About the role

Hands-on technical leadership role building and optimizing AI frameworks and the serving stack for frontier models (including OpenAI GPT models) across architectures, frameworks, compilers, runtimes, and hardware platforms. Lead technical direction, architecture, and multi-team execution to improve model velocity, platform efficiency, and production reliability.

Responsibilities

  • Own the technical vision, architecture, roadmap, and multi-release execution strategy for critical AI framework, performance, benchmarking, or developer-productivity capabilities.
