iOS Engineer, ChatGPT Mobile Infrastructure

About the Team

Were building up the core Swift platform from architecture to CI that enables hundreds of engineers (and their agents) to develop new capabilities in ChatGPT Atlas Sora and other rapidly evolving apps. Our focus is helping teams move quickly while improving on performance or reliability.

About the Role

Were hiring Staff engineers with a variety of iOS platform backgrounds including people who may specialize in performance build/CI or AI developer productivity. Whether you focus on UI frameworks or automated testing your work will show up as less friction less complexity fewer regressions and better performance.

If youre rethinking how to scale Swift development in the context of increasingly capable AI tools this is the role for you.

We are hiring in San Francisco New York and Seattle.

In this role you may:

• Build and evolve foundational Swift frameworks used across multiple apps and platforms (caching state management observability navigation component systems).

• Improve app performance (startup responsiveness memory battery) through profiling visibility regression prevention or architecture patterns.

• Strengthen reliability: systemically reduce crashes improve error handling or drive release process improvements.

• Embed with product engineering teams in order to understand pain points or emerging infrastructure needs.

• Develop internal tooling and automation (Bazel CI testing guardrails Codex agent skills and systems) that increase engineering velocity.

• Translate messy real-world constraints into clean abstractions: simple APIs enforceable contracts safe defaults.

You might thrive in this role if you:

• Have strong iOS engineering fundamentals (Swift concurrency networking Xcode ecosystem some UIKit/SwiftUI) and are familiar with the latest features and practices.

• Gravitate towards platform problems: frameworks architecture performance or tools that empower and accelerate others.

• Take ownership: continually identify the biggest risks/opportunities drive projects to completion and update quickly.

• Care about measurement: instrument define metrics run experiments and iterate based on data.

• Have strong communication and collaboration skillsaligning on interfaces navigating tradeoffs and driving cross-team execution.

• Tend to think in systems fight entropy and enjoy an ambiguous challenge.
