About the Position

As a Senior Fire Alarm Technician, you're the person others turn to for the tough calls. You'll take on our most complex inspections, verifications, repairs, installs, and retrofits across both addressable and conventional systems, set the standard for quality, and help less experienced technicians grow.

This is a hands-on senior role with real influence. At Mainline, we're building proprietary systems and processes to modernize the industry and make the job better for our technicians and our customers. The people doing the work every day have a real say in how those tools get built.

Key Responsibilities

• Lead complex inspections, tests, verifications, and repairs on fire alarm and life safety systems, including annual, semi-annual, quarterly, and monthly inspections of fire alarms, smoke control, and elevator fire controls.
• Diagnose and resolve difficult issues on both addressable and conventional systems, from ground faults and open circuits to relays and auxiliary devices.
• Install, wire, and program new fire alarm panels and devices.
• Own accurate, on-time documentation of your work and any deficiencies, and resolve those deficiencies as identified.
• Communicate clearly with customers, explaining the work so they understand what was done and why.
• Mentor junior and intermediate technicians, passing on what you've learned on the tougher jobs.
• Take part in after-hours on-call rotations, responding promptly and handling critical issues independently.
• Share feedback from the field that helps us build and improve our proprietary systems and processes.

• Experience with other fire protection services, such as sprinklers and suppression systems, is an asset.
• Valid Class G driver’s licence with a clean driver’s abstract.
• Residency in the GTA or surrounding area is preferred.
• Professionally represent Mainline with a polite, respectful demeanor toward customers and coworkers alike.
