Staff / Senior Staff Backend Engineer, B2B Flywheel

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.

Requirements

• 7+ years of professional backend engineering experience, ideally in high-scale, product-driven, or infrastructure-heavy environments
• Strong backend engineering fundamentals, including distributed systems, API services, data modeling, reliability, performance, and production operations
• Experience building or maintaining data pipelines, event systems, logging/telemetry infrastructure, or large-scale data processing systems
• Comfort working near data science, statistics, ML, or research engineering workflows; direct experience is strongly preferred, but not required
• Ability to operate effectively in ambiguous environments where problems are loosely defined and ownership boundaries are broad
• High agency, strong execution velocity, and a willingness to wear multiple hats across backend engineering, data infrastructure, and applied research-adjacent work
• Experience in fast-paced startups, early teams, or similarly high-ownership environments is a plus
• Interest in AI systems, enterprise products, and building the infrastructure that helps improve products and models through real-world usage signals

Benefits

• Generous Paid Time Off
• 401k Matching
• Retirement Plan
• Visa Sponsorship
• Four Day Work Week
• Generous Parental Leave
• Tuition Reimbursement
• Relocation Assistance
