- Use precision measuring tools including micrometers, calipers, and gauges to evaluate wear, tolerances, and clearances
- Identify worn or damaged areas and make sound repair decisions based on measurements and manufacturer specifications
- Position and align components for assembly using hand tools, power tools, hoists, cranes, and rigging as appropriate
- Set and verify component clearances and confirm parts inventory for active jobs
- Operate and maintain shop equipment including hot tanks, blasting units, forklifts, cranes, hoists, and power tools
- Support loading, unloading, packaging, inventory, shop organization, facility upkeep, and other production-support activities as needed
- Follow all PPE, safety, housekeeping, environmental, and equipment-handling requirements
Must-Have Skills, Experience, and Education
- Professional hands-on experience with automotive, commercial, diesel, heavy-equipment, marine, stationary, power-generation, or other reciprocating engines

- Strong attention to detail, safety discipline, and willingness to support general shop and production needs
Nice-to-Have Skills
- Direct experience rebuilding large reciprocating or stationary power-generation engines
- GE Jenbacher engine experience; Deutz/MWM, CAT, MAN, or comparable industrial engine experience also transfers well
- Diesel mechanic, heavy-equipment mechanic, marine-engine, power-generation, or power-technology background
- Experience rebuilding cylinder heads, pumps, intercoolers, connecting rods, or similar engine components
- Welding, machining, rigging, forklift, crane, or hoist experience
- Formal technical training in diesel technology, marine engineering, automotive technology, power generation, or a related trade
- Military technical experience such as Navy MM, EN, GSM/GSE, MR; Army 91B, 91L, 91D; Air Force 2A6X1 or 3E0X2; Marine 1341 or similar diesel/mechanical specialties; or Coast Guard MK
- Steam, nuclear, gas-turbine, marine, or other military engineering-plant experience with strong hands-on mechanical capability
