Software Engineer, Enterprise Identity

About the Team
OpenAI’s Enterprise Identity team builds the trust and control layer that enables organizations to adopt AI safely at scale. We design and operate the core authentication, authorization, and enterprise access systems that power OpenAI’s products for businesses of all sizes — from startups to the world’s largest organizations. Our work sits at the intersection of security, platform infrastructure, and enterprise IT, ensuring that administrators can manage users, permissions, and integrations with confidence while employees experience seamless access to powerful AI tools. By building secure, scalable identity foundations, we make it possible for enterprises to deploy AI responsibly, integrate it into their workflows, and unlock its value across the organization.

About the Role
As a Software Engineer on OpenAI’s Enterprise Identity team, you will lead the development of the identity platform that enables organizations to securely adopt OpenAI at scale. You’ll design, build, and evolve core enterprise identity capabilities — including SSO, SCIM, RBAC, and identity federation — that power access across all OpenAI products. This role sits at the heart of enterprise trust, directly supporting our most critical customers and shaping how businesses deploy AI safely within their organizations. You’ll work closely with product, security, and platform teams to deliver systems that meet the highest standards of reliability, security, and scalability, while balancing enterprise requirements with seamless user experience. Your work will have broad, long-term impact, unlocking large-scale enterprise adoption of OpenAI’s models and products.

In this role, you will:

• Architect and build the next generation of enterprise authentication and authorization infrastructure, powering secure integrations across SAML, OIDC, and OAuth 2.0.

• Design and deliver core enterprise identity capabilities — including SSO, SCIM provisioning, RBAC, and delegated access — that enable organizations to manage access with confidence at scale.

• Evolve the identity data model and system architecture to support complex, real-world enterprise structures spanning teams, domains, subsidiaries, and global organizations.

• Partner closely with go-to-market, security, and product teams to shape identity features that meet the needs of customers ranging from fast-growing startups to multinational enterprises.

• Build high-leverage tools, APIs, and primitives that make it easy for engineering teams across OpenAI to integrate enterprise identity seamlessly into their products.

You might thrive in this role if you:

• Have 5+ years of experience building and operating production backend systems, with exposure to authentication, identity, or access control in real-world environments.

• Are comfortable working with identity protocols such as OAuth 2.0, SAML, SCIM, SSO and OIDC, and are eager to deepen your understanding of their security implications and edge cases.

• Are a solid backend engineer (Python preferred) who enjoys designing reliable systems, writing clean APIs, and thinking carefully about security, privacy and correctness.

• Has operated and worked in high-traffic and large scale systems.

• Like owning problems end-to-end, from design through production, and learning new domains as needed to deliver high-quality results.

• Are motivated by the opportunity to help shape how enterprises securely access and govern the use of frontier AI technologies.
