Patriot Fleet Services is the leading provider of on-site mobile truck repair and fleet maintenance in New England — and we’re hiring experienced Mobile Diesel Technicians who want independence, strong pay, and a company truck they can take home.

If you’re a skilled diesel mechanic who prefers working in the field instead of being stuck in a shop, this is for you.
