The Identity Lifecycle: You will own the core services responsible for authenticating every entity, human and machine, within the ecosystem. This includes managing the trade-offs between stateless scalability and real-time session revocation.
Authorization Strategy: You will be defining how fine-grained permissions are modeled, inherited, and enforced across a massive, multi-tenant hierarchy of organizations and locations.
The "Paved Road" for Developers: You will own the internal SDKs, gRPC contracts, and middleware that allow over 150+ downstream engineers to integrate security features into their products without needing to be cryptography experts.

What you'll need to accomplish the job:

Experience: 5+ years of backend engineering with significant time spent building distributed systems in Go.
Domain Expertise: Deep understanding of AuthN/AuthZ primitives: OAuth 2.0, OIDC, SAML, and JWT mechanics.
System Design: Proven ability to manage complex data migrations, distributed architecture and build gRPC-based microservices.

What will make us love you:

The "Founding" Spirit: You have previously been an early member of a distributed team and understand how to build culture across time zones.
Security Mindset: You treat "Zero-Trust" as a default, not a buzzword, and have experience with Zanzibar-style authorization or SpiceDB.
Reliability Obsession: You don't just ship code; you ship alerts, dashboards, and runbooks.
