JOB SUMMARY
Responsible for planning and programming machining sequence for precision machined components varying in size from 12" up to over 100". Work will consist of programming 3, 4 & 5 axis machining centers, horizontal and vertical lathes, and Okuma 5 axis VTL and HMC. Responsible for programming efficient tool paths and working with planning and shop personnel to analyze and improve cycle times on new and existing part programs used on various machine tools.

This position is subject to ITAR requirements which require incumbents to be a U.S. Person (Citizen, lawful permanent resident, a protected individual per 8 U.S.C. 1324(a)(3)).

PRIMARY DUTIES

Create CNC programs (G-code, macro style if applicable) for 3-axis, 4-axis and potentially multi-axis milling/turning of complex aerospace/defense parts.

Use CAD/CAM software (e.g., Mastercam, NX, Solid Works CAM, or similar) to generate toolpaths, select cutting tools, define machining strategy and verify the program prior to shop release.

Work with large/complex components (large castings/forgings, assemblies) and ensure program integrity, machine capacity, tooling, fixturing align with manufacturing needs.

Simulate and validate toolpaths (if simulation tools available) and make refinements to optimize cycle time, tool life and part quality.

Develop detailed setup sheets, tool lists, machining instructions and program release documentation for use by machinists and setup technicians.

Support first‑article runs: assist machinists/setup technicians during initial production of new jobs to validate program performance, identify issues, adjust as needed.

Recommend fixturing, work holding and tooling adjustments in collaboration with engineering and production as needed for stability and efficiency.

Review existing programs for improvement opportunities: reduce cycle time, improve tool life, reduce scrap, improve surface finish, enhance machine throughput.

Participate in continuous improvement initiatives (5S, lean manufacturing, standardization of programming practices) aligned with company manufacturing excellence goals.

Provide feedback to engineering regarding part manufacturability, tooling strategy, or machining feasibility early in job release or quoting phases.

Interface with the Engineering Manager, machinists, quality team, and production leadership to coordinate program launch, troubleshooting, and continuous support.

Communicate program changes, machining risks, tooling constraints or machine limitations promptly and effectively.

Participate when required in new product introduction (NPI), reviews of drawings/specifications, and help ensure programming considerations are accounted for.

Ensure all programs meet customer specifications, tolerances, drawing requirements including GD&T, finish, aerospace/defense industry standards.

Maintain program library, ensure revision control and proper documentation of changes.

Operate in compliance with internal quality systems (e.g., AS9100) and, where applicable, with customer/regulatory requirements for aerospace/defense parts.

Ensure compliance with aerospace/defense regulatory requirements (AS9100, ITAR, customer‑specific standards).
