About the role

Onto Innovation is a leader in process control, combining global scale with an expanded portfolio of leading-edge technologies that include: 3D metrology spanning the chip from nanometer-scale transistors to micron-level die-interconnects; macro defect inspection of wafers and packages; metal interconnect composition; factory analytics; and lithography for advanced semiconductor packaging. Our breadth of offerings across the entire semiconductor value chain helps our customers solve their most difficult yield, device performance, quality, and reliability issues. Onto Innovation strives to optimize customers’ critical path of progress by making them smarter, faster and more efficient.

Responsibilities

• Design, optimize, and implement robust machine vision algorithms using MVTec HALCON and C++ for semiconductor defect detection, alignment, metrology, and 2D/3D inspection.
• Write clean, maintainable, and high-performance C++ code in a multi-threaded, multi-process real-time Windows or Linux environment.
• Interface software with industrial cameras (GigE), frame grabbers, optics, and specialized lighting systems.
• Develop and calibrate high-precision coordinate transformation matrices (pixel-to-world) to ensure micron-level spatial accuracy.
• Partner with mechanical, electrical, and automation engineers to test, debug, and validate vision systems on actual manufacturing tools.
• Domestic and international travel required for this position, up to 30%.

Requirements

• Minimum 3+ years of hands-on experience in machine vision software development, specifically within the semiconductor or high-precision electronics manufacturing industry.
• Proficient in C++ with a strong understanding of object-oriented programming, data structures, and memory management.
• Extensive, production-level experience using MVTec HALCON (HDevEngine or HALCON/C++ integration).
• 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.
• Strong background in digital image processing, matrix mathematics, 2D/3D geometry, and camera calibration.
• Bachelor’s degree in Computer Science, Electrical Engineering, Mechatronics, or a related technical field.

Skills

• Experience with additional vision/GUI libraries like OpenCV (nice to have).
• Familiarity with SECS/GEM communication protocols (nice to have).
• Knowledge of deep learning extensions within HALCON for anomaly detection (nice to have).

Benefits

• Competitive salaries and comprehensive benefits package.
• Health, dental, and vision coverage.
• Life and disability insurance.
• Paid time off (PTO).
• 401(k) with employer match.
• Employee Stock Purchase Program (ESPP).
• Wellness initiatives.
• Access to cutting‑edge tools.
• Collaborative, inclusive culture.
