  • Generator controls and electrical diagnostics
  • ATS and emergency power systems
  • Independent field troubleshooting

We are looking for a technician who can confidently diagnose and repair complex generator and engine issues in the field, lead service calls independently, and represent the company professionally with customers.

This is not a general maintenance position — candidates must have hands-on experience with diesel engines, power generation equipment, and electrical troubleshooting.

    • Automatic Transfer Switches (ATS)
    • AC/DC electrical systems up to 600V
    • 24V DC starting and charging systems
    • Governors, AVR systems, relays, and control circuits
  • Read and interpret electrical schematics and wiring diagrams
  • Perform preventative maintenance and emergency service repairs on generator systems
  • Conduct load bank testing and system commissioning when required
  • Lead field service jobs independently and make sound technical decisions under pressure
  • Support and mentor junior technicians when needed
  • Complete accurate service documentation and reports
  • Communicate professionally with customers and maintain strong client relationships
  • Participate in an on-call rotation after onboarding

 

Required Qualifications

  • 5+ years of experience working on:
    • Industrial diesel generators
    • Power generation equipment
    • Heavy diesel engines
    • Generator field service
  • Proven experience independently performing diesel engine overhauls
  • Strong electrical troubleshooting experience with:
    • 24V DC systems
    • AC electrical systems up to 600V
    • Generator controls and ATS systems
  • Experience reading electrical schematics and troubleshooting control circuits
  • Ability to work independently in the field with minimal supervision
  • Strong troubleshooting and diagnostic skills
  • Valid driver’s license with clean driving record
  • Must own personal tools
  • Willingness to travel throughout Southern Ontario, including overnight stays when required

 

Schedule & Travel

  • Field-based role servicing customers across Southern Ontario
  • Technicians dispatch directly from home
  • Overnight travel required (typically 2–3 nights per month)
  • Limited weekend work
  • On-call rotation after training period

Compensation & Benefits

  • $40–$45/hour based on experience
  • Paid overtime
  • Paid travel time
  • Company vehicle
  • Company phone
  • $500 annual tool allowance
  • Comprehensive benefits package
