The AOI Engineer is responsible for developing, optimising, maintaining, and improving Automated Optical Inspection (AOI) systems used in manufacturing processes. This role ensures effective defect detection, minimises false calls, improves inspection accuracy, and supports continuous quality improvement initiatives. The engineer collaborates closely with Process, Quality, Manufacturing, Equipment, and Product Engineering teams to achieve yield, quality, and productivity targets.
ESSENTIAL DUTIES AND RESPONSIBILITIES:
- Develop, optimise, and maintain AOI inspection programs for new and existing products.
- Create and validate AOI recipes, defect libraries, and inspection standards.
- Fine-tune vision algorithms, lighting, and camera settings to maximise defect detection and minimise false calls.
- Support New Product Introduction (NPI) activities and ensure AOI readiness for production ramp-up.
- Troubleshoot AOI-related production, yield, and quality issues.
- Perform root cause analysis and implement corrective and preventive actions (CAPA).
- Analyse defect trends and drive yield, quality, and process improvement initiatives.
- Support preventive maintenance, calibration, and equipment upgrades.
- Develop automated defect classification (ADC) and smart inspection solutions.
- Evaluate and implement AI, Machine Learning, and advanced vision technologies.
- Integrate AOI systems with MES, SPC, and Industry 4.0 manufacturing platforms.
- Generate and analyse AOI performance reports, dashboards, and KPIs.
- Collaborate with Process, Quality, Product, Manufacturing, and Equipment Engineering teams.
- Develop and maintain SOPs, OCAPs, inspection criteria, and engineering specifications.
- Drive continuous improvement, cost reduction, and automation projects.
- Provide technical training, mentorship, and knowledge sharing on AOI systems.
- Work with equipment vendors on machine optimisation, troubleshooting, and new capability development.
- Lead innovation projects to enhance inspection accuracy, efficiency, and manufacturing performance.
- Ensure compliance with quality, safety, and customer requirements.
Required:
- Bachelor's Degree in Electrical Engineering, Electronic Engineering, Mechatronics Engineering, Mechanical Engineering, Manufacturing Engineering, Computer Engineering, or related Engineering disciplines.
