The company arranges flights, hotels, and cars; expenses are covered; tools/parts pre-staged or shipped. Travel is paid (separate travel vs. on-site rates), with overtime at time-and-a-half.

Make an impact on real production. This role supports high-volume industrial ice manufacturing, packaging, and palletizing systems powered by ammonia refrigeration. You’ll be the hands-on professional who commissions new lines, troubleshoots problems, and trains plant staff to operate safely and efficiently.

• Troubleshoot & optimize refrigeration (compressors, recirculators, evaporators, condensers, purgers, valves), electrical (3-phase, VFDs, sensors), and PLC I/O—on-site and remote.
• Lead with safety: LOTO, gas detection, ventilation, PPE; familiarity with IIAR/PSM a plus.
• Partner with customers: Train operators, document clearly, and recommend upgrades/parts.
• Support the team at HQ between trips (phone troubleshooting, parts/bench work, project prep).

What you bring

• Proven ammonia industrial refrigeration experience.
• Strong electrical/mechanical fundamentals and ability to read P&IDs/schematics.
• PLC exposure for startups/basic troubleshooting.
• Clear communicator and steady problem solver.
• Certifications: EPA 608 required; RETA CARO/CIRO and IIAR familiarity preferred.
• Willingness to travel as outlined; passport helpful.

Why this role

• Mentorship & backup: Pair with senior techs; 35-year engineer provides remote support.
• Training: OEM factory classes + distributor-led training.
• Culture: Family-oriented leadership that prioritizes weekend home time.
• Compensation: Hourly + OT, with typical W-2s in the $75k–$100k range.
• Benefits: 401(k) with 4% match; medical coverage with company-paid share; HSA seed; 3 weeks PTO from day one (4 weeks after 5 years).
