  • Create and edit CNC programs that support the machining of large-scale, complex, precision metal components fabricated on multiple-axis CNC milling & turning machining centers (CAM file generation, post-processor machine code generation)

  • Perform technical data package review of components that require fabrication (CAD model & engineering drawing validation)

  • Perform machining process development & optimization (part setup/fixturing, machining strategy/order of operations, tool selection, speed/feed process parameter selection)

  • Identify, select, and procure appropriate tooling for job specific applications (based on part material, geometry, features, tolerances, system rigidity, and equipment capability )

  • Perform program prove-out validation (computer simulation tools, ‘table top’ peer reviews, First Time Process Reviews, machine dry runs)

  • Work with machinists, manufacturing engineers, and design engineers to identify process improvement opportunities (reduced machining/setup time, improved part quality, reduced manufacturing risk) and incorporate required design changes (customer driven changes, technical performance improvements, improved manufacturability)

  • Participate in and lead cross-functional teams comprised of machinists/operators, manufacturing engineers, production supervisors, supply chain representatives, quality engineers/inspectors, and operations/program management to support program schedule & performance goals, mitigate manufacturing risks, and improve operational efficiency


  • This job requisition is for a 1stShift position; however, occasional extended shift, off-shift, and/or weekend support may be required

  • Occasional travel may be required for training purposes or to participate in equipment selection/acceptance activities (less than 10%)

Basic Qualifications:

  • Bachelors degree in an STEM discipline (Science, Technology, Engineering or Math) and 5 years of relevant work experience

  • 2 years direct experience working in a machining CNC programming role

  • Ability to read, interpret, and understand engineering technical data packages (CAD models, engineering drawings, quality inspection/control plans, manufacturing instructions) including Geometric Dimensioning and Tolerancing (GD&T)

  • Ability to create and edit CNC programs that support the machining of large-scale, complex, precision metal components

  • Demonstrated proficiency/experience using Microsoft Office (Word, Excel, and PowerPoint)

  • Candidate must be detail oriented, highly organized, and possess excellent written & verbal communication skills

  • Experience creating and/or editing 3D CAD models
