The organization values growth, measurable performance, and craftsmanship-making this a role for top-tier professionals ready to lead, innovate, and succeed.

What You'll Do

• Operate CNC lathes and milling machines across multiple cells, including tool set-up, inserts, offsets, and deburring finished parts

• Lead corrective and preventive maintenance tasks to minimize downtime and maintain machine performance
• Review production schedules, prioritize shift tasks, prepare materials and equipment for operations
• Troubleshoot complex machining issues, identify root causes, and implement solutions for improved uptime
• Provide hands-on supervision of CNC machinists/operators on 3rd shift, assigning tasks, monitoring progress, and ensuring adherence to quality and productivity goals
• Drive continuous improvement initiatives-develop new fixturing, tooling, and process enhancements to elevate throughput
• Collaborate with engineering, maintenance, and production planning to ensure seamless operations and cross-shift alignment
• Uphold safety, quality, and compliance standards within the CNC environment and broader manufacturing facility

What You Bring

• Minimum of 8 years of hands-on experience operating and setting up CNC lathes and milling machines (horizontal & vertical)
• At least 2 years of experience as a lead machinist or supervisor, preferably on 2nd or 3rd shift
• Proficiency in CNC programming, both Mazatrol and G-code languages
• Ability to read and interpret engineering drawings, schematics, and GD&T
• Skilled in precision measurement and inspection tools; knowledge of SPC and ISO quality systems
• Proven leadership ability - train, coach, mentor, and guide machinists to meet performance and quality goals
• Comfortable working autonomously during off-hours, making rapid decisions to keep production moving
• Physical capability to lift up to 50 lbs and safely handle heavy machine parts or loads
• Must be available to work 3rd shift (M-F, 11 pm-7 am) and train on 1st shift (7 am-3 pm) as required
• This is a direct-hire, on-site role - candidates must be local and capable of commuting
• Prior experience with tooling and project background preferred
