You'll be responsible for load calculations, field investigation, system assessments, and detailed mechanical design.

This role offers the opportunity to work on some of NYC's most iconic and complex buildings-balancing practical solutions with high-performance design goals.

We are looking for passionate, driven individuals to join our team focused on Delivering Solutions and Improving Lives.

Responsibilities

• Perform field assessments of existing mechanical systems, including steam distribution, hydronic systems, airside equipment, and controls—often in buildings with incomplete or 40+ year-old documentation.
• Interpret and update legacy mechanical drawings and system schematics.
• Conduct HVAC load calculations using Carrier HAP, with a strong understanding of building diversity and NYC climate profiles.
• Design HVAC and steam system upgrades for high-rise buildings, including central plant, boiler plants, and terminal unit integration.

Qualifications

• 4-10 years of relevant experience in MEP consulting or building systems engineering.
• Strong working knowledge of steam, chilled water, hot water, and air distribution system design.
• Experience working on high-rise residential, commercial, or mixed-use buildings, preferably in New York City.
• Proficiency with AutoCAD (required), Revit (preferred), and Carrier HAP (or similar load calc tools).
• Familiarity with reviewing and modifying older building documentation.
• Strong knowledge of ASHRAE, IECC, and NYC-specific codes and standards.
• Ability to work in the field, on foot.

Preferred Qualifications:

• PE license (NY/CT/NJ preferred) or active progress toward licensure.
• Experience with building decarbonization and compliance strategies under NYC's climate legislation.
• Knowledge of controls optimization, sequences of operation, and BAS upgrades
