As a Security Engineer, your primary objective is to ensure the continuous operation of fire and security systems. You will spend a significant portion of your time traveling between client sites, performing planned preventative maintenance, and responding to reactive service calls.

Your day-to-day work involves rigorous testing of sensors, control panels, and communication links to ensure they meet performance specifications. You will also be responsible for maintaining accurate service logs and providing clear updates to both your management team and the client. Collaboration is key; while much of your work is independent, you will regularly coordinate with office-based support teams to source parts or seek technical guidance for complex system integrations.
