  • MFA and advanced authentication factors

  • SCIM and identity lifecycle management

• Experience integrating and customizing third-party identity platforms (e.g., Auth0, Okta, WorkOS) at scale.

• Strong architecture and systems design skills for distributed, multi-tenant SaaS environments.

• Proven track record of delivering IAM features in security-sensitive, high-uptime environments.

• Solid programming experience in Python, Go, or similar languages, plus comfort with IaC (Terraform, Atlantis, Crossplane).
