About Us

Sigma Commercial LLC is a Milwaukee-based holding company overseeing four operating businesses: LaBonte Construction (luxury residential remodeling), Property Prep (commercial maintenance and janitorial), Vandelay Group (residential property management), and Sigma Commercial itself (shared back office). We're a small, hands-on team - people wear multiple hats and things get done without a lot of red tape.

The Role

This is a solo HR seat covering our group - no team, no direct reports, just you owning recruiting, payroll, and benefits end to end. Most of your week is recruiting: filling construction and maintenance crews with people who actually show up and do the work. The rest is running payroll accurately and keeping our benefits and insurance programs compliant.
