  • Help teams across ChatGPT, Codex, model measurement, ads, business: subscriptions, developer products, and infrastructure use Statsig effectively.

  • Design workflows that make it easier to create experiments, interpret: results, monitor rollouts, and act quickly when a launch needs adjustment.

  • Contribute to the technical direction of a platform that must support rapid: adoption, high availability, and increasingly sophisticated product and model evaluation needs.

What they're looking for

  • Work from the Bellevue office with a team that values ownership, clear: communication, and high-trust collaboration.
  • Have strong full-stack engineering judgment and enjoy building product: surfaces that sit on top of serious platform and infrastructure constraints.
  • Care deeply about developer experience and can make powerful experimentation: concepts feel intuitive to busy product teams.
  • Are excited by the post-acquisition chapter of a high-performing team: preserving what made Statsig strong while integrating deeply into OpenAI’s product development system.
