Key Responsibilities
* Design, develop, and operate high-throughput, low-latency identity services: Single Sign-On (SSO), Multi-Factor Authentication (MFA), session management, and federation. Own features end-to-end from design through production and support.
* Implement and scale modern authentication and authorization protocols and token formats (OAuth 2.0, OpenID Connect, JWTs), including secure token issuance, rotation, and revocation strategies.
* Write clean, concurrent, and highly performant backend services primarily in Go; design idiomatic, testable code and clear API contracts (gRPC/HTTP).
* Use your DevOps experience to deploy, manage, and automate identity infrastructure (CI/CD, monitoring, and incident response).
* Serve as the subject matter expert on authentication and identity: own internal security reviews, threat modeling for identity flows, and guide other teams on secure integrations with our platform.
* Integrate and maintain solutions with custom and standard identity providers (e.g. Keycloak and AWS Cognito), and federation patterns.
* Mentor engineers, conduct design reviews, and contribute to the team's technical roadmap and security posture.

Bring to the Team
* Proven experience building complex, distributed backend systems with strong production experience in Go and gRPC.
* Deep conceptual and practical knowledge of modern authentication and authorization flows, token security, session management, and cryptographic fundamentals (OAuth2, OIDC, RBAC, JWT signing/verification).
* Solid understanding of web security, federated identity, and secure coding practices; familiarity with common web vulnerabilities and mitigations, including the OWASP Top 10.
* Hands-on experience with cloud platforms (AWS preferred), container orchestration (Kubernetes), and Infrastructure as Code (Terraform).
* Experience designing systems for high throughput and low latency without sacrificing security or correctness.
* Strong communication skills: able to explain complex security and architectural tradeoffs to technical and non-technical stakeholders and drive cross-team consensus.
* Experience with SAML, SCIM, PKI, JWKs/JWKS endpoints, key management (KMS/HSM) and token introspection.
* Working knowledge of identity platforms (commercial or open source), rate limiting, abuse mitigation, and adaptive authentication.
