Commissioning Engineer, Boiler & HVAC Systems

Location: NYC & Westchester County, NY (field-based, in-person)

Job Type: Full-time, in-person

Industry: Commercial Mechanical Contracting, Heating Systems Installation and Commissioning

A licensed Master Plumber and General Contractor serving NYC and Westchester is hiring a Commissioning Engineer to own startup and commissioning on its new mechanical installations, from pre-startup readiness through first fire and verified operation. Because the company self-performs its installation work, you carry that engineering all the way through to a signed-off, documented retrofit. This is a hands-on role in the mechanical room, not a desk job, with a company that's grown from 20 to over 100 employees on a deep, growing installation pipeline.

Responsibilities

• Build the commissioning plan for each installed system during technical review, including functional tests, KPIs, and required data
• Review schematics and the Sequence of Operations for HVAC, steam, hydronic, and domestic hot water systems, and raise RFIs before installation
• Walk installations near completion of the plumbing scope to confirm hardware, sensors, and wiring are installed and ready for startup
• Own the go/no-go call on startup readiness and manage the punch list until the site is ready
• Energize and start boilers, pumps, and controls, confirming proper operation of all inputs and outputs
• Run combustion analysis on a calibrated analyzer, recording O2, CO, stack temperature, and combustion efficiency across the firing range
• Verify safeties and interlocks, including LWCO, high-limit, gas pressure switches, flame safeguard, and proof-of-closure
• Troubleshoot line- and low-voltage control circuits and set up long-term test instrumentation for the commissioning phase
• Prove system sequencing, staging, and controls, including the company's proprietary building automation platform, perform per design (lead/lag rotation, modulation, setback/changeover schedules)
• Produce Commissioning Reports and Boiler Room Settings documentation for the owner and service team

Required Qualifications

• Bachelor's degree in Mechanical Engineering strongly preferred, or equivalent hands-on heating systems experience
• 4+ years of hands-on experience with commercial boilers, burners, pumps, and controls
• Working knowledge of NYC steam and hydronic heating systems
• Comfortable working hands-on in an active mechanical room
• Ability to read mechanical schematics, wiring diagrams, and a written Sequence of Operations
• Strong written communication skills for owner- and service-facing reports
• Valid driver's license and ability to travel to job sites across NYC and Westchester
• OSHA SST certification

Preferred

• 3+ years of startup and commissioning experience on boiler or heating-plant installations
• Understanding of combustion analysis and optimization
• Familiarity with building automation systems (BAS) and remote-monitoring platforms
• Knowledge of Local Law 87 and Local Law 97 retro-commissioning and reporting requirements

Compensation and Benefits

• $125,000 - $140,000 base salary, commensurate with experience, plus incentive compensation
• 401(k) with company match
• Health, dental, and vision insurance
• HSA and FSA
• Life insurance
• Paid time off and parental leave
