Job summary

Greystone, Inc. is seeking a Process Engineer to develop, optimize, and troubleshoot manufacturing processes for precision-machined components, focusing on Hydromat rotary transfer and CNC equipment.

You will own the path from part print to repeatable production, coordinating with Purchasing, Quality Engineering, and the shop floor to maintain capable, on-cost processes. The role requires hands-on CNC programming and fixture design, with knowledge of GD&T, SPC, Lean Six Sigma, and ERP/MES

Qualifications

• Bachelor's degree or equivalent hands-on experience in process engineering.
• 3+ years of process engineering in precision machining/high-volume manufacturing.
• Hands-on CNC programming/setup; Hydromat or similar experience preferred.
• Knowledge of GD&T, blueprint reading, and dimensional inspection equipment.
• Familiarity with SPC and Lean/Six Sigma methods.
• 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.

Job description

Position Summary

The Process Engineer is responsible for developing, optimizing, and troubleshooting the manufacturing processes that run our precision-machined components, with a focus on Hydromat rotary transfer and CNC equipment. This role owns the technical path from part print to repeatable production — tooling, fixturing, cycle time, and process documentation — and partners closely with Purchasing, Quality Engineering, and the shop floor to keep processes capable, on cost, and on schedule.

Key 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 applicable quality and regulatory requirements, including ISO 9001/AS9100 and, where applicable, ITAR and CMMC.

Required Qualifications

• Bachelor's degree in Mechanical, Manufacturing, or Industrial Engineering, or equivalent hands‑on process engineering experience.

• 3+ years of process engineering experience in a precision machining or high-volume manufacturing environment.

• Hands‑on CNC programming/setup experience; rotary transfer machine experience (Hydromat or similar) strongly preferred.

• Working knowledge of GD&T, blueprint reading, and dimensional inspection equipment (CMM, optical comparators, hand gauges).

• Familiarity with SPC and structured problem‑solving methods (8D, fishbone, 5‑why) and continuous improvement (Lean/Six Sigma).

• Proficiency with CAD software (SolidWorks or similar) and ERP/MES systems.

• Strong hands‑on troubleshooting ability and comfort working directly on the shop floor.

Preferred Qualifications

• Experience in a defense or aerospace manufacturing environment (ITAR, AS9100, CMMC).

• Lean/Six Sigma Green Belt or Black Belt certification.

• Experience machining specialty materials (carbide, UHMW, stainless, or similar).

Work Environment & Physical Requirements

• Primarily a plant‑floor environment with exposure to machining coolant, noise, and moving equipment; safety glasses and required PPE must be worn.

• Ability to stand or walk for extended periods and occasionally lift up to 35 lbs.

• Occasional travel may be required for supplier or customer visits.
