IT Systems Engineer/Cloud Administrator (AWS / Hybrid Infrastructure)

We're hiring a Cloud Administrator to support the National Indian Gaming Commission (NIGC), the independent federal agency that regulates gaming on Indian lands under the Indian Gaming Regulatory Act. You'll be the senior technical lead for the agency's server, cloud, identity, storage, and backup environments, covering AWS, VMware, Active Directory, and physical Dell infrastructure.

You'll also be the final escalation point when something breaks. If you're an experienced senior engineer who knows AWS and can also handle on-prem infrastructure, and you want stable, long-term work on a federal contract, this is a strong fit. This position is fully on-site at NIGC Headquarters in Washington, DC.

This is a senior-level position. Candidates must have at least seven (7) years of enterprise systems administration experience, with at least three (3) years at a Tier 3 or senior engineer level. If you do not have hands-on production experience with both AWS and Windows/Linux server administration, please do not apply to this listing.
