Backend Engineer building Rust services for an AI safety infrastructure startup. Designing and implementing backend solutions for real-time policy enforcement on large-scale AI systems.

  • Improve system performance, reliability, and observability
  • Work across the stack when needed — solving problems over protecting boundaries
  • Collaborate closely with product, research, and ML teams
  • This is a hands-on role where infrastructure directly shapes how AI behaves in production.

Requirements:

  • Experience shipping and operating services in production
  • Strong communication and ownership mindset

Benefits:

  • Competitive compensation + equity
  • Hybrid setup in Europe + relocation support
  • Comprehensive health coverage
