What are the responsibilities and job description for the Field Service Technician position at Aegis Manufacturing & Engineering?

About the Opportunity

Join a long-standing manufacturer of fluid heating equipment, serving customers across diverse industries worldwide. This role is ideal for a technician who enjoys hands-on electrical/mechanical work, thrives in the field, and wants to build specialized expertise in industrial combustion, controls, and system commissioning.

The company is willing to train strong troubleshooters, making this a great career-building opportunity for someone with solid technical fundamentals looking to step into a high-demand niche.

What You’ll Do

  • Commission new steam and thermal fluid heating units at customer sites
  • Perform electrical and mechanical troubleshooting on industrial systems
  • Work with PLC and HMI platforms (Allen-Bradley, Siemens / RSLogix500, etc.)
  • Conduct combustion testing and tune burner fuel-air ratios using analyzers
  • Support customers via phone/email when not traveling
  • Perform pre-shipment burner testing at the factory
  • Document service work, write weekly trip reports, and contribute to instruction manual content
  • Travel to customer sites including power plants, hospitals, process facilities, boiler rooms, ship engine rooms, labs, and more

Location: Anywhere in the U.S. (must live within 2 hours of a major airport)

Travel: 80–90% (70% domestic / up to 20% international)

Pay: $40–$45/hr Per Diem ($65 domestic / $100–$150 international)

Overtime: could be up to 20 hours during travel weeks

What We’re Looking For

Preferred Background:

  • Associate’s degree or high school diploma/GED
  • 3 years working with PLCs, HMIs, or industrial control systems
  • Experience writing, editing, loading, or troubleshooting control programs (RSLogix500 preferred)
  • Strong electrical & mechanical troubleshooting skills (motors, relays, sensors, actuators, circuits)
  • Ability to read electrical and piping schematics
  • Familiarity with hydraulic and pneumatic systems
  • Experience with boilers, burners, HVAC, or combustion equipment (strong plus)
  • Comfort using hand tools, multimeters, diagnostic equipment, and combustion analyzers

Personal Traits:

  • Enjoys heavy travel and field-based work
  • Strong communicator, both written and verbal
  • Independent, resourceful, and able to represent the company professionally on-site

Why This Role Stands Out

  • Extensive training for candidates with strong troubleshooting skills
  • High autonomy with the ability to work from home when not traveling
  • Exposure to international environments and complex industrial systems
  • Hands-on impact commissioning equipment at customer locations
  • Career-building technical depth in combustion, controls, and industrial heating
