Supports the team leader with the operations of the LOG (Large Optical Generator) and the LPM (Large Polishing Machine) to generate, fine grind, and polish large telescope mirrors ranging from 3m to 8.4m in diameter and weighing up to 18 tons. Performs duties with minimal supervision while following established procedures, and safety standards. Demonstrates knowledge of operating requirements and technical processes related to the optical fabrication of large-scale mirror production. Works with a team of technicians to take precise measurements, including optical, physical, and ultrasonic methods, to evaluate mirror conformance to scientists' and engineers' specifications including HREP, SCOTS, SLOTS, Test Plate, and Laser Tracker Measurements. Guides and trains lower-level staff. Supports the movement of mirrors throughout the lab using an air cart within inches of fixed obstacles. Works with team members on proper positioning of mirrors and follows the safety protocols required during the process. Enters data into the project logbooks and spreadsheets, including information on runs, measurements, machine parameters, and notes on run results. Filling out Daily reports. Knowledge, Skills, and Abilities (KSAs): Ability to lead a group of technicians in operating specialized equipment. Ability to work with minimal supervision. Ability to train and coach junior team members. Proficient with Microsoft Word and Microsoft Excel. Physical Requirements and Environmental Demands: Frequently lifts, moves, and transports equipment, tools, and materials associated with large-scale mirror fabrication processes (up to 50 lbs.) as required. Works in a manufacturing and laboratory environment where noise levels may require raised voices or hearing protection. Works in proximity to grinding, polishing, measurement, and transport equipment, as well as moving mechanical parts, electrical equipment, elevated work areas, and chemicals used in fabrication processes. May have skin or airborne exposure to oils, lubricants, cutting fluids, and other materials used in optical fabrication operations. Follow established safety protocols and personal protective equipment (PPE) requirements.
