  • Past experience in developer tools or API platforms.

Responsibilities

  • Leading the design and evolution of backend systems that power request sending, local runtimes, and telemetry for the API client.

  • Migrating services to Kubernetes-based infrastructure with a focus on performance, security, and cost efficiency.
  • Defining new baselines for clean, fault-tolerant, and maintainable services that scale across millions of users.

  • Identifying bottlenecks and building tools to improve the API client experience

  • Full medical coverage, flexible PTO, wellness reimbursement, and a monthly lunch stipend.
  • 3-days a week in-office work model for employees based out of San Francisco Bay Area, Boston, Bangalore, Hyderabad, and New York
