Job Description

Field Service Technician

CES keeps customers compressed‑air systems running, and the field service technician is the person who makes that real. You’re in the field every day — performing preventive maintenance, diagnosing and repairing compressors, dryers, and air‑system equipment, and responding when a customer goes down. The techs are the face of CES, and the service you deliver is what earns the next agreement.

What you’ll do

• Perform scheduled preventive maintenance on air compressors — rotary screw, reciprocating, and oil‑free — along with dryers, filters, controls, and related air‑system equipment.
• Diagnose and repair mechanical, electrical, and air‑system problems in the field, and respond to reactive and emergency service calls.
• Install and commission compressors, dryers, piping, and ancillary equipment.
• Use a phone or tablet to document each visit — before‑and‑after photos, work performed, parts used, and recommendations — and clearly explain to the customer what was done and what’s coming next.
• Spot additional needs — leaks, pressure drops, failing components — and flag them so they become the next job.
• Keep your service vehicle, tools, and parts stocked and ready.
• Follow all safety procedures and maintain a strong safety record.

The team behind you

You won’t be out there alone. CES has a lead technician and trainer to bring you up to speed, an applications and engineering team for system sizing and the tougher technical calls, and a coordinator handling scheduling and parts so you can stay focus on the work. We believe in developing our people toward their own goals — whatever direction you want to grow, we’ll help you build the skills to get there.

What we’re looking for

• Hands‑on experience servicing compressed‑air systems, industrial machinery, HVAC, or comparable mechanical equipment.
• Solid mechanical and electrical troubleshooting — comfortable with hand tools, gauges, and diagnostics.
• Able to read schematics and equipment manuals.
• Valid driver’s license and a clean driving record — you’re in the field every day.
• Able to lift and move equipment and work in plant and mechanical‑room environments.
