The Role

We’re looking for a Senior Diesel Technician with deep experience on large diesel engines to support power generation equipment, rebuilds and complex troubleshooting.

• Interpret engine data, fault codes, wiring diagrams and service manuals
• Support continuous improvement by identifying reliability and maintenance improvements
• Maintain accurate service documentation and reports
• Work closely with engineering and operations teams to resolve complex issues
• Ensure all work complies with safety, quality and company standards

• Minimum 10 years’ experience as a Diesel Technician or Heavy Equipment Technician
• Extensive experience with large‑bore diesel engines
• Strong diagnostic and troubleshooting capability
• Ability to work independently with minimal supervision
• Solid understanding of mechanical, electrical and electronic engine systems
• High attention to detail and strong workmanship standards

• Experience with power generation equipment or industrial applications
• Familiarity with Cummins INSITE or similar diagnostic tools
• Experience supporting rebuilds, upgrades or reliability improvements
• Formal trade qualification (Diesel Technology or equivalent)

• Employer‑paid medical insurance for employee and family
• Employer‑paid group life insurance
• 401(k) with 4% company match
• Employee‑paid dental, vision, short‑term disability and long‑term disability
• Voluntary life, accident, illness and hospital coverage
