Job description

About the Role

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.

What You'll Do

Field Operations

• Set up and manage work zone traffic control in compliance with the MUTCD and Tennessee DOT standards
• Flag and operate traffic control devices (signs, cones, arrow boards, barricades) alongside the crew
• Conduct daily site inspections and ensure proper setup before work begins
• Monitor and adjust traffic control plans based on changing road and weather conditions
• Serve as the primary on-site point of contact for clients, contractors, and utility crews
• Respond to and resolve field issues - equipment failures, traffic conflicts, safety concerns - in real time

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
• Conduct daily safety briefings and enforce PPE and work zone safety compliance
• Handle scheduling, no-shoes, and crew changes - step in and flag when needed
• Provide real-time coaching and performance feedback in the field
• Document crew hours, job completion, and any incidents or near-misses

Operations Support

• Coordinate daily job assignments and dispatch with ownership
• Ensure trucks, arrow boards, and equipment are maintained, fueled, and job-ready
• Complete daily job reports, time tracking, and client sign-offs
• Manage inventory of traffic control devices and flag supply needs before they become problems
• Communicate proactively with ownership about job status, client feedback, and crew performance

What We're Looking For

Required

• 2 years of experience in traffic control, road construction, or utility work zone operations
• ATSSA Traffic Control Supervisor (TCS) certification, or ability to obtain within 90 days of hire
• Valid Tennessee driver's license with clean driving record
• Ability to set up and manage a work zone independently, including reading and executing traffic control plans
• Comfortable working outdoors in all weather conditions, standing for extended periods, and lifting 50 lbs
• Reliable - this role requires showing up every day, on time, ready to work
• Strong communication skills with crew, clients, and contractors

Preferred

• Experience supervising field crews in traffic control or construction
• OSHA 10 or OSHA 30 certification
• CDL or ability to operate trucks with mounted arrow boards and attenuators
• Familiarity with TDOT work zone standards and permitting
• Bilingual (English/Spanish) is a plus
