Senior Field Technician

About the role

Minuteman Security Solutions, LLC is an electronic security systems integrator supporting U.S. government and defense organizations. We design, install, and sustain the access control, intrusion detection, and video systems that protect people, facilities, and critical assets. Our technicians are trusted to solve problems thoroughly, document work accurately, and represent the company professionally on active client sites.

As Senior Field Service Technician, you will be the primary on-site technical lead for sustaining enterprise electronic security systems, with an emphasis on Lenel OnGuard, at federal and DoD facilities across the Washington, D.C. metropolitan area. Your primary responsibility is restoring and maintaining system availability through advanced diagnostics, preventive maintenance, configuration validation, and complete service documentation. You will own complex issues from diagnosis through resolution, coordinate work with project managers, engineers, client representatives, and government stakeholders, and guide junior technicians. To support our customers’ needs, occasional extended travel outside of the DMV area may be required, to include both CONUS and OCONUS locations. When needed, you will be notified well in advance of the required travel date and provided sufficient time to plan and prepare accordingly.
