Job description
CNC Programmer IIIThe 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.Key Responsibilities· 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 tasksSkills, Knowledge and Expertise· 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.Process Development & Optimization· 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.Cross-Functional Collaboration· 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.Documentation & Compliance· 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.Required QualificationsEducation· Bachelor's degree in Manufacturing Engineering, Mechanical Engineering, or related fieldOR· Equivalent combination of education, technical training, and experience.Experience7–10+ years of CNC programming experience in a subtractive manufacturing environment.Demonstrated expertise programming complex parts using CAM software (e.g., Camworks, Mastercam, NX, PowerMill, ESPRIT, GibbsCAM, or similar).Strong experience with: o Multi-axis machining o Tight tolerances (±0.0005" or tighter where applicable) o Complex GD&T interpretationPrevious experience supporting production and NPI environments.Technical Skills· Advanced proficiency with CNC controls (e.g., Fanuc, Siemens, Haas, Mazatrol, Heidenhain).In-depth knowledge of: o Cutting tool geometry and coatings o Workholding and fixturing o Material behavior (steel, aluminum, titanium, superalloys, etc.)Strong understanding of metrology and inspection methods.Ability to read and interpret engineering drawings and models (2D/3D).Soft Skills & Competencies· Strong analytical and problem-solving skills.Ability to work independently with minimal supervision.Effective communication skills for technical and non-technical audiences.Proven ability to lead by influence rather than authority.High attention to detail and safety awareness.Preferred Qualifications· Experience with aerospace, medical, automotive, defense, or high-precision manufacturing.Familiarity with PLM/MES systems.Lean Manufacturing or Six Sigma certification.Hands-on machining experience (setup and prove-out).Physical & Work Environment· Ability to spend time on the manufacturing floor.Occasional lifting of tooling or fixtures within safety guidelines.Exposure to typical machine shop conditions.Working Conditions· Combination of office (CAM programming) and shop floor environment· Exposure to machining noise, coolant, and metal chips· May require extended periods standing on the production floorAll Employees Shall:· Comply with the EH&S Policy and applicable regulatory and company EH&S rules and requirements· Report to supervision conditions or practices that are either unsafe or that may adversely impact the environment, to ensure prompt resolution of potential hazards· Attend scheduled EH&S training program· Actively support the organization's efforts to meet or exceed EH&S goals and plans· Recommend improved EH&S practices Must be able to communicate effectively with co-workers, supervisors, and third parties. This ability to communicate requires the employee to be conversant in English as the majority of our workforce and the third parties that we encounter only speak English.
