Senior Staff Backend Software Engineer, B2B Applications
B2B Applications - San Francisco
About the Team
OpenAI’s mission is to make AGI beneficial for all of humanity and our mission is successful only if AGI drives real benefits across all industries in the world. Our goal in B2B applications is to enable this mission by helping businesses, enterprises & governments redefine how they operate to empower people and accelerate economic growth. We build and operate the products that bring our cutting‑edge research to millions of companies and developers worldwide. We power the OpenAI API and the Enterprise products that empower people around the world to do their jobs better and more efficiently. Our teams span product engineering, backend infrastructure, and safety, working together to ensure that OpenAI’s technology is delivered with reliability, security, and a world‑class user experience.
About the Role
We’re looking for backend engineers to design and scale the systems that drive our developer and enterprise‑facing products. In this role, you’ll architect and maintain the services and infrastructure that power OpenAI applications—from large‑scale distributed systems and databases to APIs and data pipelines. You’ll collaborate closely with product, research, and infrastructure teams to bring new AI capabilities to production while ensuring performance, safety, and compliance at global scale.
In this role, you will:
Own the end‑to‑end development lifecycle for new platform capabilities and integrations with other systems
Collaborate closely with product, design and external customers to understand problems and implement effective solutions
Work with the research team to improve our next generation of models
Your background might look something like:
9+ years of professional engineering experience (excluding internships) in relevant roles at tech and product‑driven companies
Former founder, or early engineer at a startup who has built a product from scratch is a plus
Proficiency in one or more backend languages (e.g., Python, Go, Rust, Typescript or similar) and distributed systems concepts.
Enjoy building infrastructure that supports billions of requests and petabytes of data.
Care deeply about reliability, safety, and performance in production environments.
Interest in AI/ML (direct experience not required)
Proven ability to thrive in fast‑growing, product‑driven companies by effectively navigating loosely defined tasks and managing competing priorities or deadlines.
Title note
At OpenAI, research and engineering hires share the internal title Member of Technical Staff. We use Senior Staff externally to signal the depth of experience, ownership, and technical leadership expected for this role.
