Responsibilities

Create, validate, and maintain CNC programs that support the machining of large-scale, complex, precision metal components fabricated on plasma and oxy-fuel cutters (CAM file generation, post-processor machine code generation).
Perform technical data package review of components that require fabrication (CAD models & engineering drawings).
Develop advanced nesting strategies to maximize material utilization and minimize scrap.
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, ‘tabletop’ peer reviews, First Time Process Reviews, machine dry runs).
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.
Evaluate new equipment, software upgrades, and cutting technologies; make recommendations for capital investments.
