Filament Winding Technician III

The role

This person will set up and operate multi-axis filament winding machines to wind composite overwrapped pressure vessels for Terran R. They will prepare resin and hardener mixes, develop wind programs, and perform in-process inspections.

What you will do

• Set up and operate multi-axis filament winding machines to wind composite overwrapped pressure vessels (COPVs) for Terran R
• Prepare resin and hardener mixes to specification and manage resin baths, fiber tensioning, and material handling for carbon, glass, and aramid fibers
• Help develop and refine wind programs and machine offsets based off engineering drawings and process specifications
• Perform in-process inspection and measurements (pi-tape, calipers, height gauge) and document results in work instructions and travelers
• Identify process bottlenecks and winding defects, and support troubleshooting and root-cause solutions with engineering
• Train and mentor less experienced technicians on winding, resin preparation, and cure processes

Required qualifications

• 7+ years of hands-on filament winding experience on composite pressure vessels or cylinders
• Experience setting up and operating multi-spindle filament winding machines (e.g., Entech, McClean Anderson), including axis offsets
• Working knowledge of carbon, glass, and aramid fiber systems and epoxy resin/hardener mixing
• Able to use and read precision measuring tools (pi-tape, calipers, height gauge, tension meters)
• Experience training or mentoring other technicians, with a strong commitment to safety and quality

Nice to have

• wet winding preferred
• Experience winding cylinders for aerospace, defense, DOT/compressed gas (CNG, hydrogen), or life-support applications
• Experience with vacuum bag, gel, and cure processes
• Lifting and rigging experience/forklift operation
• Able to read and interpret engineering drawings, blueprints, and specifications

Benefits

• competitive salary and equity
• generous PTO and sick leave policy
