  • At least five years of direct experience developing customer-facing APIs within a team
  • Thoughtful and efficient communication skills (both verbal and written)
  • Experience developing RESTful APIs using a variety of tools
  • Experience turning abstract business requirements into concrete technical plans
  • Experience working across many stages of the software development lifecycle
  • Sound reasoning about the behavior and performance of loosely-coupled systems
  • Proficiency with algorithms (including time and space complexity analysis), data structures, and software architecture
  • At least one domain of demonstrable technical depth
Technologies & Tools We Use :
  • Development: Python, Flask, FastAPI, Django REST Framework, PostgreSQL, Celery, RabbitMQ, Redis, Kafka, Jsonnet, Agentic Coding Tools (Claude Code, Codex, Cline)

  • 401(k) plan with 6% employer matching
  • Generous company matching on donations to non-profit charities
  • Up to $20,000 tuition assistance toward degree programs, plus up to $4,000/year for ongoing professional education such as industry conferences
  • Plentiful snacks, drinks, and regularly catered lunches
  • Dog-friendly office (CAM office)
