Combustion Engineer Jobs in Arizona (NOW HIRING)

We are hiring a Boiler Controls Technician to cover the greater Phoenix market and the surrounding territory. This is a field role — you will spend your days in boiler rooms, mechanical spaces, and plant floors across a mix of manufacturing, food and beverage, healthcare, higher education, and commercial accounts. You will be the technical authority on burner management systems, combustion controls, and the instrumentation that keeps industrial steam and hot water equipment running safely and efficiently. Most days you will work independently, make your own calls, and own the outcome. The company backs you with the training, tooling, and factory relationships to do that well.

• Troubleshooting, repairing, and commissioning burner management systems and flame safeguard controls on industrial firetube and watertube boilers.

• Performing combustion tuning and analysis — setting linkage or parallel positioning, dialing in fuel/air ratios, verifying O2 trim, and documenting results against efficiency and emissions targets.

• Diagnosing and programming PLC- and HMI-based control systems, including modulating controls, feedwater and level controls, draft controls, and lead/lag sequencing.

• Executing controls retrofits and upgrades — replacing obsolete flame safeguard, converting linkage systems to parallel positioning, and integrating new instrumentation into existing plant systems.

• Conducting startups and commissioning on new equipment installations, including loop checks, functional testing, and safety interlock verification.

• Responding to emergency service calls within the territory and participating in a shared on-call rotation.

• Writing clear, defensible service documentation — what failed, what you did, what the customer should plan for next.

• Advising customers directly on reliability, efficiency, and code compliance, and flagging legitimate opportunities for the sales and project teams.

Requirements

The non-negotiable is real controls depth on industrial equipment. Commercial and residential boiler experience is a different animal, and this role is not the place to learn the difference on a customer's dime.

• Three to five years of hands-on experience in boiler controls, combustion controls, or burner service on industrial boilers.

• Working command of flame safeguard and burner management platforms — Honeywell, Fireye, Siemens, Autoflame, Preferred Instruments, or comparable systems.

• Solid electrical troubleshooting ability: reading ladder logic and schematics, using a multimeter with intent, and tracing a fault through a control panel without guessing.

• Familiarity with combustion analyzers and the judgment to interpret what they are telling you.

• Comfort working around gas trains, high-pressure steam, and energized equipment, with the safety discipline that comes with it.

• Customer-facing professionalism — you will be the face of the company in the boiler room, often in front of a plant manager who is having a bad day.

• Valid driver's license and a clean motor vehicle record.

• Willingness to travel within the territory and participate in on-call rotation.

• Low NOx burner experience and familiarity with local emissions requirements.

• PLC programming experience — Allen-Bradley, Siemens, or similar.

• Experience with parallel positioning conversions and O2 trim system installations.

• Boiler operator license, NICET certification, or manufacturer-specific factory training.

• Background in a dealer, OEM, or independent boiler service organization.

Benefits

The target range is $55 to $65 per hour, depending on depth of controls experience and platform familiarity. Overtime is paid and is a real part of the earnings picture in this role — the strongest technicians on this team clear well above their base rate over the course of a year. Relocation assistance is available for the right candidate, so if you are the technician we are describing and you are not in Arizona today, that is a solvable problem.
