Meet the team:

At Dexcom, our Global Security team is redefining what it means to protect a mission‑driven organization. We are more than a protective layer; we are embedded partners in innovation, culture, and care. We work shoulder‑to‑shoulder with teams across the company, utilizing secure‑by‑design principles, enabling innovation, safeguarding trust, and supporting the people who make life‑changing technology possible.

This role isn’t just about security, it’s about leadership, partnership, and impact. You’ll join a team that’s building a modern, proactive security program rooted in strategy, prevention, collaboration, and service. We work cross‑functionally, think globally, and act locally. If you’re energized by complexity, thrive in dynamic environments, and want to be part of a team that’s as mission‑driven as the company it protects, come join us!

As a Site Security Supervisor, you lead the day‑to‑day security operations at your assigned Dexcom facility, ensuring a safe, compliant, and welcoming environment for employees, visitors, and partners. You supervise the contracted guard force, oversee access control and lobby operations, respond to incidents, and work closely with cross‑functional teams to support site operations and mitigate risk.

Where you come in:

• You oversee daily physical security operations, including guard force management, lobby operations, patrols, and access control oversight.
• You conduct daily walkthroughs and safety inspections across lobbies, parking areas, interiors, exteriors, and high‑risk zones, identifying hazards and coordinating corrective actions with Facilities and EHSS.
• You manage onboard/offboard of contracted security staff, validate training compliance, maintain rosters, and ensure proper access provisioning and deactivation.
• You lead daily or shift‑start briefings, perform spot checks on guard performance, and ensure all posts are staffed and supported with required equipment.
• You coordinate on‑site emergency response, act as the incident lead, and liaise with law enforcement, fire, and EMS when needed.
• You support HR/ER investigations by reviewing CCTV, extracting access logs, building timelines, and documenting incidents while maintaining confidentiality.
• You plan and execute security support for on‑site events, ensuring appropriate staffing, access controls, emergency readiness, and a post‑event debrief.
• You monitor incident trends, maintain logs, and compile weekly, monthly, and quarterly reports on incidents, KPIs, staffing, risks, and corrective actions.
• You continuously review physical security procedures for assigned Dexcom locations to ensure industry’s best practices and appropriate mitigation strategies are utilized.

What makes you successful:

• You bring strong leadership skills and excel at guiding contracted guard staff through clear expectations, coaching, accountability, and daily operational support.
• You have a solid understanding of physical security operations, access control systems, CCTV usage, incident documentation, and compliance standards.
• You communicate effectively across functions, engaging professionally with Facilities, HR, EHSS, IT, site leadership, and external responders.
• You are proactive in identifying risks, analyzing incident trends, and implementing preventive or corrective actions.
• You remain calm during emergencies, make quick decisions, and can confidently lead on‑site response and communication.
• You are detail‑oriented, ensuring accuracy in logs, pass‑downs, training records, badge management, and audit documentation.
• You build strong relationships with vendors, ensuring high performance, adherence to standards, and alignment with Dexcom expectations.
• You thrive in a fast‑paced environment and are comfortable adjusting to evolving staffing, operational, and site needs.
• You should have a minimum of three years of experience overseeing security personnel, contracted guard forces, or comparable frontline operational teams in the private sector.
• You should be an active member of relevant security communities (i.e., ASIS, etc.) to stay current on best practices, emerging threats, and industry standards.

What you’ll get:

• A front row seat to life changing CGM technology. Learn about our brave #dexcomwarriors community.
• A full and comprehensive benefits program.
• Growth opportunities on a global scale.
• Access to career development through in‑house learning programs and/or qualified tuition reimbursement.
