APIs powering a scalable 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/ML providers.
• Collaborate with the team on technical architecture decisions and system design.
• Maintain and optimize the codebase for performance, reliability, and maintainability.
• Participate in rotating Support Engineer shifts, in which engineers periodically focus on supporting customers and the customer success team.

What We're Looking For

Required

• 3+ years of full-stack web development experience.
• Strong proficiency with Node.js, React / Next.js, and TypeScript.
• Solid command of PostgreSQL and SQL — data modeling, querying, and optimization.
• Experience with Tailwind CSS for frontend styling and implementation.
• Proven track record 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.
• Strong CS fundamentals and communication skills across product and cross-functional teams.
• Willingness to participate in periodic support engineer rotations.
• Ability to work on-site in Berlin, Germany (visa sponsorship available).

Compensation & Benefits

• Salary: €66,000 – €120,000 per year, depending on experience.
• Visa sponsorship available for eligible candidates.
• High degree of ownership and direct impact at an early-stage company.
• Opportunity to contribute to foundational architecture decisions as the team scales.

role based in
