About The Position

Cohu is seeking a Senior Vision Software Engineer to design, develop, and support advanced machine vision software for high-throughput semiconductor manufacturing equipment. The role focuses on high-performance C++ development and practical image-processing algorithms for device alignment, identification, inspection, metrology, and defect detection. The engineer will collaborate across disciplines to integrate vision software with automated equipment and support reliable production operation.

The position involves ownership of complex software features and technical design decisions, as well as participation throughout the software lifecycle—from requirements analysis and design through implementation, testing, release, and performance improvement. The engineer will troubleshoot vision and software problems in development and production and support deployment and continuous improvement with manufacturing, field service, customers, and other stakeholders. Applicants must be legally authorized to work in the U.S. without employer-sponsored visa sponsorship now or in the future.

Requirements

• Bachelor of Science in Engineering or Science.
• At least 5 years of professional C++ software development experience, including substantial hands-on development and implementation of machine vision and image-processing algorithms.
• Strong proficiency in C++ and object-oriented software design.
• Demonstrated ability to implement, optimize, debug, and maintain production software.
• Practical experience developing computer vision or image-processing algorithms using OpenCV or equivalent libraries, including techniques such as segmentation, feature extraction, object detection, pattern matching, alignment, or measurement.
• Experience with software testing, code reviews, Git-based source control, and the software development lifecycle.
• Effective communication and cross-functional collaboration skills.
• Legal authorization to work in the U.S. without employer-sponsored visa sponsorship, now or in the future.

Nice To Haves

• Master's degree.
• Experience with industrial automation, inspection equipment, or semiconductor manufacturing applications.
• Windows desktop development experience.
• Experience with C#/.NET and WPF.
• Experience integrating industrial cameras and image acquisition systems.
• Experience with 2D/3D imaging and camera calibration.
• Experience with factory diagnostics and production support.
• Familiarity with lenses, optics, illumination, and lasers.
• Experience with TensorFlow or similar machine-learning frameworks.
• UML familiarity.
• Mentoring experience.

Responsibilities

• Design, develop, test, and maintain reliable, high-performance C++ machine vision software for semiconductor manufacturing and automated inspection equipment.
• Develop, validate, and optimize computer vision and image-processing algorithms for object detection, segmentation, feature extraction, alignment, identification, measurement, and defect inspection.
• Design maintainable software components, interfaces, and architecture using object-oriented principles; independently own complex features and make sound technical design decisions.
• Integrate machine vision software with automated equipment and imaging systems, applying machine learning techniques when appropriate.
• Participate in requirements analysis, design, implementation, code reviews, integration, testing, release, and performance improvement.
• Collaborate with mechanical, electrical, software, and manufacturing teams.
• Troubleshoot vision and software problems in development and production by analyzing logs, images, and system behavior; perform root-cause analysis and implement durable corrective actions.
• Support deployment and continuous improvement with manufacturing, field service, customers, and other stakeholders.
• Provide technical guidance and mentoring as appropriate.
