Senior Diesel Technician
At JC Davis Ventures, LLC dba JC Davis Power, we keep work moving with smart, reliable solutions that allow our people and our partners to stay safe, focused, and ahead.

We started JC Davis Power to fix all of that. We’re a full-service jobsite operations partner, delivering and maintaining temporary power, climate control, and associated services.. All with one reliable crew. No handoffs. No confusion.
We show up, set up, and keep your site running, so you can stay focused on the work that matters.
Simple - Reliable - Done Right.
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.

This role plays a critical part in supporting reliability, rebuild quality, and continuous improvement across our power generation fleet.
Strong preference for experience on Cummins QSX15, QST30, and QSM11 engines.

Perform engine rebuilds, top-end overhauls, and major component replacements
Troubleshoot mechanical, electrical, and electronic engine systems
Conduct inspections, commissioning, and functional testing
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
What We’re Looking For
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
What Will Set You Apart
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)
Compensation & Benefits
Employer-paid medical insurance for employee and family
