## Description

### Job Summary

As a Senior Software Engineer on the API Platform & Client Tooling team at CoreWeave, you will design and build the code-generation pipeline that turns a single proto contract into Go SDKs, CWIC commands, and Terraform resources.

### Responsibilities

- Own components of the API services framework and its generated artifacts, including 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, focusing on ergonomics, release cadence, and quality bars.

- Work across authentication and identity, understanding how auth contracts flow from proto into generated clients.

- Act consultatively to help other teams design and ship good APIs and services.

- Drive team-level technical initiatives to completion and mentor junior and mid-level engineers.

### Requirements

- Production experience writing Go.

- Experience designing and evolving APIs, including versioning, backwards compatibility, and deprecation.

- Experience building or maintaining client tooling, such as SDKs, CLIs, or infrastructure providers.

- A track record of owning a project or initiative end to end and operating independently.

- Clear communication about technical contributions and collaboration.

### Preferred Qualifications

- Experience with code generation, such as 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.

### What We Offer

- Competitive salary: $153,000 to $204,000 per year

- Comprehensive benefits package, including medical, dental, and vision insurance, 100% paid for by CoreWeave

- Company-paid Life Insurance
