The JobWe're looking for a strong generalist Systems Administrator whose core expertise is Active Directory. You'll own the health, security, and day-to-day administration of our AD environment — domain controllers, Group Policy, DNS/DHCP, and the directory structure that everything else depends on — while contributing across the broader IT environment as a versatile, hands-on administrator.
Directory services sit at the foundation of how our users, devices, and applications work together, so you'll partner closely with identity, security, and endpoint teams to keep the environment clean, well-governed, and moving toward modern best practices.

- Administer and maintain domain controllers, including replication health, FSMO roles, backups/recovery, and patching
- Manage core network services tied to the directory: DNS, DHCP, and site/subnet topology
- Harden and secure the directory: tiered administration, least-privilege delegation, privileged account management, and remediation of common AD attack paths
- Support hybrid identity, including directory synchronization to cloud identity platforms and clean attribute/data flows
- Automate routine directory tasks and reporting with PowerShell
- Support day-to-day IT operations across the environment: escalated troubleshooting, server and SaaS administration, and infrastructure projects as needed
- Participate in audits and access reviews with clear evidence from the directory
- Document architecture, processes, and runbooks so the environment is well understood and supportable
• Foster open, respectful, and professional communication directly within the team as well as with co-workers/ teammates and leaders across the organization.
• Performs other duties as assigned.
