Senior Staff Software Engineer, Identity

We are looking for a hands-on senior technical leader to own the architecture and evolution of OpenAI's Enterprise Identity systems. You will set the long-term technical vision for the entire stack, establish shared identity primitives across products, and be accountable for systems that are foundational to our enterprise business. This role requires operating well beyond a single service or feature area. You will identify the most consequential architectural investments, align teams around durable solutions, and ensure our identity platform meets an exceptionally high bar for scale, availability, latency, and security.

Requirements

Have owned the architecture of a broad, business-critical platform or large-scale distributed-systems domain at the senior-staff level; Have set multi-year technical direction and successfully aligned multiple teams around complex architectural decisions; Understand enterprise identity, enterprise architecture, and the operational needs of large customers in multi-product environments; Have experience with SSO, SCIM, identity providers, tenant models, permissions, groups, or adjacent identity infrastructure; Bring a security-minded, adversarial approach to systems design and instinctively consider how capabilities could fail or be abused; Can move between deep technical judgment, organizational influence, and hands-on leadership where it matters most
