CNC Programmer III

CNC Programmer III

The CNC Programmer III is a senior-level technical role responsible for advanced CNC programming, process development, and optimization of complex subtractive manufacturing operations. This position serves as a subject matter expert (SME) for multi-axis CNC machining, complex fixturing strategies, and advanced tooling applications. The role supports production, new product introduction (NPI), continuous improvement initiatives, and provides technical leadership to lower-level programmers and machinists.

The CNC Programmer III works cross-functionally with Engineering, Quality, Operations, and Supply Chain to ensure manufacturing processes meet cost, quality, and delivery objectives.

· Supports 3-axis and 4/5-axis CNC machining centers/Turning Centers

· Programs using CAM software (e.g., Camworks, Mastercam, Fusion 360, NX, etc.)

· Experience working with materials such as aluminum, steel, stainless, and specialty alloys

· Interfaces with:
Manufacturing Engineering, Quality (CMM inspection teams), Machine Operators / Setup Technicians

· Contributes to both prototype and production workflows

· Operates with moderate supervision; expected to independently manage standard programming tasks

· Develop, optimize, and validate CNC programs for complex machined components, including tight-tolerance and multi-setup parts.

· Program 3-, 4-, and 5-axis Simultaneous CNC milling and/or turning centers, including mill-turn and multi-spindle machines as applicable.

· Create and maintain CAM models, toolpaths, post-processors, and setup documentation.

· Select optimal cutting strategies, feeds/speeds, tooling, and work holding to maximize productivity and part quality.

· Troubleshoot and resolve machining issues related to tool wear, chatter, thermal effects, and dimensional variation.

· Lead machining process development for new product introductions (NPI) and engineering changes.

· Reduce cycle time, setup time, scrap, and rework through continuous improvement initiatives.

· Conduct root cause analysis (RCA) and implement corrective actions for machining-related issues.

· Support Lean Manufacturing, Six Sigma, and cost-reduction efforts.

Technical Leadership & Mentorship

· Provide technical guidance and mentorship to CNC Programmer I & II roles and machinists.

· Establish and maintain best practices, programming standards, and documentation.

· Support training initiatives for CAM software, machine controls, and advanced machining techniques.

· Serve as the primary technical escalation point for complex machining challenges.

· Collaborate with Design Engineering to ensure Design for Manufacturability (DFM).

· Work with Quality Engineering to ensure compliance with GD&T requirements, inspection plans, and control plans.

· Coordinate with Production, Maintenance, and Tooling teams to ensure equipment readiness and process stability.

· Support supplier machining capability assessments when needed.

· Create and maintain setup sheets, tooling lists, work instructions, and change documentation.

· Ensure compliance with internal quality systems, safety standards, and regulatory requirements.

· Support audits and continuous improvement reviews as required.

· Bachelor's degree in Manufacturing Engineering, Mechanical Engineering, or related field

OR

· Equivalent combination of education, technical training, and experience.
