## Description

We are seeking a talented and driven Machine Vision Software Engineer to design, develop, and deploy cutting-edge automated inspection and metrology systems for our advanced semiconductor manufacturing equipment. In this role, you will bridge the gap between hardware and software, leveraging C++ and MVTec HALCON to build high-performance, real-time vision algorithms that ensure sub-micron accuracy and high throughput., * Algorithm Development: Design, optimize, and implement robust machine vision algorithms using MVTec HALCON and C++ for semiconductor defect detection, alignment, metrology, and 2D/3D inspection.

 * Software Engineering: Write clean, maintainable, and high-performance C++ code in a multi-threaded, multi-process real-time Windows or Linux environment.
 * Hardware Integration: Interface software with industrial cameras (GigE), frame grabbers, optics, and specialized lighting systems.
 * System Calibration: Develop and calibrate high-precision coordinate transformation matrices (pixel-to-world) to ensure micron-level spatial accuracy.
 * Collaboration & Testing: Partner with mechanical, electrical, and automation engineers to test, debug, and validate vision systems on actual manufacturing tools.
 * Domestic and international travel is required for this position, up to 30%.
