Hadrian is rebuilding America’s industrial strength, rapidly scaling our country’s manufacturing output through advanced software, automation, and human skill. Backed by a16z, Founders Fund and Lux.
About the role
As our Senior Identity Engineer, you will own workforce and workload identity end-to-end — SSO, MFA, the joiner-mover-leaver lifecycle, privileged access, secrets, and service/machine identity — across corporate, cloud, and factory systems that handle export-controlled technical data. You will build an automation-first, least-privilege identity program that shrinks our largest attack surface while keeping engineers fast. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- You can build. Strong software engineering fundamentals and a track record of shipping identity systems at scale — not just configuring a vendor tool or leaning on AI-assisted coding
- Real command of core identity concepts — OAuth 2.0 flows, OIDC, SAML, RBAC, and relationship-based access control (ReBAC) — and the ability to design systems that exploit these protocols well
- Hands-on depth with one or more IdPs (Okta / Entra / Google Workspace / Auth0 / Zitadel), since day-to-day is implementing, designing, and integrating these platforms
- Cloud identity depth — Azure service principals, AWS IAM — and a clear grasp of how those identities map to real infrastructure
- The autonomy and urgency to own the identity domain end-to-end on a small, high-leverage team with minimal direction
