Senior Software Engineer - API Platform & Client Tooling

CoreWeave's Cloud Platform API team builds the API platform and tooling. As a Senior Engineer, you'll design and build a code-generation pipeline from proto contracts to Go SDKs, CWIC commands, and Terraform resources. You'll own components end-to-end, partner with other teams on API design, and champion developer experience. Requires Go experience, API design, client tooling, and code generation experience.

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). Track record of owning a project end to end. Clear communication. Experience with code generation, gRPC and protocol buffers, Buf toolchain, ConnectRPC, Terraform Plugin Framework, or Cobra.
