CNC Machining Operations Supervisor

A day in the life

As the CNC Machining Operations Supervisor, you open the first shift with a safety huddle and a quick 6S walk-through. You review machine status across a busy floor, prioritize work with 3–5 leads, and set the pace for a team of roughly 15–20 machinists. Before lunch, you’ve partnered with Quality to disposition an inspection finding, synced with CNC Programming and Manufacturing Engineering on an SOP update, and spoken with a tooling vendor about a new insert to improve cycle time.

By day’s end, you’ve coached a developing lead, approved staffing plans, and aligned budgets with production targets—while keeping safety, quality, and delivery front and center.

What you’ll ownLead first-shift machining operations for approximately 15–20 employees, including about 3–5 leads/co-leads.
