Sr. CNC Programmer

Job Summary  

The Senior CNC Programmer is a key technical expert within the manufacturing organization, responsible for developing highly efficient and reliable CNC programs that support complex plasticfabricated components. This role provides advanced programming leadership, drives continuous improvement in machining processes, and partners closely with engineering, production, and quality teams to ensure optimal throughput, precision, and repeatability. The ideal candidate brings deep CNC programming expertise, strong problemsolving ability, and a proactive approach to improving manufacturing operations. 

Responsibilities 

• Lead the development, writing, and optimization of CNC programs for multiaxis CNC routers, machining centers, and related equipment using advanced CAD/CAM software. 

• Interpret complex customer drawings, 3D models, and specifications—often created in SolidWorks—to define machining strategies that balance quality, cycle time, and manufacturability. 

• Establish machining standards, including tooling selection, workholding strategies, feeds/speeds, and process flow for both new product introductions and legacy parts. 

• Serve as the primary technical resource for CNC programming issues, troubleshooting program errors, machine behavior, and dimensional challenges. 

• Collaborate with Engineering teams to review SolidWorks models, clarify design intent, and provide designformanufacturability recommendations. 

• Drive continuous improvement initiatives that reduce cycle time, improve tool life, enhance machining quality, and increase machine utilization. 

• Create and maintain documentation, including setup sheets, tooling lists, 3D model references, and CNC programming standards. 

• Work closely with Supervisors and Machinists to validate programs on the shop floor and ensure safe, efficient, and accurate execution. 

• Participate in equipment and software evaluation to strengthen the organization’s machining capabilities. 

• Uphold all manufacturing SOPs, safety policies, and quality requirements while fostering a culture of precision and operational excellence. 

Qualifications 

• 5-7 years’ experience programming and setting up 3axis and 5axis CNC routers and machining centers. 

• Advanced proficiency in CAD/CAM programming using SigmaNest, Surfcam, and SolidWorks for model review, part interrogation, and toolpath planning. 

• Strong foundation in machining optimization, fixture design, tooling strategy, and process engineering. 

• Ability to interpret complex blueprints and 3D models, including GD&T and tighttolerance requirements. 

• Demonstrated success troubleshooting machining issues through rootcause analysis and corrective action. 

• Experience with CMM programming or operation is a strong plus. 

• Technical degree, trade school certification, or equivalent practical experience preferred. 

• Highly analytical with strong mechanical reasoning and a continuous improvement mindset. 

• Able to lead technical discussions, mentor machinists and other programmers, and collaborate crossfunctionally with engineering and production teams. 

• Effective communicator capable of conveying complex concepts clearly and professionally. 

• Independent, proactive, and accountable in decisionmaking and project execution. 

• Dedicated to safety, quality, accuracy, and operational excellence. 

• Bilingual (English/Spanish) preferred but not required.  

Physical Requirements 

• Ability to sit 6-8 hours  

• Adequate vision for reading blueprints, inspecting parts, and performing detailed machine setup tasks. 

• Ability to work in a manufacturing environment with exposure to noise, dust, mechanical motion, and fluctuating temperatures. 

• Ability to wear required PPE such as safety glasses, hearing protection, and protective footwear when required.
