About The Position

We are seeking a CNC Shop Manager who is both a strong people and operations leader and a hands-on CNC programmer. This is a player-coach role responsible for the daily performance of a six-machine aerospace machining environment, including staffing, scheduling, cost control, policy and procedure development, and direct CAM programming support. The ideal candidate is equally comfortable building shop structure and jumping into Mastercam/other CAM software to program complex parts, prove out jobs, and standardize setups.

Requirements

7+ years CNC machining experience with advanced 5-axis programming.
Expert-level Mastercam proficiency (toolpaths, posts, simulation, multi-axis strategies).
2–3+ years leading machinists or shop personnel.
Strong GD&T, blueprint reading, and tight-tolerance aerospace experience.
Experience building SOPs, setup documentation, and process standards.
Familiarity with ERP/MRP systems and production tracking.
Ability to balance floor presence with administrative and leadership duties.

Nice To Haves

Aerospace or high-mix/low-volume manufacturing background.
Lean / Continuous Improvement training or certifications.
AS9100 or ISO-compliant environment experience.
Experience standing up new shops, cells, or process overhauls.
Proven tooling and vendor cost-reduction wins.

Responsibilities

Oversee daily CNC shop operations to meet on-time delivery, quality, and cost targets.
Manage headcount planning, shift schedules, timecards, and performance management.
Establish and enforce shop policies, SOPs, safety standards, and documentation practices.
Drive accountability, training, and continuous improvement culture.
Coordinate priorities with Engineering, Quality, and Supply Chain.
Create, modify, and optimize 3-axis and 5-axis CNC programs in Mastercam.
Support complex setups, prove-outs, and first-article inspections.
Develop and maintain setup sheets, tooling libraries, post processors, and revision control.
Improve cycle times, feeds/speeds, and tool paths to reduce scrap and increase throughput.
Troubleshoot machining, tooling, and fixturing issues on the floor.
Monitor KPIs: spindle utilization, scrap rate, labor efficiency, and on-time delivery.
Manage tooling vendors, consumables, and cost-reduction initiatives.
Build repeatable processes and standardized work instructions.
