Rail MOW Maintainer, Traction Power

Department: Charlotte Area Transit System Department

Salary: $29.71 - $46.42 Commensurate with Experience

Thank you for your interest in joining the team that keeps Charlotte moving, at a very exciting time for our organization. At the Charlotte Area Transit System (CATS), we’re committed to delivering safe, reliable, and innovative transit services for our growing community, and we value employees who bring professionalism, passion, and a commitment to public service.

This position is currently employed by CATS, a department of the City of Charlotte. With the passage of the PAVE Act and last year’s sales tax referendum, CATS is preparing to transition from a City department to the newly created Metropolitan Public Transit Authority (MPTA). The MPTA was established to strengthen regional transit governance, improve accountability, and support long‑term investment in mobility. It’s an important and exciting step forward for transit in our region.

Employees hired into this role will remain City employees through December 31, 2026, and will transition to MPTA employment on January 1, 2027. Benefits and compensation will follow City provisions through 2026 and shift to MPTA provisions in 2027, with clear information shared in advance. Your core duties, reporting structure, and daily responsibilities will remain consistent, with no break in service. If anything delays the transition, your City employment, including compensation and benefits, will remain in place until the move to the MPTA occurs.

The creation of the MPTA positions us for a more modern, sustainable, and efficient transit system, one that can better support the Charlotte region for decades to come. We’re excited about what’s ahead and appreciate your interest in being part of it.
