Android Engineer, Chatgpt Mobile Infrastructure

OpenAI OpenAI · AI Frontier · San Francisco, CA · Applied AI

Staff+ Android Engineer focused on building the core Kotlin-based platform infrastructure for ChatGPT, Sora, and other Android apps. The role involves enhancing app performance, reliability, and developer velocity, with a focus on AI developer productivity and internal tooling.

What you'd actually do

  1. Build and evolve core Kotlin frameworks used across multiple apps and platforms (e.g., caching, state management, observability, navigation, component systems).
  2. Enhance app performance (startup, responsiveness, memory, battery life) through profiling, monitoring, regression prevention, or architectural improvements.
  3. Increase reliability by reducing crashes, improving error handling, and driving release process improvements.
  4. Develop internal tooling and automation (CI, testing, guardrails, Codex agent skills, and systems) to accelerate engineering velocity.
  5. Turn real-world constraints into simple abstractions: intuitive APIs, enforceable contracts, safe defaults.
