Diesel Power & Hydraulic Systems Field Mechanic Build What Keeps Industries Moving

Every pump that spins, every cylinder that extends, every diesel engine that roars to life—behind it is a technician who made it happen. Join an established, fast-growing industry leader and become that technician for customers across the St. Louis region.

Your Mission

Own the health of mission-critical mechanical equipment in the field. You’ll combine sharp diagnostics with hands-on skill to keep diesel- and hydraulics-driven systems online and efficient.

Impact You’ll Make

• Diagnose, maintain, and repair equipment at customer sites—with some projects completed in the company shop.
• Service diesel engines; troubleshoot hydraulic systems; work with pumps, motors, bearings, shafts, seals, rotating assemblies, gearboxes, and drive components.
• Apply test methods, inspections, drawings, manuals, and hydraulic schematics to pinpoint faults and determine corrective actions.
• Execute preventive maintenance; identify worn/failed parts; remove, repair, replace, and install components.
• Support equipment startup, functional testing, and commissioning to verify performance.
• Communicate clearly with customers about findings, repairs, and maintenance recommendations; complete all service documentation accurately.
• Operate independently in the field while tapping into technical support when needed.
• Maintain your service vehicle and tooling; uphold company and customer safety standards.

Travel Rhythm

• Field-first role covering St. Louis and nearby territories.
• Travel is mostly regional—most days end at home.
• Occasional overnight trips occur based on project needs.
• This is not a nationwide travel position.

Who Thrives Here

We hire for troubleshooting strength. People from the following paths do especially well:

• Heavy equipment, construction equipment, or equipment rental service
• Diesel technician/mechanic or generator technician
• Field/road/mobile equipment mechanic

What Sets You Apart

• Hands-on experience with diesel-powered machinery and hydraulic systems (pumps, motors, hoses, cylinders, valves).
• Comfort with rotating equipment and complex mechanical systems.
• A root-cause approach—troubleshoot first, then repair.
• Ability to interpret mechanical drawings, service documentation, and hydraulic schematics.
• Field service experience and confidence to work independently at customer locations.
• High mechanical aptitude and practical problem-solving skills.

Familiarity with our exact equipment isn’t required. If you bring strong diesel, hydraulic, heavy equipment, or industrial mechanical experience, we’ll provide targeted training on our systems.

• Competitive compensation
• Comprehensive health benefits: medical, dental, vision
• Retirement benefits
• Paid time off and holidays
• Company-provided tools and/or service equipment
• Ongoing technical training and clear advancement paths
