Job Description

The CIA team is responsible for the infrastructure which supports on-prem and cloud authentication, identity management, and collaboration with productivity suites like Office 365. The ideal candidate is experienced in designing, deploying, operating, and troubleshooting centralized and cloud-based IT infrastructures which form the cornerstone of user authentication and authorization (including AD and AzureAD).

If you dream about optimized OUs and delegations, spent a week getting your end-to-end replication time down to a couple minutes, and converted all your service accounts to GMSAs, then we want to hear from you!

This individual is ideally a self-starter who watches for every area of improvement and proactively drives new solutions to stay ahead the companyโ€™s needs. Working directly with Project Management and other IT teams, this role will guide decisions which shape our services for years to come. This role also works directly with our Security team to review proposed configurations before implementing, and to address any issues with existing infrastructure.

  • Support legacy auth configurations such as LDAP and ADFS


  • 5 yearsโ€™ experience designing, deploying, and managing Active Directory.
  • 5 yearsโ€™ experience using Powershell for automation of system and user management.
  • 5 yearsโ€™ experience engineering new enterprise solutions from requirements gathering through implementation, documentation, and operational handoff.
  • 5 yearsโ€™ experience designing, deploying, and managing MS Group Policy Objects.
  • 2 yearsโ€™ experience designing and managing AzureAD and Azure AD Connect
