Senior Software Engineer, Developer Experience Architecture
About The Position
The Developer Experience Architecture team at CarGurus builds the platforms, tooling, and standards that make hundreds of engineers faster, safer, and more productive. You will work on our highest-leverage initiatives: standardizing AI agentic development (Claude Code, our internal plugin marketplace, and MCP integrations), evolving our authentication and identity platform (Keycloak, OAuth2/OIDC), and improving the paved paths for service and job creation on AWS. These are complex, cross-cutting problems with global impact. You will own your projects and partner with engineers and product managers across the org. And no, you do not need to know about cars to work here.

- Curious, collaborative, and eager to learn
- Bachelor's degree in Computer Science or equivalent
