About the role

Infrastructure engineer building and scaling OpenAI's experimentation and rollout platform (Statsig), focusing on low-latency configuration delivery, high-throughput data ingestion, analytics infrastructure, and reliable, scalable systems to support OpenAI product releases.

Responsibilities

  • Design and operate low-latency configuration delivery systems powering feature flags, dynamic configs, and progressive rollouts across OpenAI product suites.
  • Scale SDK, server-side evaluation, and control-plane systems so high-volume services can depend on Statsig without adding user-visible latency or operational fragility.
  • Build high-throughput data ingestion and analytics infrastructure for experimentation, product analytics, feature performance monitoring, and model or product measurement workflows.
  • Improve performance, efficiency, reliability, and observability of core Statsig infrastructure as OpenAI products scale globally.
  • Optimize query performance, data freshness, and data availability for teams making launch decisions from experimentation and analytics workflows.
  • Strengthen operational excellence through better SLOs, alerting, debugging tools, incident response, capacity planning, and failure-mode design.
  • Partner with teams across ChatGPT, Codex, model measurement, consumer ads, business subscriptions, developer products, and infrastructure to turn recurring launch and measurement needs into durable platform capabilities.
  • Lead large technical initiatives and shape the architecture of experimentation and rollout infrastructure used across the company.

Qualifications

  • Have experience building large-scale distributed systems with strict performance, availability, and correctness requirements.
  • Enjoy low-latency systems work, including real-time configuration delivery, SDK/runtime performance, caching, concurrency, and high-throughput service design.
  • Have built or operated large-scale data platforms, event pipelines, analytics systems, or query infrastructure where freshness and correctness matter.
  • Care deeply about reliability, observability, incident response, capacity planning, and the practical craft of keeping critical production systems boring in the best way.
  • Are excited by the post-acquisition chapter of a high-performing infrastructure team: preserving Statsig's strengths while integrating deeply into OpenAI's product and platform stack.
  • Want to work on infrastructure that directly affects how ChatGPT, Codex, model measurement, ads, business subscriptions, developer products, and future OpenAI surfaces ship.
  • Take ownership of complex technical problems end to end and enjoy building infrastructure that lets other teams move faster with more confidence.
