Software Engineer, Product - Core Experimentation

Details

The Statsig team within OpenAI builds experimentation, feature rollout, dynamic configuration, and analytics systems that help teams ship products with speed, safety, and evidence. The platform supports ChatGPT, Codex, model measurement, consumer experiences including ads, business subscriptions, developer products, and shared infrastructure.

The team is bringing Statsig's product expertise and platform infrastructure into OpenAI as the experimentation and rollout platform for every product the company ships. Recent SDK and server-side infrastructure work has improved latency, reliability, memory usage, and compute efficiency for important services.

Responsibilities

• Build product experiences and platform capabilities for experimentation, feature flags, dynamic configuration, rollout safety, and analytics.
• Partner with product teams to understand launch workflows, measurement needs, and decision points, then turn those insights into durable platform features.
• Improve SDK and server-side systems so experimentation and configuration are fast, reliable, and safe for high-scale OpenAI services.
• 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 supporting rapid adoption, high availability, and increasingly sophisticated product and model evaluation needs.
• Collaborate across frontend, backend, SDK, data, and infrastructure surfaces.
• Work with the team in person from the Bellevue office.

Requirements

• Strong full-stack engineering judgment.
• Interest in building product surfaces on top of significant platform and infrastructure constraints.
• Strong focus on developer experience and making experimentation concepts intuitive for product teams.
• Ability to work across customer conversations, product design, backend architecture, SDK behavior, and data-informed decision-making.
• Ability to balance performance, reliability, and product quality.
• Interest in influencing how OpenAI ships products across ChatGPT, Codex, model measurement, consumer monetization, business products, and future product surfaces.
• Value for in-person collaboration, ownership, clear communication, and high-trust teamwork.
