  • Improve performance, reliability and observability across backend components.
  • Collaborate with compiler engineers to integrate new compiler capabilities into production systems.
  • Work with researchers and product teams to deliver new platform capabilities.
  • Learn and contribute to compiler infrastructure as your expertise grows.
Ideally, you'll have:
  • Bachelor's degree in Computer Science, Engineering or related discipline.
  • Strong programming skills in Python.
  • Experience with modern C++.
  • Experience building backend systems or distributed services.
  • Experience designing APIs using REST, gRPC or GraphQL.
