Job Description

About the Opportunity

RSCS and MRC are looking for experienced ammonia refrigeration service technicians who know the trade, take pride in their work, and can perform in the field when customers are counting on them. This role is for skilled industrial refrigeration professionals with real ammonia field-service experience - technicians who can walk into an engine room, troubleshoot the issue, communicate clearly with the customer, and help get critical systems operating safely and reliably again. You will join a team of trade professionals who understand industrial refrigeration, value strong workmanship, and support one another across a growing Western U.S. service footprint.

Compensation

We use a tiered hourly pay scale across RSCS and MRC for technician roles: Apprentice/Entry $20-$30, Technician (Early-Career) $30-$40, Journeyman (Mid-Level) $40-$50, and Senior/Field Supervisor $50-$70 (top end reserved for highest-level Senior Ammonia Technicians and Field Supervisors). Starting pay is based on verified experience, certifications, and job scope (including on-call/travel as applicable) and may vary by location due to local market and cost of living; hiring managers set the final starting rate within the appropriate tier. We also offer a robust benefits package.

What We're Looking For

• Hands-on experience with ammonia refrigeration systems required
• Strong troubleshooting skills and safe work habits
• Ability to work independently in the field while contributing to a professional team
• Experience with compressors, controls, valves, motors, electrical troubleshooting, and system startups strongly preferred
• RETA CARO/CIRO, OSHA, EPA Universal, welding, controls, or electrical experience are valued, but practical field skill matters most
• Valid driver's license and willingness to travel and participate in on-call service as needed
• Top industry pay for proven ammonia experience
• Company truck and fuel card
• 100% paid employee medical coverage after 90 days
• Dependent coverage available after one year
