Vision Engineer Team Lead building Apple-certified AOI and AI defect detection systems.
IndiaWhat I'm looking for
I’m a Vision Engineer Team Lead focused on delivering Apple-certified AOI and measurement systems for iPhone housing inspection. I’ve led deep learning model development for cosmetic defect detection, combining hybrid rule-based and AI approaches on UMPT2 platforms to drive reliable, high-precision results.
In my recent roles, I architected and deployed a YOLOv8-based defect detection pipeline and improved production outcomes through fine-tuning, threshold calibration, and multi-class confidence optimization. I also build end-to-end inspection readiness by managing datasets (50,000+ images), maintaining versioned model registries, optimizing camera/lighting setups, and reviewing escape/overkill KPIs with quality teams.
