• CAD proficiency (SolidWorks or similar) and ERP/MES familiarity.
• Strong shop-floor troubleshooting ability.
• Experience with materials common to precision components (carbide, UHMW, stainless).
• Experience in defense/aerospace environments (ITAR, AS9100, CMMC) is a plus.

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 to support production runs and new part introduction.
• 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 quality and regulatory requirements, including ISO 9001/AS9100 and ITAR/CMMC where applicable.
