Responsibilities

• Develop and document manufacturing processes for new and existing parts, including tool selection, cycle time optimization, and work-holding/fixture design.
• Program, set up, and troubleshoot Hydromat rotary transfer machines and CNC turning/milling equipment.
• Partner with Purchasing on tooling and material specifications, and with Quality Engineering on gauging, inspection methods, and process capability.
• Lead root cause analysis and corrective action for process-related scrap, downtime, and quality escapes.
• Design and specify fixtures, gauges, and work-holding to improve repeatability, throughput, and operator safety.
• Support first-article inspection, PPAP, and customer qualification activities for new or revised processes.
• Monitor process capability (Cpk/Ppk) using SPC data and drive continuous improvement initiatives.
• Maintain accurate routings, work instructions, and process documentation within the ERP/MES system.
• Support capital equipment evaluation, tooling investment justification, and automation projects.
• Ensure processes comply with applicable quality and regulatory requirements, including ISO 9001/AS9100 and, where applicable, ITAR and CMMC.
