The role

• Automate manual request queues using Okta Workflows, Google APIs, Python, PowerShell, or Bash.

• Partner with the security function on device trust, conditional access, and privileged access.

• Judgment about production and developer access.
• Hands-on with AI tooling in your own work.
• Comfort inheriting something partly built and partly undocumented.
• Calm under competing demands.
