Security Officer in Milton Keynes

Position Title: Corporate Security Officer (Relief / Zero Hours)

Reports To: Operations Manager

Location: Flexible with travel across client sites

Contract Type: Zero Hours (Relief / Bank)

About Us

CYS Security is not your typical security company. We are building something different. Our vision is to redefine security as a service that creates safe spaces - environments where people feel secure, supported, and able to perform at their best. We combine professional guarding with intelligence, technology, and a deeply human approach grounded in kindness, integrity, and trust. We are growing quickly, but deliberately. Every person we bring into the business matters.

Role Purpose

This role sits at the frontline of our corporate service delivery. As a Corporate Security Officer within our relief team, you will represent CYS across a portfolio of high-profile corporate environments. You will be deployed flexibly across multiple sites, often at short notice, requiring you to rapidly understand site-specific requirements and deliver a consistent, high-standard service every time. This is not a static guarding role. It requires professionalism, adaptability, and the ability to integrate into different environments without disruption. You are there to maintain safety, protect assets, and contribute to a positive, professional client experience - while embodying our values in every interaction.
