About The Position

As an IT Systems Administrator, you will own NODA's corporate IT foundations: endpoint management, identity and access management, onboarding/offboarding, collaboration tooling, and baseline security controls including supporting CMMC. You will ensure every engineer can be productive on day one, every device stays compliant, and our internal systems meet the expectations of government customers and security frameworks. You will work closely with Engineering and DevSecOps to align device posture, identity controls, and audit evidence with our security and compliance requirements. This role is critical to NODA's mission to scale DoD contracts and maintain compliance posture. This role requires a hands-on operator who can move quickly in a startup environment while building repeatable, auditable processes for a growing organization.

Requirements

4+ years of experience in systems administration, IT operations, or corporate IT in a fast-moving environment.
Strong hands-on experience with Jamf (or equivalent MDM) for macOS device management.
Strong hands-on experience administering Microsoft 365 (Entra ID / Azure Active Directory, Exchange, Teams, SharePoint), including onboarding/offboarding and access controls.
Demonstrated ability to build repeatable workflows (documentation-first) for provisioning, access management, and support.
Practical security mindset: least privilege, multi-factor authentication, endpoint encryption, patch discipline, and audit-friendly recordkeeping.
Comfort supporting an office environment (basic networking, Wi-Fi, conference rooms) and remote staff.
U.S. Citizenship with the ability to obtain a security clearance.
