- Execute high-value Local Law 87 retro-commissioning projects and ASHRAE-aligned commissioning activities, ensuring rigorous quality standards beyond basic compliance checking.
- Build strong, professional working relationships with chief engineers, building operators, facility managers, and client teams to ensure seamless execution on site.
- Contribute to improving internal processes, leveraging data tools, and expanding technical efficiency in field data collection and analysis.
Requirements
- Bachelor’s degree in Mechanical Engineering or a related discipline.
- 5–10 years of hands-on experience in commissioning, retro-commissioning (RCx), or mechanical energy engineering.
- Deep working knowledge of HVAC systems, central plants, controls, and ASHRAE commissioning guidelines, with a strong focus on large commercial or complex facilities.
- AI proficiency is required.
- Active OSHA 10 certification (or OSHA 30) is required.
- Strong commitment to job site safety and best practices in machine rooms and central mechanical plants.
- Strong interpersonal and communication skills; proven ability to build trust and rapport with chief engineers, union operators, and building managers in high-pressure field environments.
