## About the Role

* Education/Training: Bachelor of Science in Engineering or Science. Master's degree preferred.
 * Experience: 5+ years of professional C++ software development experience, including substantial hands-on development and implementation of machine vision and image-processing algorithms. Experience with industrial automation, inspection equipment, or semiconductor manufacturing applications is preferred. Windows desktop development, C#/.NET, WPF, and integration with industrial imaging hardware are desirable but not required.
 * Skills/Technical Requirements (Required): Strong proficiency in C++ and object-oriented software design; demonstrated ability to implement, optimize, debug, and maintain production software. Practical development of computer vision/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 software development lifecycle. Effective communication and cross-functional collaboration.
 * Skills/Technical Requirements (Preferred): Windows desktop development, C#/.NET and WPF; industrial automation or semiconductor equipment software; industrial camera integration and image acquisition; 2D/3D imaging and camera calibration; factory diagnostics and production support; familiarity with lenses, optics, illumination, and lasers; TensorFlow or similar machine learning frameworks; UML and mentoring experience.

Job Conditions/Physical Demands :

Domestic or international travel may be required. Prolonged periods of sitting at a computer terminal. Use of a keyboard.

## Description

1. Design, develop, test, and maintain reliable, high-performance machine vision software using C++ for semiconductor manufacturing and automated inspection equipment.

 2. Develop, validate, and optimize practical computer vision and image-processing algorithms for object detection, segmentation, feature extraction, alignment, identification, measurement, and defect inspection.

 3. Design maintainable software components, interfaces, and architecture using object-oriented principles; independently own complex features and make sound technical design decisions.

 4. Integrate machine vision software with automated equipment and imaging systems; apply machine learning techniques when appropriate, rather than as a primary requirement.

 5. Participate in requirements analysis, design, implementation, code reviews, integration, testing, release, and performance improvement; collaborate with mechanical, electrical, software, and manufacturing teams.

 6. Troubleshoot difficult vision and software problems in development and production through analysis of logs, images, and system behavior; perform root-cause analysis and implement durable corrective actions.

 7. Support deployment and continuous improvement with manufacturing, field service, customers, and other stakeholders; provide technical guidance and mentoring as appropriate.

Supervisory Responsibility : May provide work leadership and training to lower-level professional employees but not required.
