Senior IT Administrator

Title: Senior IT Administrator 

Location: McLean, VA – Onsite 5 days/week 

Terms: Full-time 

Salary: $110-$120k DOE

Position Description

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.

• 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

• Administer core business systems including M365, SharePoint, ATS/HRIS platforms (Greenhouse, Paylocity, or equivalent), and other SaaS tools in partnership with HR, Recruiting, and Operations 
• Manage hardware procurement, ISP relationships, and managed service vendors; make cost-conscious, operationally sound decisions on behalf of the company 
• Lead IT components of onboarding and offboarding programs; deliver onboarding training for new hires and ensure a consistent, professional experience 
• Manage and maintain conference room AV equipment, peripherals, and office technology infrastructure 
• Develop and maintain IT documentation: standard operating procedures, runbooks, knowledge base articles, and system configuration records 
• Evaluate new tools and technologies; provide leadership with informed recommendations on IT investments, security improvements, and infrastructure upgrades 
• Partner with leadership on IT strategy: contribute to roadmap discussions, identify gaps in the current environment, and take ownership of improvement initiatives
• Provide leadership for the expansion and adoption of security tools (i.e., Microsoft Defender, Sentinel, and Intune).
