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 own

• Lead first-shift machining operations for approximately 15–20 employees, including about 3–5 leads/co-leads.
• Recruit, train, evaluate, coach, and develop machining talent.
• Drive safety, quality, productivity, staffing balance, machine utilization, and output.
• Continuously improve equipment, tooling, process flow, staffing plans, and work methods.
• Sustain 6S and champion Lean and continuous-improvement initiatives.
• Expand workforce flexibility through structured cross-training.
• Prepare labor forecasts, productivity metrics, cost reports, and staffing models.
• Partner with Manufacturing Engineering to build and maintain SOPs and production procedures.
• Manage departmental budgets and coordinate shared resources across teams.
• Support AS9100, safety, environmental, customer-quality, and audit/compliance requirements.

Collaboration

You’ll work shoulder-to-shoulder with Quality, CNC Programming, Manufacturing Engineering, skilled machinists, and tooling/equipment suppliers to troubleshoot issues, validate processes, and keep production on track.

Required experience & skills

• ~10 years of hands-on CNC machining experience.
• 5–10 years leading machining teams, overseeing a substantial CNC operation (beyond a small shop).
• Expert blueprint reading and advanced GD&T comprehension (tolerances, datums, geometric controls, inspection interpretation, and print conformance).
• Deep knowledge of CNC equipment, tooling, setups, machine capabilities, processes, and troubleshooting.
• Strong technical problem-solving with cross-functional collaboration.
• Proven coaching, mentoring, cross-training, and team development skills; experience using progressive discipline when needed.
• Proficiency with micrometers, calipers, and precision instruments; able to train others.
• Ability to interpret CMM data and make sound production/quality/process decisions.
• Capability assessments for equipment and processes to ensure parts meet specification.

Preferred qualifications

• Background in aerospace or similarly complex precision machining.
• Lathe experience, especially on Mazak Integrex or other multi-task platforms.
• Technical or trade-school education; technical foundation plus business education is a plus.
• OSHA 10/30 or practical EHS team experience.
• Strong Microsoft Office skills and fluency with ERP/MRP systems.

Leadership style we value

• Coach, mentor, and develop current and future leaders.
• Hold people accountable while removing roadblocks and addressing root causes.
• Stay calm, respectful, and professional in tough conversations.
• Invest in developing machinists, leads, and co-leads for what’s next.
• Embrace change, growth, Lean, 6S, continuous improvement, and innovation.
• Thrive in a hands-on, privately held, rapidly growing manufacturing setting.

Our machining environment

• About 65 CNC machines at our St. Peters site and roughly 90 company-wide.
• Occasional collaboration with another facility on part transfers, capabilities, and processes.
• Very limited travel.
• Little to no direct customer interaction.

Benefits

• 96 hours of PTO in the first year, accruing from day one.
• Nine paid holidays plus a paid anniversary day.
• Health, dental, and vision insurance.
• Voluntary life and basic life insurance.
• AD&D and EAP.
• Short-term and long-term disability.
• Parental leave and Teladoc services.
• 401(k) match: 100% on the first 3% contributed, plus 50% on the next 2%.
