About the Role

We’re looking for a Mechanical Design Engineer / Account Executive to support our growing tenant improvement (TI) and special projects work.

  • Estimate projects and prepare proposals
  • Help manage projects after the sale in coordination with operations
What We’re Looking For
  • Background in Mechanical Engineering or HVAC design (degree or equivalent experience)
  • Experience with commercial HVAC systems (TI/retrofit work is a plus)
  • Ability to create HVAC drawings and layouts independently
  • Comfortable working directly with customers
  • Proficiency in AutoCAD, Bluebeam, and Microsoft Office
Why Join Us
  • Strong pipeline of repeat TI and special project work
  • Opportunity to own your projects from start to finish
  • Stable, established commercial HVAC contractor
  • Full-Time | Salary + Bonus
What We Offer
  • Competitive base salary plus performance-based incentives
  • Company vehicle or vehicle allowance (if applicable)
  • Health, dental, and vision insurance
  • 401K with match
