- 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.
