  • Build runbooks and reference architectures for repeatable app onboarding and updates.
• Reliability, Security, and Support
  • Lead L3 incident response and problem management, drive root cause analysis, and implement permanent fixes.
  • Develop monitoring and observability for user experience (logon times, brokering, session stability), infrastructure KPIs, and alerting thresholds.
  • Enforce security best practices: hardening, least-privilege, certificate management, SSL/TLS, and integration with MFA/IdP.
  • Maintain detailed documentation, CMDB accuracy, and change records; contribute to knowledge articles for L1/L2.
  • Participate in an after-hours on-call rotation and support planned maintenance windows.
