HR Director

Mainline Services is a growing, privately held company serving the railroad, transportation, construction, and industrial markets. Our work is operationally driven, customer-focused, and often performed in demanding field environments where safety, responsiveness, and teamwork are critical. As Mainline continues to grow, we are investing in the people, processes, and infrastructure needed to support that growth. We are looking for an HR leader who wants to be part of building that foundation, not simply maintaining an existing HR function. At Mainline, HR is closely connected to the business.
