Software Engineer, ChatGPT Infrastructure

Job summary

Responsibilities

We’re hiring Senior and Staff Engineers to design and build infrastructure systems that underlie ChatGPT and multiply the effectiveness of teams building user experiences.

• 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.

What they're looking for

• 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.
