Senior Composite CNC Programmer/Machinist

Job description

Job responsibilities

• Program, set up, and operate large-format 5-axis CNC gantry routers and mills for trimming, drilling, and surfacing advanced composite components.
• Work closely with design and manufacturing engineers, providing real-time feedback on early-stage prototype models to optimize Design for Manufacturing (DFM).
• Design and fabricate robust work holding, including custom vacuum fixtures for delicate, near-net-shape parts.
• Machine master models and direct-to-part molds from foam, tooling board, and other pattern materials.
• Troubleshoot unique machining challenges inherent to composites, including delamination, fiber pull-out, and thermal degradation.
• Perform in-process quality control and dimensional verification to deliver high-quality prototype components with superior surface finishes.

Job requirements

• 4+ years of CAM programming experience (e.g., Esprit, hyperMILL) and 5+ years of hands-on CNC setup and operation.
• Deep understanding of machining complex composite and tooling materials, including carbon fiber (pre-preg and wet-layup), fiberglass, Kevlar, honeycomb, foam cores, and high-density urethane/epoxy tooling boards (e.g.,…
• Strong command of G and M code, high-speed 5-axis machining, GD&T, and experience with large-gantry 5-axis machines (CMS) and Fanuc controls.
• Expertise in cutting-tool selection for abrasive materials (e.g., PCD, diamond-coated routers, compression drills) and custom work holding.
• Proven ability to thrive in a fast-paced, rapidly changing R&D environment with a strong bias for action and minimal supervision.
• Passion for national security, defense technology, and solving critical hardware challenges.
• Must be a U.S. Person as this position requires access to export-controlled data.
• Advanced 5-axis simultaneous programming for complex surface contouring and trimming.
