Software Engineer

What You’ll Do: The Cloud Platform API team builds the API platform and the tooling that every other engineering team at CoreWeave uses to ship and consume APIs. This role sits with the group that owns CoreWeave’s Go framework for building API services (server code and tooling), and the client surface it generates: SDKs, the CWIC command-line tool, and the Terraform provider. The team’s charter is "one proto definition should produce every client surface, generated and released the day the API ships." Today that tooling is written by hand, one service at a time, and it lags the API; this role helps make generation the default path. About the role: As a Senior Engineer on API Platform & Client Tooling, you’ll design and build the code-generation pipeline that turns a single proto contract into Go SDKs, CWIC commands, and Terraform resources. You’ll own components end to end, from the proto and API contract through the generated artifacts other teams depend on, and raise the quality bar for the developer experience across that whole surface. Because this team is CoreWeave’s internal API consultancy, you’ll also partner with other teams early in their design process to help them ship good, consistent APIs. Expect a mix of hands‑on Go engineering, API design, and cross‑team collaboration. In this role, you will: Own components of our API services framework (server code and tooling) and its generated artifacts: proto-driven code generation that emits Go SDKs, CWIC commands, and Terraform resources from a single source of truth. Design and ship proto and API contracts, applying schema evolution and backwards‑compatibility discipline, and help author and enforce CoreWeave API Standards in CI. Champion developer experience across the CLI, SDKs, and Terraform provider: ergonomics, release cadence, and the quality bars that make every other CoreWeave team faster. Work across authentication and identity, understanding how auth contracts (access keys, service accounts, JWKS, mTLS, and OIDC) flow from proto into generated clients. Act consultatively: help other teams design and ship good APIs and services. Drive team-level technical initiatives to completion and mentor junior and mid-level engineers. Who You Are: Production experience writing Go. Experience designing and evolving APIs: versioning, backwards compatibility, and deprecation. Experience building or maintaining client tooling: SDKs, CLIs, or infrastructure providers (Terraform, Pulumi, or Crossplane). A track record of owning a project or initiative end to end and operating independently. Clear communication about your technical contributions and how you collaborate. Preferred: Experience with code generation of any kind: codegen pipelines, templating, AST manipulation, or compiler/plugin work. Experience with gRPC and protocol buffers, or another strongly‑typed API/IDL toolchain. Familiarity with the Buf toolchain, ConnectRPC, the Terraform Plugin Framework, or Cobra.
