What we’re looking for

• We are looking for an experienced mechanic who takes pride in keeping equipment running and who understands that proper diagnosis is just as important as the repair itself.

• Welding and fabrication skills a plus.
• CDL is a plus.

• Mechanics handle tools and parts and use lifting equipment or assistance for heavy components.
• Work is primarily in the shop, with occasional field repairs outdoors in varying weather.
• The role involves exposure to shop noise, dust, diesel exhaust, oils, and grease. Required protective equipment must be worn.
