Role Summary

As Lead Mechanical Designer/Engineer - HVAC, you will serve as the primary technical authority on your project teams - owning HVAC and mechanical system design from concept through construction closeout, mentoring junior staff, and acting as the principal liaison for owners, architects, and trade partners across a diverse portfolio of industrial, healthcare, hospitality, commercial, higher education, laboratory, and multifamily projects. This role offers a clear path to senior leadership as AMC’s Engineering Department continues to grow.

What You’ll Work On

Higher education: mechanical retrofits and new construction on university campuses (e.g., University of St. Thomas - Owens Science Hall).
Laboratory & scientific: fume hood systems, exhaust/makeup air, and precise environmental controls (e.g., Hormel Institute - Microscope laboratory conversion).
Large-scale multifamily: high-rise design-build including complex rooftop equipment logistics (e.g., Portland & Washington - 22-story, 240-unit tower).

Key Responsibilities

Lead HVAC and mechanical piping system design: system selection, equipment sizing, load calculations, ductwork/piping layouts, and construction document production (Revit, AutoCAD).

Supervise and mentor engineering design staff; provide quality review on all deliverables.
Collaborate with Project Managers on schedule, budget, scope development, equipment selection, and pre-construction pricing.
Partner with VDC, estimators, field superintendents, and purchasing as the engineering subject matter expert throughout the project lifecycle.
Maintain current knowledge of MN Mechanical, Energy, Plumbing, and Fire/NFPA codes; ASHRAE 90.1, 62.1; and SMACNA standards.

Required Qualifications

Associate’s degree or higher in Mechanical Engineering or Engineering Technology - or equivalent combination of education and hands-on experience.
7+ years of progressive HVAC and mechanical systems design experience, including 2+ years in a lead or project-ownership role.
Strong working knowledge of HVAC system types and system selection: packaged equipment, hydronic/pumping, VAV, VRF/refrigeration, make-up air, and controls/BAS.
Proficiency with load calculation software (Trane Trace 700, HAP, IES VE, or equivalent); Revit; AutoCAD; Bluebeam Revu; Autodesk Forma; and Microsoft 365.
Demonstrated experience leading construction phase services: submittals, RFIs, change orders, and field coordination.
