Gci Jobs (NOW HIRING)

Step Up. Lead with Purpose. Build the Team Behind the Badge.
GCI Security, Inc. - Greater St. Louis Area

As a Site Supervisor at GCI Security, you'll lead a team of 3-6 unarmed mobile patrol officers at one site. This role will require mostly 2nd shift hours but open flexibility is needed to cover day and overnight shifts in emergency situations.
Site Supervisors are the foundation of our frontline leadership. They set the tone on-site, reinforce GCI's standards, and help identify and develop the next wave of officers ready to lead. You'll work closely with Security Captains and company leadership to improve performance, fill gaps, and elevate the service our clients receive every day.
Starting Pay: $22.00-24.00 per hour (depending on site and experience) with unlimited long-term earnings potential as part of GCI's Fast-Track Leadership Program.
Hours & Schedule: Flexible, full-time schedule with 32 hours spent on patrol and 8 hours completing site check-ins and management/administrative tasks. Evening hours required in order to touch base with evening and overnight shift officers.
For those ready to step up, this role is designed to be a launchpad - not a landing spot. Our goal is to develop field leaders, mobile supervisors, trainers, and even future executives from within. We're building a team of growth-minded professionals, not just shift-fillers. If you're open to learning the business side of security and eventually stepping into customer-facing, leadership, or business development roles, GCI is the place to grow.
