Design Assistant

Dave Jones is a Wisconsin-based mechanical contracting firm that has been delivering plumbing, HVAC, fire protection, and electrical services to commercial clients for decades. We’re proud of the work we do — and even prouder of the people we do it with.

We believe that a team with a great culture and great people will always find a way to win. That starts with investing in our people — from day one and every step of the way. If you’re looking for a place to grow your technical skills, contribute to real commercial projects, and work alongside people who genuinely care about each other, we’d love to have you on the team.

Our goal is to be a company that our people, customers, partners, and communities are proud to be part of.

The Opportunity

You’ll work directly alongside experienced HVAC designers, contributing to the full lifecycle of commercial projects while continuing to develop your technical depth. This is a role with a clear path forward for the right person.
