About the Role

Join a product engineering team building AI-powered software for strategic procurement. You will turn complex purchasing data, supplier information, and contracts into practical tools that help customers make better decisions and automate work.

What You'll Do

  • Talk with customers, understand their needs, and help shape product direction.

  • Build and own end-to-end features across data models, AI behavior, backend services, and user interfaces.

  • Create clear interfaces that let users set goals and work with AI agents, including visibility into progress and approval steps.

  • Ship software, learn from real-world usage, and improve product speed and reliability.

  • Experiment with AI engineering tools and improve internal workflows.

What We're Looking For

  • Approximately 1 to 10 years of experience, with scope aligned to mid, senior, or staff level.

  • Professional, hands-on TypeScript experience across frontend and backend development.

  • Practical experience building with large language models and strong engineering fundamentals across frontend, backend, and databases.

  • Experience shipping software to real users, reflecting on post-launch lessons, and owning features end to end.

  • Experience at a startup or small company.

  • Familiarity with React, Next.js, PostgreSQL, Supabase, Vercel, and Python.

Salary range: €90,000 to €140,000 annually. Visa sponsorship is not available.
