Owns versioning, deprecation, rate limiting, and developer onboarding.

Responsibilities

1. Design and maintain canonical LLM APIs (OpenAIcompatible chat/generate, search, ingest, embeddings, responses, interactions) with multimodel backends, consistent across onprem and cloud.
2. Operate Gateway for LLM traffic (SSE/streaming), set TPS and payload SLOs, and coordinate capacity allocations with enterprise gateway owners.

9. Publish OpenAPI specs, SDK examples, and reference integrations ensure parity across environments and models introduced by platform comms.
10. Run performance & soak tests (streaming, batch, embeddings) set promotion gates tied to latency/error SLOs.
11. Coordinate change windows for gateway upgrades and author impact comms/SOPs.
