CNC Programmer

Job Functions

• Read, interpret, and build to blueprints, 3D CAD models, and engineering drawings.
• Perform precision wet layup and vacuum bagging of carbon fiber and fiberglass components.
• Prepare, clean, and treat molds utilizing appropriate release agents, waxes, and semi-permanent coatings.
• Select, mix, and apply appropriate resin systems (epoxy, polyester, vinyl ester) based on engineering specifications, ensuring proper resin-to-fiber ratios.
• Expertly apply vacuum bagging consumables, including peel ply, breather, bleeder, and sealant tape to ensure high-quality part consolidation.
• Utilize handheld power and pneumatic tools for trimming, sanding, and finishing composite parts (grinders, sanders, Dremels, etc.).
• Perform secondary bonding of composite-to-composite and composite-to-metal structures using structural adhesives.
• Operate shop equipment such as waterjets, bandsaws, and table saws for material preparation and template creation.
• Execute assigned fabrication tasks independently, meeting quality standards and deadlines, while adhering to established safety processes (PPE, vapor mitigation, and dust control).

Required Qualifications

• 5+ years of experience in composite fabrication (Carbon Fiber and Fiberglass).
• Deep understanding of vacuum bagging processes, including bag plumbing and troubleshooting vacuum leaks.
• Demonstrated knowledge of composite materials, including various weaves (plain, twill, satin) and core materials (honeycomb, foam).
• Proficiency in resin chemistry, including accurate mix ratios, catalyst percentages, pot-life management, and ambient temperature curing requirements.
• Proficient layout and measurement skills utilizing calipers, tape measures, and fixturing tools.
• High attention to detail and organization, particularly regarding clean-room standards and resin shelf-life tracking.
• Physical job requirements:
• Ability to lift 50+ lbs consistently.
• Stand for long periods of time, bend or twist body, kneel, stoop, or crouch.

Additional Skills

• Experience with complex mold geometries and multi-part tooling.
• General knowledge of 2D and 3D CAD software.
• Experience operating CNC equipment (e.g., waterjet, laser cutter) for precision ply cutting.
• Basic proficiency in MIG/TIG welding and metal fabrication to assist in multi-material prototype assemblies.
