Senior Software Engineer, Infrastructure
About The Position
About the Team The Statsig team within OpenAI is responsible for the core experimentation, rollout, and analytics infrastructure that powers every layer of OpenAI’s product development stack. Our systems enable teams across OpenAI to safely launch features, run experiments, and understand how product and model changes perform in the real world. Based out of OpenAI’s Bellevue office, we are a tight-knit team that values in-person collaboration, moving quickly with a strong bias toward impact, and building systems that empower other builders across the company. About the Role As a Senior Infrastructure Engineer on the Statsig team, you will build and scale the foundational infrastructure that powers OpenAI’s experimentation and rollout tools. You’ll work on the distributed systems that deliver configuration decisions in real time, ingest massive volumes of experimentation data, and power analytics that help teams understand how product and model changes perform in production. This role is deeply technical and focuses on performance, scalability, and reliability at extreme scale. You will design systems that support billions of feature evaluations, operate with strict latency requirements, and provide the data foundation for experimentation across OpenAI’s product ecosystem.
Requirements
- Have experience building large-scale distributed systems with strict performance and reliability requirements.
- Enjoy solving low-latency systems problems, such as real-time configuration delivery, high-throughput ingestion pipelines, or large-scale analytics systems.
- Have experience building and optimizing large-scale data platforms, event pipelines, etc.
- Care deeply about system reliability, observability, and operational excellence in production environments.
- Take ownership of complex technical problems end-to-end and enjoy building infrastructure that enables other teams to move faster.
Responsibilities
- Design and operate low-latency configuration delivery systems powering progressive rollouts across OpenAI’s product suites.
- Build highly scalable data ingestion and analytics infrastructure to support experimentation, product analytics, and feature performance monitoring.
- Improve the performance, efficiency, and reliability of Statsig’s core infrastructure, ensuring systems remain fast and stable as OpenAI’s products scale globally.
- Optimize query performance and data availability for experimentation and analytics workflows used by teams across OpenAI.
- Lead large technical initiatives and shape the architecture of experimentation and rollout infrastructure used across the company.
