ARMED SECURITY OFFICER (Overnights, License Required)

**REQUIRED: Current Armed Security License (St. Louis City/County)**

Launch Your Security Career – Paid Training & Promotion Path Available
GCI Security, Inc. – Greater St. Louis Area

POSITION SUMMARY

Security done right. Leadership built from within. At GCI Security, we don’t just post guards — we empower officers to protect with purpose. Armed Security Officers at GCI Security are trusted to uphold the highest standards of protection in environments where safety and accountability matter most. In this role, you’ll provide a strong, visible presence at high-risk or high-value sites, helping to deter crime, support client peace of mind, and respond decisively to potential threats. Our armed officers are trained professionals who understand that presence alone is not enough — clear communication, sound judgment, and unwavering professionalism are essential.

Starting Pay: $22.00 per hour

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.

ABOUT US

At GCI Security, we believe great security is about more than having someone on-site — it’s about trust, presence, and purpose. We’re a locally owned company that was the first to deliver private security services to local taxing districts in St. Louis. Today, we continue to lead the industry by providing worry-free, professional guarding services that protect what matters most.

Our mission is clear: Built to empower. Driven to protect. Trusted to deliver worry-free 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.

At GCI, we don’t just fill shifts — we build careers. Our team lives by five core values: Professionalism. Accountability. Growth. Communication. Integrity. These values shape how we hire, train, and promote from within. If you take pride in your work and want to grow with a company that backs you up, GCI is the place to do it.
