About the role

About the Role
A fast-growing, seed-stage enterprise AI platform startup based in Berlin is looking for a Full-Stack Software Engineer to join their small, high-impact engineering team. Founded in 2023 and backed by prominent European and international investors, the company builds a comprehensive, security-first platform that helps organizations adopt and integrate generative AI across their entire operations — including chat, workflows, custom agents, and deep integrations with existing tooling.
This is a full-time, on-site role in Berlin, Germany. Visa sponsorship is available. You'll have substantial ownership over features from conception through production, and direct influence on product and architecture decisions at an early stage.
What You'll Do
Design and implement robust backend systems and APIs powering an enterprise-grade 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, where engineers across the team periodically focus on supporting customers and the customer support team.

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 to production deployment.

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

Solid understanding of API design and integration with third-party services.

Strong CS fundamentals and an ability to contribute to technical architecture and system design discussions.

Excellent collaboration and communication skills across product and engineering teams.

Willingness to work on-site in Berlin, Germany.

Compensation & Benefits
Salary range: $66,000 – $120,000 USD annually (or local equivalent).

Visa sponsorship available for eligible candidates.

High degree of ownership and direct impact at an early-stage, mission-driven company.

Opportunity to shape the product and engineering culture from the ground up.
