Senior IT Administrator

As Senior IT Administrator at Revolutional, you own the internal technology environment for a growing federal technology company operating out of McLean, VA. This is not a ticket queue role. You are the senior IT practitioner in the building - the person leadership turns to when something needs to get done, a system needs to be evaluated, or a technology decision needs a trusted technical opinion.

You bring 5 or more years of hands-on IT experience across systems administration, infrastructure, endpoint management, and SaaS platform operations. You are equally capable of resolving a complex hardware or software issue and thinking strategically about how Revolutional’s internal IT environment should evolve as the company grows. You work closely with leadership, take initiative without being asked, and hold yourself to a high standard of documentation and operational discipline.

What You Will Own

• Revolutional’s internal IT environment: endpoints, infrastructure, systems, and user support across a 600+ employee organization
• Hardware and software ticket resolution, including escalated and complex issues referred by or involving leadership

• Trusted by leadership: you communicate clearly, follow through consistently, and handle sensitive access and systems with discretion
• Technically broad and operationally reliable - you cover the full IT stack without gaps and keep the environment running with minimal noise
