Diesel Service Technician Jobs in Texas: Frequently Asked Questions

How do you become a diesel service technician in Texas?

Texas does not require a state-issued license to work as a diesel service technician, so most employers hire based on certifications and hands-on experience. The clearest path is completing a diesel technology program at a Texas community college such as Houston Community College, San Jacinto College, or Texas State Technical College, then pursuing ASE certification in medium and heavy trucks. Employers across the state consistently treat ASE credentials as the primary hiring benchmark.

How much do diesel service technicians make in Texas?

Diesel service technicians in Texas earn a median of about $58,810 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $40,930 for the lowest 10% to over $81,660 for the top 10%. Pay rises with experience, specialty, and employer.

Which companies hire diesel service technicians in Texas?

Employers hiring diesel service technicians in Texas right now include Cummins, Republic Services, and SelecTransportation Resources, based on current listings on Migrate Mate as of June 2026. Texas's dense commercial freight corridors and active oil and gas sector mean large fleet operators and equipment dealers maintain some of the highest and most consistent technician headcounts in the country.

Which Texas cities have the most diesel service technician jobs?

Dallas, Harlingen, and Lewisville have the most diesel service technician openings in Texas. Houston's volume is driven by its role as the national center for energy and heavy equipment logistics, Dallas-Fort Worth by one of the largest freight and distribution networks in the southern United States, and San Antonio by its military installation support contracts and growing commercial fleet infrastructure.

Are there remote diesel service technician jobs in Texas?

Yes, but they're rare. Diesel service technician work is fundamentally hands-on and tied to a physical shop, fleet yard, or job site, which limits remote options. About 13% of diesel service technician openings tied to Texas are remote or hybrid as of June 2026, and those positions typically involve technical support, warranty claims, or service writing rather than direct repair work.

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

The most realistic entry path is enrolling in a diesel technology program at Texas State Technical College, San Jacinto College, or a similar Texas institution that offers employer partnerships and hands-on lab time. Large Texas fleet operators like Ryder and Rush Enterprises regularly hire lube technicians, service assistants, and tire technicians as feeder roles that transition into full diesel tech positions. Earning even one ASE student certification before applying gives candidates a measurable edge in entry-level screening.

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

You can find and apply to diesel service technician jobs in Texas on Migrate Mate, which lists current openings tied to Texas employers. Search the listings, find roles that match your experience and location, and apply directly to the ones that fit.
