Industrial Refrigeration Technician (Ammonia/R717)

Location: Sunset Hills, MO

Travel: Primarily domestic. Expect up to ~120 days/year
; trips are typically 5–12 days (overall range 3–15; may include weekends when timelines require). 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.

What you’ll do

  • Install & commission ammonia refrigeration systems: mechanical fit-up, charge, verify safeties, tune setpoints, and complete turnover documentation.
  • 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 $40-60/hr 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).
