You will lead the transition from legacy authorization to a modern, globally distributed Identity and Access Management (IAM) platform powered by SpiceDB and Go. This is a high-leverage role requiring a blend of secure backend engineering and the leadership maturity to grow a new regional hub for a Tier-1 infrastructure unit. You’ll thrive here if you care deeply about customers, lead with curiosity, and live by our core values: Think creatively. Stay hungry. Do the right thing. Care more. The customer is everything. If you're excited about transforming healthcare with purpose-driven work and smart teammates by your side, we'd love to meet you.

• This position will be remote
• Reports to: Manager of Engineering - Users Infrastructure WHAT YOU’LL OWN
• 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.
• Enterprise Integration Standards: You will manage the infrastructure that bridges our platform with the world, including federated identity (SSO), automated provisioning (SCIM), and secure machine-to-machine (M2M) communication protocols.
• Operational Excellence: Improve system observability (MTTD/MTTR) by integrating monitoring and load-testing protocols into our Tier-1 services.
• Systemic Integrity & Compliance: You are the guardian of the "Source of Truth." You will own the immutability and reliability of our audit logging pipelines and the consistency of identity data.
• India Team Trajectory: As a founding member of the regional hub, you will own the technical bar and operational culture for the India-based arm of the team, ensuring seamless asynchronous collaboration with the US-based team members.. 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 (in any or all of these areas): 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.
• Communication: Exceptional written clarity; the ability to write Technical Design Documents (TPDs) that bridge the gap between India and US-based stakeholders. 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 (and you have a "stop-and-fix" mentality).
