Diesel Technician Jobs in California: Frequently Asked Questions

How do you become a diesel technician in California?

California does not require a state-issued license to work as a diesel technician, but ASE certification is the industry standard most employers require before or shortly after hiring. The typical path starts with a diesel technology program at a California community college such as those offered through the California Community Colleges system, followed by an apprenticeship or entry-level shop position. Earning ASE Medium/Heavy Truck certifications, particularly in engines and brakes, strengthens your candidacy significantly.

How much do diesel technicians make in California?

Diesel technicians in California earn a median of about $73,950 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $47,180 for the lowest 10% to over $96,730 for the top 10%. Pay rises with experience, specialty, and employer.

Which companies hire diesel technicians in California?

Employers hiring diesel technicians in California right now include Hub, Diamond Environmental Services, and Penske Truck Leasing, based on current listings on Migrate Mate as of June 2026. California's size and mix of freight corridors, public transit agencies, and agricultural equipment fleets means hiring is distributed across the state rather than concentrated with just a few names.

Which California cities have the most diesel technician jobs?

Stockton, Bloomington, and Yuba City have the most diesel technician openings in California right now. Los Angeles and the Inland Empire dominate because of the Port of Los Angeles and Port of Long Beach freight ecosystem along with the dense concentration of regional trucking hubs, while Sacramento draws demand from state fleet operations and Central Valley logistics activity.

Are there remote diesel technician jobs in California?

Yes, but they're rare. Diesel technician work is fundamentally hands-on and performed at a shop, yard, or job site, so most roles require full on-site presence. About 0% of diesel technician openings tied to California are remote or hybrid as of June 2026, and those positions typically involve remote diagnostics support, technical training, or fleet service coordination rather than bench repair work.

How can I get hired as a diesel technician in California with little or no experience?

The most realistic entry point is a lube technician or shop helper role at a fleet maintenance facility or truck dealership, where you learn under journeyman technicians while working toward ASE certification. Large California employers like Penske and Ryder run structured entry-level technician programs that accept candidates from diesel technology programs at California community colleges without prior shop experience. Completing even one ASE certification before applying, combined with your own basic hand tools, makes a meaningful difference in getting that first offer.

Where can I find and apply to diesel technician jobs in California?

You can find and apply to diesel technician jobs in California on Migrate Mate, which lists current openings across the state. Find roles that fit your experience level and location and apply directly to the employers posting them.
