• Lead day-to-day operation of Cambium’s 12  wide pilot prepreg line, including setup, threading, web tension, coating/nip gap, line speed, and temperature control
• Act as a lead for a small team of technicians, assigning daily tasks, providing hands‑on training, and serving as the first point of contact for line questions
• Oversee resin mixing and staging, including weighing, batching, viscosity checks, and pot-life management, to keep the line supplied and on schedule
• Ensure prepreg meets specification for resin content, areal weight, tack, and volatile content, and perform or coordinate in-process and final quality checks
• Plan and execute production runs to meet delivery schedules for internal development programs and external customers, and communicate status and risks to engineering
• Maintain accurate batch records, run logs, material traceability, roll labeling, and freezer inventory, including out‑time tracking
• Perform and schedule preventive maintenance on the prepreg line and mixing equipment, troubleshoot issues, and coordinate repairs to minimize downtime
• Provide feedback to improve standard operating procedures, work instructions, and training materials for prepreg and mixing operations
• Partner with engineers on new resin and fiber trials, process development, and scale‑up activities
• Follow all safety protocols, model safe behavior for the team, and contribute to our culture of safety
• Create and contribute to the product demonstration and engineering teams in a manner consistent with Cambium’s mission and values and the growth of Cambium’s business

KEY REQUIREMENTS

• High school diploma or equivalency certificate
• 5+ years of hands‑on experience operating hot‑melts or solvent prepreg, filming, or similar web‑handling/coating equipment
• Experience mixing and handling thermoset resin systems (e.g., epoxy, BMI, phenolic, cyanate ester)
• Demonstrated experience leading or training other technicians on the shop floor
• Working knowledge of prepreg quality checks such as resin content, areal weight, and tack
• Strong record keeping and attention to detail, including traceability and batch documentation
• Mechanical aptitude and…
