Security done right. Leadership built from within. At GCI Security, we don’t just post guards — we empower protectors. As an unarmed security officer, you’ll play a critical role in delivering worry-free protection to the people and places we serve. Whether stationed at a residential neighborhood, retail store, or office building, your presence will provide peace of mind through professionalism, visibility, and vigilance. Our officers are the frontline ambassadors of our mission: to protect with purpose and represent our values every shift.

Starting Pay: $18.00 - 20.00 per hour (depending on experience)

This is more than a job — it’s a launchpad. We’re actively looking for individuals with the ambition to rise through the ranks into leadership, operations, and executive-level roles within our rapidly growing company. 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.

ABOUT US

At GCI Security, we believe great security is about more than having someone on-site — it’s about trust, presence, and purpose.

Our mission is clear: Built to empower. Driven to protect. Trusted to deliver worry-free security guarding at the highest standard.

We serve private neighborhoods, corporate offices, retail properties, industrial sites, and more — delivering proactive protection through visible presence and responsive service.
