About the role

Senior/Staff engineer role building and operating infrastructure platforms that underpin ChatGPT, focusing on scalable, reliable, and high-performance systems; platform-building role with interfaces, abstractions, and tooling to enable fast, safe iteration across teams.

Responsibilities

  • Build and evolve infrastructure platforms used by many engineers and services.
  • Translate real-world constraints into clean abstractions: simple APIs, enforceable contracts, safe defaults.
  • Drive improvements in reliability and performance through principled design, measurement, and iterative hardening.
  • Partner with engineering and product teams to identify systemic pain points and develop reusable solutions.
  • Own outcomes end-to-end: design → implementation → rollout → operational maturity.

Qualifications

  • Experience building and operating large-scale distributed systems in production (high throughput, concurrency, and failure handling).
  • Strong fundamentals in systems design, including caching, consistency, queueing/backpressure, and resilient dependency management.
  • Ability to reason about performance (latency distributions, tail behavior, bottlenecks) and translate analysis into concrete engineering work.
  • Track record of building platforms or shared infrastructure that improves velocity and correctness for other teams.
  • Excellent communication and collaboration skills—aligning on interfaces, navigating tradeoffs, and driving cross-team execution.
