• Coordinate with architects, electrical, plumbing, and fire protection engineers, equipment vendors, and contractors.
• Apply relevant building, mechanical, and energy codes and industry standards.
• Review contractor submittals and shop drawings for conformance with design intent; respond to RFIs and conduct construction site observations.
• Delegate work to junior engineers, provide clear direction, and review their work throughout the design process.
• Manage mechanical design scope, schedules, and budgets across multiple projects.
• Contribute to department standards, quality reviews, and staff development.

Qualifications

• Bachelor’s degree in Mechanical Engineering or a related field.
• 9+ years of HVAC design experience within the building industry.
• Professional Engineer (PE) license preferred.
• Experience developing coordinated HVAC construction documents.
• Proficiency in Revit and familiarity with HVAC load calculation and equipment selection software.
