\n

You partner with local leadership to support recruiting, hiring, onboarding, training, and employee development.

You also work closely with client leadership across multiple business groups to support site operations.

Operationally, you ensure compliance with security policies, procedures, and standard operating guidelines. You monitor site performance and key metrics, identify risks or security gaps, and drive corrective actions and continuous improvement. You maintain required documentation, logs, and reports, oversee on‑site security systems such as access control, CCTV, and incident management tools, and support audits, inspections, and other compliance activities. . . The role requires clear, professional communication with clients and internal partners, including leading meetings and presentations.
