Job description:

Play a critical role in CNC programming, process planning, tooling, machine tool selection, and continuous improvement for multi-axis CNC machining operations. Define and optimize machining strategies-including tooling, fixturing, machine selection, and coolant or lubrication delivery-driving efficient, high-quality, and cost-effective production of precision plastic transparencies. Reporting to Senior Manager of Plant Operations Engineering.

Responsibilities:

• Develop, modify, and optimize CNC programs for multi-axis (3, 4, 5-axis) milling machines to support manufacturing of plastic transparencies, composites, and aerospace tooling components.
• Utilize CAM software such as Mastercam, NX, CATIA, or similar.
• Design and qualify cutting tools, fixturing, and work holding for aerospace and precision plastic CNC machining applications.
• Establish and continuously refine machining parameters, coolant/lubrication delivery, and machining strategies to drive stable, repeatable production while meeting requirements for tool life, dimensional accuracy, surface finish, and AS9100 compliance.
• Apply CNC simulation and verification tools (e.g., VERICUT) for digital twin validation, collision avoidance, and process reliability.
• Interpret and create technical drawings, GD&T, and 3D CAD models to produce accurate and compliant toolpaths.
• Evaluate and implement emerging machining technologies, tooling solutions, and industry best practices by actively researching suppliers, attending trade shows, and benchmarking new techniques.
• Evaluate, qualify, and recommend new CNC machinery and equipment, supporting strategic capital investment decisions to enhance precision plastic manufacturing capability, process reliability, and compliance with AS9100 and industry standards.

Education and Experience:

Bachelor's Degree in Manufacturing or Mechanical Engineering preferred

7+ years of progressive experience in CNC programming and machining in aerospace, defense, and high-precision industries, with experience in plastics machining

Proficient in 3-, 4-, and 5-axis CNC machining, with experience on Zimmermann, CMS, Makino, DMG MORI, Mazak, Okuma, or Haas platforms

Skilled in Siemens SINUMERIK, Fanuc, and Mazatrol controls

Experienced in CAD/CAM software (Siemens NX, CATIA, Mastercam) and G-/M-code programming

Skills and knowledge:

• Able to follow instructions, sketches, blueprints, engineering drawings and manuals
• Capable of problem-solving: Exercises judgment, based on previous experience, practices and precedents, to identify and solve problems that arise with little or no precedent
• Effective oral and written communication
• Knowledge of GD&T (ASME Y14.5) and blueprint interpretation, applied to aerospace and high-precision manufacturing tolerances.
• Only U.S. Citizens, Green Card holders, and political asylees or refugees are eligible to apply.
