Prototype Machinist

Job description

Job responsibilities

• Machine complex prototype and low-volume production components using CNC mills, lathes, and multi-axis machining centers.
• Interpret engineering drawings, CAD models, and GD&T requirements to determine optimal machining strategies.
• Set up, operate, and troubleshoot CNC equipment with minimal supervision.
• Collaborate directly with design and manufacturing engineers to improve part manufacturability and reduce iteration cycles.
• Program, edit, and optimize CNC programs and toolpaths to meet aggressive development timelines.
• Select tooling, workholding, and machining parameters appropriate for a wide range of materials and geometries.
• Perform first-article and in-process inspections using precision measurement equipment, including calipers, micrometers, height gauges, and CMMs.
• Identify root causes of machining and quality issues and implement corrective actions quickly.

Job requirements

• Strong proficiency reading engineering drawings, CAD models, and GD&T specifications.
• Experience setting up and operating 3-axis and 5-axis CNC machining centers.
• Ability to edit and troubleshoot G-code programs.
• Strong understanding of feeds, speeds, tooling selection, and machining fundamentals.
• Proficiency using precision inspection equipment and interpreting inspection results.
• Experience supporting aerospace, defense, robotics, space, automotive, or advanced hardware development programs.
• CAM programming experience using Fusion 360, Mastercam, NX CAM, HyperMill, or similar software.
• Experience machining aluminum, stainless steel, titanium, Inconel, and other difficult-to-machine materials.
