Mechanical Engineer

Millig Design Build is seeking a Mechanical Engineer to design HVAC systems in ground-up and retrofit situations, support decarbonization planning and design, and develop facility improvement projects within our fully integrated team.

This candidate will have the opportunity to join our rapidly growing engineering team of the best engineers in the country in designing systems to make buildings healthier, safer, and more energy efficient. Our clients include major universities, international manufacturers, state governments, counties, and school districts.
