About The Position

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. Powering a jobsite shouldn’t be a hassle. But too often, crews are left waiting, equipment breaks down, vendors go dark, and deadlines slip. 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.
