Work with founders to define and build LiteLLM's second product: talk to customers, design solutions, prototype, and ship production features. Build backend APIs and services with Python and FastAPI, improve developer experiences across API, dashboard, and CLI, and own major product areas end-to-end from concept to production.

Own and triage the support queue for LiteLLM, diagnose and reproduce customer issues, drive root-cause fixes, submit pull requests for bugs, and represent customer needs to engineering.

Founding Developer Relations is a hands-on technical IC who builds runnable demos, sample apps, tutorials, and launch materials; engages and supports the developer community; turns feedback into product improvements; and defines the DevRel strategy and launch processes.

Build and maintain a provider-agnostic LLM interoperability layer: transform OpenAI/Anthropic spec calls to other provider formats, implement session management, support provider features (skills, batching), and improve developer experience via the Python SDK.
