• Conduct first article inspections (FAI) and support new product introductions (NPI).
• Identify, document, and report nonconforming products using NCR procedures.
• Support root cause investigations and corrective/preventive actions (CAPA).
• Perform visual inspections using microscopes and precision inspection equipment.
• Ensure manufacturing processes comply with ISO 9001, IPC standards, ESD requirements, and internal quality procedures.
• Maintain accurate inspection records and quality documentation.

AOI Programming

• Create, modify, validate, and optimize AOI inspection programs for new and existing products.
• Fine-tune inspection parameters to maximize defect detection while minimizing false calls.
• Support AOI machine setup, calibration, and routine maintenance activities.
• Analyze AOI inspection data and continuously improve program performance.
• Work closely with Process Engineering and Manufacturing Engineering to improve inspection effectiveness.
• Troubleshoot AOI equipment and programming issues.
• Validate AOI programs during new product introductions and engineering builds.
• Recommend process improvements based on AOI defect trends and inspection data.

Continuous Improvement

• Monitor production quality metrics and identify opportunities for improvement.
• Participate in Lean Manufacturing and continuous improvement initiatives.
• Support process capability studies and quality improvement projects.
• Assist with customer quality investigations and failure analysis.
• Collaborate with Production, Manufacturing Engineering, Process Engineering, Customer Success, and Supply Chain to resolve quality concerns.
• Promote a culture focused on quality, accountability, and continuous improvement.

Qualifications

• High school diploma or equivalent required; Associate degree or technical certification preferred.
• 2+ years of experience in electronics manufacturing, quality inspection, or AOI programming preferred.
• Experience with SMT and PCB assembly environments strongly preferred.
• Hands-on experience programming and operating AOI equipment (Mirtec, Koh Young, CyberOptics, Omron, Viscom, or similar systems) preferred.
• Working knowledge of IPC-A-610 and IPC J-STD-001 standards preferred.
• Familiarity with ISO 9001 quality systems.
• Ability to read engineering drawings, Gerber files, Bills of Materials (BOMs), and assembly documentation.
• Strong troubleshooting and analytical skills.
• Proficiency with Microsoft Office and manufacturing software systems.

Preferred Skills

• AOI Programming and Optimization
• SMT Process Knowledge
• PCB Assembly Inspection
• IPC-A-610 Inspection
• Quality Assurance (QA)
• Quality Control (QC)
• Root Cause Analysis
• CAPA
• First Article Inspection (FAI)
• Statistical Process Control (SPC)
• Lean Manufacturing
• Continuous Improvement
• ESD Compliance
• Manufacturing Documentation
• Cross-functional Collaboration

Physical Requirements

• Ability to stand and walk throughout the manufacturing facility for extended periods.
• Ability to lift up to 30 pounds occasionally.
• Manual dexterity for handling electronic assemblies and precision inspection equipment.
