2d•$28 - $55•Onsite

About The Position

General Matter enriches uranium and is designing, building, and operating the world’s lowest-cost enrichment services in the US. The company aims to restore America’s ability to produce nuclear fuel to power AI, advanced manufacturing, and critical industries. General Matter is a mission-driven company with a culture of urgency, accountability, and transparency, seeking to make nuclear energy the cleanest, safest, and most affordable source of baseload power. They were incubated inside Founders Fund and are backed by top venture capital firms. The team is lean and world-class, applying a first-principles approach to nuclear fuel production. This role is critical to producing high-precision composite components.

Requirements

2+ years of hands-on experience in composite manufacturing, with direct experience in precision winding, fiber placement, or related cutting/layup processes
Working knowledge of carbon fiber material types (dry tow, prepreg, fabric) and proper handling/storage practices
Experience reading and interpreting engineering drawings, work instructions, and process travelers
Familiarity with precision measurement tools (calipers, micrometers, tension gauges)
Understanding of resin systems and cure cycle fundamentals (if wet winding/oven curing involved)
Ability to work with tight dimensional tolerances and maintain consistent process discipline
Strong attention to detail and documentation accuracy for traceability requirements
Physical effort including standing, lifting, and carrying equipment up to 50 lbs. unassisted.
Must be able to work all required shift hours, overtime and/or weekends as needed

Nice To Haves

Experience operating CNC-controlled composite equipment
Experience in regulated or high-reliability manufacturing environments (aerospace, defense, energy)
Experience with composite fabrication, pressure vessel winding, or structural composite components
Cross-trained in fabrication, bonding/adhesive application, or composite repair
Vocational/technical certification in composites manufacturing or materials science
Prior use of MES/QMS systems for production data entry and quality records

Responsibilities

Set up, operate, and monitor automated composite equipment (or equivalent composite fabrication equipment) to produce parts per engineering specifications and work instructions
Cut, measure, and prepare carbon fiber materials (tow, prepreg, fabric) using proper handling techniques to minimize waste and material degradation
Load and align mandrels, manage resin bath/wet-out systems, and verify winding patterns, tension settings, and ply schedules
Perform in-process inspections to confirm fiber placement, tension consistency, void content indicators, and dimensional conformance
Handle and store composite materials per shelf-life, temperature, and humidity control requirements (freezer logs, out-time tracking)
Operate curing equipment (ovens, autoclaves) and monitor cure cycles by process specifications, if applicable
Perform basic preventive maintenance and troubleshooting on composite equipment and ancillary machinery
Maintain accurate production records, traveler documentation, and material traceability logs
Identify and report process deviations, equipment malfunctions, or material defects to engineering/supervision
Follow all safety protocols related to composite dust, resin handling, PPE requirements, and machine operation
Support continuous improvement initiatives (5S, lean manufacturing, process optimization)
Collaborate with engineering and quality teams during process development
