HVAC Commissioning & Service Engineer – Field Diagnostics

Remotely
Full-time

We are an independent engineering consultancy dedicated to elevating indoor environmental quality while reducing lifecycle operating costs. Our multidisciplinary staff pioneers data-driven commissioning strategies for healthcare campuses, biotech labs, high-rise offices, and mission-critical facilities. The culture prizes continuous learning, inventive problem solving, and respectful collaboration—you contribute ideas, not just labor. Though field presence remains vital, we invest in secure remote-monitoring platforms that let our engineers analyze trends, draft reports, and meet clients from any location when site work is complete.  


Responsibilities  

- Perform end-to-end commissioning of air-handling units, chillers, pumps, VAVs, VRF systems, and associated controls.  

- Direct, observe, and validate Testing – Adjusting – Balancing activities; confirm air and hydronic flows meet design intent.  

- Verify building automation sequences, alarms, trend logs, and setpoints through BAS interfaces and data loggers.  

- Conduct diagnostic field investigations using thermal imagers, manometers, and multimeters; isolate failures swiftly.  

- Lead root-cause analysis sessions; craft actionable remediation plans that prevent recurrence and elevate uptime.  

- Develop commissioning plans, pre-functional checklists, and safety procedures in line with ASHRAE Guideline 0 and OSHA LOTO.  

- Produce meticulous service and commissioning reports—clear narratives, annotated photos, multi-variable graphs.  

- Collaborate with mechanical contractors, facility managers, and energy consultants to optimize system performance.  

- Present findings to non-technical stakeholders; translate technical jargon into decisive business insights.  

- Mentor junior technicians on diagnostic techniques, instrumentation, and documentation best practices.  

- Stay abreast of emerging HVAC technologies, retro-commissioning trends, and regulatory updates (IECC, NFPA 90A).  

- Travel to client sites across the U.S.; leverage remote BAS access when feasible to expedite issue resolution.  


Requirements  

- Bachelor’s in Mechanical Engineering, Building Science, or related discipline—equivalent field experience welcomed.  

- 5+ years hands-on HVAC commissioning or service engineering within commercial or institutional facilities.  

- Mastery of airflow measurement, hydronic balancing, data logging, and functional testing methodologies.  

- Solid grasp of control theory, PID tuning, networked BAS protocols (BACnet, Modbus, LonWorks).  

- Demonstrated aptitude for root-cause diagnostics and corrective action development.  

- Proficient with TAB instruments, thermal imaging cameras, power analyzers, and cloud-based analytics dashboards.  

- Exceptional technical writing—reports withstand legal scrutiny and support utility incentive claims.  

- Working knowledge of energy-code compliance, LEED Fundamental/Enhanced Cx, and retro-commissioning standards.  

- Safety-first mindset; practiced in LOTO, confined-space entry, and PPE selection.  

- Valid driver’s license and ability to travel up to 40 %—occasionally on short notice.  


Preferred Extras  

- Certification: CxA, BCxP, NEBB, TABB, or equivalent.  

- Experience with net-zero energy design, thermal storage systems, or large-scale heat-pump deployment.  

- Familiarity with cybersecurity requirements for smart-building networks.
