Technical Authority: Develop specifications and enforce high-quality standards, methods, and procedures for design review and inspection across the team.


Problem Solver: Identify, troubleshoot, and implement efficient, novel solutions to complex, non-routine engineering challenges that impact project direction.


Mentorship & Guidance: Act as a direct mentor and technical resource for junior engineers, directing workflow, resolving technical roadblocks, and fostering their professional growth.


What We're Looking For: Expertise & Experience


Experience: 3 years of progressive experience in mechanical design engineering, specifically focused on HVAC systems.


Technical Mastery: Deep expertise in advanced engineering calculations (loads, sizing, hydraulics) and developing comprehensive system specifications.


Leadership Acumen: Proven ability to manage technical aspects of projects, work of others, and effectively resolve complex technical issues.


Education: Bachelor’s degree in Mechanical Engineering or a related field.


Licensure: Engineer-in-Training (EIT) is a plus.
