Staff / Senior Staff Backend Engineer, B2B Flywheel

ABOUT THE TEAM

B2B Flywheel is a small, high-leverage team working at the intersection of data science, research, and engineering within OpenAI’s B2B organization. The team is focused on building the systems that help OpenAI better understand how businesses and developers use our models, where they encounter friction, and how those signals can improve our products, models, and customer experiences over time.

We operate in highly constrained production environments, including privacy safeguards, low-latency services, and high-traffic API systems. Our work spans real-time backend engineering, data infrastructure, research engineering, and applied data science. The team is small and highly execution-oriented, with broad ownership across the systems that capture, process, and translate critical product and usage signals into better B2B experiences.

About the Role

We’re looking for backend software engineers to help build the data and systems infrastructure behind OpenAI’s B2B flywheel. This role is ideal for someone who enjoys working across backend systems, data pipelines, and applied ML/DS-adjacent problems — especially in ambiguous, fast-moving environments where the path is not always predefined.

You’ll help design and build real-time engineering systems that operate across high-scale API and B2B surfaces, while partnering closely with data science, research, product, and engineering teams. Strong candidates will bring deep backend engineering ability, comfort with data-heavy systems, and the versatility to work across multiple technical domains.

In this role, you will:

- Design, build, and operate backend systems that capture and process critical product, usage, and customer signals across B2B and API surfaces

- Build reliable data pipelines and infrastructure that help translate raw signals into actionable insights, model evaluations, training datasets, and product improvements

- Work on high-traffic, low-latency services in constrained environments, i...
