Nice to have

  • Experience leading or significantly contributing to enterprise-scale Active Directory transformation programs
  • Experience with Entra ID (Azure AD), Okta, or other enterprise identity platforms
  • Experience integrating IAM solutions with cloud and hybrid environments
  • Experience with identity governance, privileged access management, or access lifecycle management platforms
  • Familiarity with open-source technologies and custom platform development

What you get

  • Medical/Dental/Vision/Life, AD&D insurance
