The CAD/CAM Programmer | CNC Machinist is a senior-level, dual-competency role that combines hands-on machining expertise with advanced programming capability and a strong focus on team development and process efficiency. This position is responsible for writing, proving out, and optimizing CNC programs, supporting complex machine setups, troubleshooting programs and processes on the floor, and actively training and coaching the machinist team. 

This role serves as a key technical resource for the machine shop bridging the gap between engineering intent and shop floor execution. The ideal candidate is a highly experienced machinist who has developed strong programming skills and takes genuine satisfaction in making others better. They are equally comfortable writing programs at a computer, running a complex setup on the floor, and standing alongside a machinist to teach them how it is done. 

CNC Programming & Optimization 

• Write, edit, and optimize CNC programs using CAM software (Mastercam, Fusion 360, SolidWorks CAM, or equivalent) for milling, turning, and multi-axis machining operations 

• Prove out new programs on the machine verifying tool paths, confirming dimensional accuracy, and releasing programs to production 

• Edit and optimize G-code at the control to improve cycle time, extend tool life, and reduce scrap 

• Maintain an organized library of proven programs, tooling setups, and machining templates for repeat jobs 

• Select cutting tools, speeds, feeds, and machining strategies appropriate for each job and material type 

• Troubleshoot program errors, toolpath issues, and dimensional non-conformances to identify root causes and implement corrections 

Complex Setup Support & Floor Presence 

• Provide setup support to machinists on complex, first-time, or high-risk jobs and walk through the setup process, verify fixtures and offsets, and ensure the job is running correctly before stepping away 

• Lead setup for prototype, first-article, and one-off parts where standard procedures do not yet exist 

• Serve as the go-to resource on the floor when machinists encounter problems they cannot resolve independently 

• Perform and support first-article inspection to verify that programs and setups are producing parts to specification 

• Troubleshoot machining issues on the floor including tooling failures, dimensional non-conformances, surface finish concerns, and material-related challenges 

 Machinist Training & Development 

• Actively train machinist to walk through setups, explain program logic, demonstrate techniques, and verify understanding before leaving a machinist to run independently 

• Develop setup sheets, work instructions, and visual aids that machinists can reference independently on repeat jobs 

• Support the onboarding of new machinists by providing structured, hands-on guidance during the early stages of their ramp-up 

• Identify skill gaps on the team and work with the Machine Shop Manager to develop targeted training plans 

• Model the highest standard of craftsmanship, safety, and shop discipline at all times 

Process Efficiency & Continuous Improvement 

• Identify opportunities to reduce cycle time, eliminate waste, and improve consistency across existing machining programs and processes 

• Reprogramming or restructuring inefficient jobs documenting the before and after results and communicating improvements to the team 

• Collaborate with Engineering on design-for-manufacturability (DFM) feedback, new part introductions, and iterative builds 

• Support fixture and work-holding improvements that simplify setups and reduce setup time for the machinist team 

• Document processes, parameters, and revision histories to support repeatability and knowledge transfer 

• Contribute to scrap reduction efforts by identifying the programming or setup root causes of recurring quality escapes 

Required 

• High school diploma, GED, or equivalent required 

• 8+ years of progressive CNC machining experience including complex multi-axis setup 

• Demonstrated CAM programming experience using Mastercam, Fusion 360, SolidWorks CAM, or equivalent 

• High proficiency in G-code with the ability to read, write, edit, and optimize programs at the control 

• Demonstrated ability to train machinists 

• Experience with tight-tolerance machining and precision measurement tools including CMM 

• Ability to read and interpret complex engineering drawings and GD&T 

Preferred 

• Trade certificate, technical degree, or apprenticeship in machining, manufacturing, or a related field 

• Experience using SolidWorks or Autodesk Inventor for part and assembly review 

• Background in prototype machining, R&D, or new product introduction environments 

• Experience machining titanium, stainless steel, carbon fiber, composites, or other advanced materials 
• Background in a lead or training role within a machine shop environment 
• Familiarity with orthotic and prosthetic device manufacturing or medical device environments 

Technical Skills 

• Advanced CNC machining: multi-axis milling, turning, drilling, and grinding 

• CAM software proficiency: Mastercam, Fusion 360, SolidWorks CAM, or equivalent 

• Expert G-code knowledge: ability to write, edit, and optimize programs at the control 

• Precision measurement: CMM, optical comparator, micrometers, calipers, and gauges 

• Tooling expertise: cutting tool selection, tool life optimization, speeds and feeds for varied materials 

• Fixture and work-holding design for non-standard, prototype, and low-volume parts 

• Advanced GD&T interpretation and application 

• CAD software familiarity: SolidWorks or Autodesk Inventor for model and drawing review 

Training & Communication Skills 

• Demonstrated ability to explain complex technical concepts clearly to machinists at varying skill levels 

• Patient, thorough, and genuinely invested in the development of others 

• Able to develop written work instructions, setup sheets, and training materials that machinists can use independently
