Senior Software Engineer (Identity)

Responsibilities

• Independently scope and deliver medium-to-large projects — take an ambiguous problem, break it into well-sized workstreams, sequence the work, and drive it to completion with minimal hand-holding.
• Partner closely with Product and stakeholders — translate business requirements into technical plans, surface trade-offs early, and keep cross-functional partners informed throughout delivery.
• Set a high bar for quality without sacrificing pace — bring a bias to ship and iterate fast, balanced with the craft and judgment to avoid costly shortcuts.
• Support reliability and incident response — provide on-call and incident support during US working hours to keep the platform healthy and customers supported.

Requirements

• OAuth 2.0, OIDC, SAML, and SCIM provisioning.
• Familiarity with session management, token lifecycle, and secure credential handling at scale.
• Experience building software in security-sensitive or regulated environments (SOC 2, HIPAA, or equivalent).
• Demonstrated ability to independently scope and deliver medium-to-large projects, from ambiguous problem to shipped solution.

Hands-on experience with standards-based identity protocols

Experience integrating with enterprise identity providers (Okta, Entra ID, Ping or similar) and debugging customer SSO configurations in production.
