• Build APIs and automation to simplify identity platform operations.
• Partner with engineering teams to deliver reusable, secure authentication services.
• Improve operational maturity through monitoring, alerting, logging, documentation, and automation.
• Support migration away from bespoke authentication implementations towards enterprise IAM standards.

Requirements

• Experience engineering and operating enterprise IAM platforms.
• Experience with enterprise identity providers such as PingFederate, PingAM, Microsoft Entra ID, or Okta.
