GC Support LLC Traffic Control Supervisor Nashville, TN · Full time Company website

GC Support LLC is a Nashville-based traffic control company serving utility, construction, and roadwork clients across Middle Tennessee. We’re looking for a Working Traffic Control Supervisor to lead our field operations — someone who can flag a lane closure in the morning and dispatch a crew by afternoon. This is a hands-on leadership role, not a desk job. You’ll be the face of GC Support in the field, the point of contact for our clients on-site, and the person our crew looks to for direction, training, and accountability. This role is ideal for an experienced flagger or TCS who’s ready to step into a supervisory position, or a current supervisor looking for ownership-track opportunity at a growing company.

About GC Support LLC

We’re a small, growing traffic control company that does things right. We’re not a revolving door — we invest in our people, we maintain our equipment, and we build real relationships with our clients. This isn’t a position where you’ll be a number. You’ll have direct input into how we operate, how we grow, and where this company goes. If you want to be part of building something from the ground up with people who take the work seriously, we want to talk to you.

Crew Management

  • Supervise a crew of 2–6 flaggers and traffic control technicians on active job sites
  • Onboard new crew members: safety orientation, equipment training, company standards
