Drive operational excellence: establish and refine SLAs/SLOs, observability, automated testing, incident response, and postmortems to reduce MTTR and improve service health. Partner with Product, Security, Architecture, and Legal to translate requirements into secure, testable designs and threat models; influence cross‑org auth strategy and policy. Coach and grow engineering talent (individual contributors and tech leads); hire and retain engineers aligned to team needs; foster an inclusive, collaborative culture. Make technical tradeoffs and participate in architecture decisions for distributed access management systems, capacity planning, and scaling throughput. Coordinate resource planning and delivery across time zones to meet quarterly and long‑term goals. Required 8+ years software engineering experience and 2+ years managing engineering teams. Experience building and operating high‑scale services and APIs in production environments. Familiarity with identity and access management industry standards: SSO (SAML, OIDC), OAuth2, MFA, session/token management, account lifecycle, abuse/fraud mitigation patterns. Excellent communication skills, both written and verbal—representing the organization’s work to senior leadership and communicating trade‑offs clearly. Preferred Prior experience operating and scaling identity and access management systems in a production environment. Data‑driven decision maker adept at using data to prioritize work and influence stakeholders. Familiarity with backend languages/platforms commonly used for identity services (e.g., Go, Java/Kotlin, Node) and cloud providers (AWS/GCP). Experience with privacy and compliance frameworks relevant to authentication (SOC2, ISO, GDPR). Track record of completing complex zero‑downtime systems migrations in a production environment. AI Literacy Requirement Candidates must be comfortable using AI‑powered tools to increase engineering productivity (e.g., code assistance, test generation, incident analysis), understand risks and limitations of AI in security contexts, and be able to lead responsible, risk‑aware adoption of agentic AI for authentication use cases.
