CNC Machinist/Programmer

Role SummaryThe CNC Machinist / Programmer is responsible for creating, managing, and optimizing CNC programs using Mastercam for 3 to 5-axis milling machines. This role requires a strong programming background to analyze engineering data, develop tooling strategies, and produce setup documentation that supports the broader production team. The CNC Machinist / Programmer sets up and operates milling machines to machine aluminum and trim composite parts, interprets blueprints and engineering specifications, and monitors quality to ensure all work meets customer tolerances and company standards. Candidates with additional experience programming and operating a gantry-style CMM for dimensional inspection are strongly preferred, as this is a desired secondary capability for the role.Duties & ResponsibilitiesCreate, modify, and store original CNC programs using Mastercam for 3, 4, and 5-axis milling machinesAnalyze drawings and design data to determine appropriate tooling, work holding, machine speeds, and feed ratesProduce setup documentation, tooling documentation, and shop-aided drafting prints to support operators and machinistsVerify and simulate CNC programs against CAD models to ensure accuracy prior to runningTroubleshoot and resolve program and process issues, coordinating with other functional areas as neededPlan, design, and produce work holding and job-specific fixtures as requiredAssist operators and machinists with program processes and provide in-process production supportEnsure parts and tools are loaded correctly and quality is consistently maintained throughout each assignmentChange and adjust cutters as required to meet quality and tolerance requirements; ensure machinery and tools are properly maintainedEnsure accurate documentation is entered on Manufacturing Orders, including correct quantities and specification recordingFocus on continuous improvement through increased throughput and reduced changeover timeStay current with new versions of Mastercam and related programming softwareWhen required, program and operate the company's gantry CMM to perform dimensional inspections and generate inspection reportsPerform other duties as assignedSkills & KnowledgeExpert proficiency in Mastercam CAM software for 3, 4, and 5-axis programmingStrong working knowledge of G-code and CNC machine setup, monitoring, and change-out proceduresAbility to analyze engineering drawings, blueprints, and design data to develop effective machining strategiesExperience creating setup and tooling documentation to support shop floor operationsProficiency with machine probing for in-process part measurementAbility to apply mathematical functions related to machining, tooling design, and dimensional computationExperience in both production and prototyping environmentsStrong mechanical aptitude and meticulous attention to detailCMM programming and operation experience preferred, ideally with gantry-style or large-format equipmentFamiliarity with GD&T and its application to dimensional inspection is a plusProficient in Microsoft Office (Excel, Word, PowerPoint)Effective written and verbal communication skills, with the ability to collaborate across functional teamsMinimum QualificationsAssociate degree in Machining Technology or equivalent relevant work experience (2–3 years)3–5 years of expert-level Mastercam experience with 3, 4, and 5-axis programming requiredExcellent knowledge of G-code requiredCMM programming and operation experience preferred but not requiredAbility to lift and/or move up to 25 lbs frequentlyAbility to stand for extended periods and work in environments requiring ear and respiratory protectionSelf-motivated, self-managed, and capable of working independently or as part of a collaborative teamTeam player who actively contributes to continuous improvement initiatives
