We are seeking an Onsite CNC Machinist to join our Extreme Precision Optics team in Richmond, CA. As a CNC Machinist, you will work with CNC milling equipment to manufacture high precision glass components. Key Responsibilities Independently plan, set up, program support, and execute complex jobs requiring advanced precision and attention to detail. Collaborate closely with engineering, quality, and planning to meet on-time delivery schedules, resolve technical issues, develop processes, tooling, and testing methods for new products; document standard work and mentor/train machinists on new methods. Lead continuous improvement efforts to enhance safety, quality, throughput, and repeatability, and provide technical guidance to less experienced machinists. Operate CNC and non-CNC machines to produce complex, high-precision components from glass and ceramic materials to demanding tolerance and surface requirements. Lead complex work holding and machining strategies for low-volume, high-precision parts, independently set up and operate 3, 4 & 5-axis CNC vertical milling centers; select tooling, offsets, and fixturing to achieve required tolerances. Load, edit, and manage CNC programs; support program prove-out, revision control, and safe implementation of engineering changes. Troubleshoot machining issues and implement corrective actions. Handle and clean optical components using established contamination-control practices; coach others on safe handling requirements. Own and enforce a clean and orderly work environment by following cleaning schedules, 5S practices, and inventory control. Perform maintenance and preventative maintenance on equipment and tooling; identify root causes and partner with maintenance/engineering to prevent recurrence.
