Job Summary & Responsibilities

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.

Key Responsibilities

• 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%.

Qualifications

• Experience: Minimum 3+ years of hands-on experience in machine vision software development, specifically within the semiconductor or high-precision electronics manufacturing industry.

• Core Languages: Proficient in C++ with a strong understanding of object-oriented programming, data structures, and memory management.

• Vision Libraries: Extensive, production-level experience using MVTec HALCON (HDevEngine or HALCON/C++ integration).

• Domain Knowledge: Proven familiarity with semiconductor manufacturing processes (e.g., wafer inspection, die bonding, wire bonding, or packaging).

• Experience with software development methodologies such as Agile, Scrum, or Kanban.
