• Assist with PLC I/O checkout, point-to-point wire verification, and basic troubleshooting of control circuits

• Support hardware-in-the-loop testing, commissioning, and factory/site acceptance testing alongside engineers

• Perform ground ops support at ATP and customer sites: rigging, equipment moves, staging, and field installation

• Identify and flag build issues, fit-up problems, and wiring discrepancies before they become integration problems

• Maintain a clean, organized, and safe shop and field work environment

• Keep build records, punch lists, and as-built documentation accurate and up to date

• Travel to ATP sites, customer locations, and vendor facilities as needed

Required Qualifications

• High school diploma or equivalent; technical/trade school training a plus

• Comfortable using hand tools, power tools, and basic shop/fab equipment

• Ability to work hands‑on in laboratory, fabrication, and plant environments

• Strong attention to detail and follow‑through on build quality

• Ability to work on‑site and travel as needed

Preferred Qualifications

• Experience with 480 VAC / 24 VDC industrial control panel wiring

• Experience assembling fluid/process systems, tubing, or piping

• Exposure to Siemens or similar PLC platforms

• Experience with skidded/modular equipment builds

• Experience in defense, aerospace, energetics, or other regulated manufacturing environments

Additional Requirements

• Ability to lift 50 lbs

• U.S. Person and ability to obtain a security clearance
