Role overview
The Developer Experience Architecture team at CarGurus builds the platforms, tooling, and standards that make hundreds of engineers faster, safer, and more productive.

These complex problems will have global impact. You will own well-scoped pieces of work and partner with engineers and product managers across the org, with support and mentorship from senior teammates. And no, you do not need to know about cars to work here.

- Participate in the evaluation of new AI development technologies, libraries, and techniques, sharing findings with the broader team
- Support the rollout of AI tools and practices to engineering teams across CarGurus, including documentation and internal tooling
- Apply our standards, guardrails, and best practices in your work, and help product teams adopt them
- Continuously learn, experiment, and advocate for new technologies and methodologies that can move the business forward
- Investigate, root cause, and improve system reliability and performance
What you'll bring
- Five or more years of hands-on, full-stack software design and development, including at least three years of Python.
- Experience building web applications and working with cloud-native systems on AWS or similar cloud providers
- Production level hands-on exposure to AI frameworks or APIs (e.g. FastAPI, Anthropic, LangChain/LangGraph, LangFuse, Evals)
- Experience using modern AI coding tools (assistants, agents, MCP) on real engineering work, or eagerness to adopt them
- Experience with Java, client and server side JavaScript, and Terraform, is a plus
- Working knowledge of authentication and identity standards (OAuth2/OIDC), or a strong appetite to learn them
- Comfort writing tests, using observability tools, and owning well-scoped tasks end to end
- Curious, collaborative, and eager to learn with strong communication skills
- Bachelor's degree in Computer Science or equivalent
