The Quality Engineer supports and improves the Quality Management System (QMS) at our Milwaukee PCB fabrication facility, ensuring compliance with AS9100D, ISO 9001, customer specifications, and applicable regulatory requirements (ITAR) while driving continuous improvement across manufacturing, engineering, and purchasing.

This is a hands-on role with daily interaction on the production floor and regular collaboration with production, lab operations, CAM engineering, and management. You'll own real problems end to end — from root cause to verified corrective action.

Quality System & Compliance

• Maintain compliance with AS9100D, ISO 9001, and internal QMS procedures
• Support internal and external audits (customer, certification, regulatory)
• Assist with management review preparation and KPI reporting
• Maintain and update SOPs, work instructions, and control plans
• Ensure traceability and documentation integrity per ITAR/DFARS requirements

Corrective & Preventive Actions (CAPA)

• Lead root cause investigations (8D, 5 Whys, Fishbone, Pareto)
• Manage internal, supplier, and customer corrective actions and verify effectiveness
• Track nonconformance trends and drive systemic improvements

SPC & Process Control

• Implement and monitor SPC programs on critical processes (drill, plating, imaging, lamination, etch)
• Calculate and analyze Cp/Cpk for CTQ characteristics
• Support control plan development and partner with production to reduce variation and scrap

Manufacturing Support

• Provide daily floor support for quality-related issues
• Review first article inspections (FAIs) and customer-specific requirements
• Assist with cross-section analysis, plating thickness verification, and lab data review
• Disposition nonconforming material (MRB participation)

Supplier & Customer Quality

• Support supplier performance monitoring, scorecards, and incoming inspection trend review
• Participate in customer quality calls and audits
• Help Sales and Engineering interpret quality requirements for new programs

Continuous Improvement

• Drive Lean / Six Sigma initiatives
• Analyze scrap, yield, and rework data to identify cost-of-poor-quality reduction opportunities
• Improve documentation efficiency and digital quality records

Required

• Bachelor's degree in Engineering (Mechanical, Chemical, Industrial, Electrical, or related field)
• 2–5 years of experience in manufacturing quality (PCB fabrication preferred)
• Experience with SPC, Cp/Cpk, and statistical analysis
• Experience using AI tools
• Strong root cause analysis and problem-solving skills
• Proficiency in Excel and data analysis
• Ability to work on-site in Milwaukee, WI

Preferred

• Experience in PCB fabrication or electronics manufacturing
• Familiarity and/or certifications with IPC standards (IPC-A-600, IPC-6012)
• Working knowledge of AS9100 or ISO 9001
• Knowledge of plating chemistry or wet process controls
• Six Sigma certification (Green Belt or higher)
• Internal auditor training or audit experience

• Family-owned with 35+ years in the industry, we offer the stability of an established manufacturer with the pace and visibility of a growing operation. You'll work directly with leadership, see your improvements take effect on the floor, and build expertise in one of the most technically demanding segments of electronics manufacturing — aerospace and defense PCB fabrication.
