• Select components (pistons, rods, bearings, camshafts, gaskets, fasteners) to match build goals and duty cycle.

• Precisely assemble short blocks and long blocks per OEM specs or custom performance targets.

• Set timing, verify oiling, prime systems, and perform pre-start checks.

• Support testing and tuning (break‑in procedures, leakdown/compression, data collection) and address issues.

• Maintain tools, calibration, cleanliness, and build records for traceability and quality.

• Follow all safety procedures while working around vehicles, lifts, hoists, chemicals, and rotating machinery.

• Proven, hands-on engine teardown and assembly experience in automotive or performance environments.

• Strong knowledge of internal combustion fundamentals and failure modes.

• Proficient with precision tools: micrometers, bore gauges, dial indicators, torque/angle tools, plastigage.

• Ability to read specs, drawings, and service information; complete build sheets accurately.

• Organized, detail‑oriented, and quality‑driven; able to work independently and in a team.

• Valid driver’s license; ability to safely move vehicles and lift up to 50 lbs as needed.

• Performance/racing engine experience (NA, boosted, E85, flex, towing/heavy‑duty).

• Cylinder head work (valve/seat cutting, spring setup), balancing, and ring filing.

• Familiarity with dyno operations, data acquisition, and break‑in/tuning workflows.

• ASE certifications, trade school, or equivalent technical training.

• Basic welding/fabrication or CNC/manual machining exposure a plus.

• Competitive compensation with opportunities for overtime and advancement.

• Growth and training in a fast‑paced, innovative environment.

• Modern equipment, clean workspaces, and diverse projects (OEM, motorsports, specialty).

• Benefits package and paid time off/holidays.
