• Strong understanding of convolutional neural networks (CNNs), object detection, and classification techniques

• Experience with image datasets, preprocessing techniques, and feature extraction

• Familiarity with hardware acceleration for AI inference (e.g., TensorRT, ONNX, CUDA, Edge TPU)

• Experience deploying machine learning models in real-world environments (cloud, edge computing, or embedded systems)

• Ability to process large datasets and optimize model performance for real-time applications

• Experience with X-ray or hyperspectral imaging is a plus

• Familiarity with industrial automation, robotics, or manufacturing environments is a plus

Physical Requirements:  

• Ability to perform the essential job functions consistent safely and successfully with the ADA, FMLA and other federal, state and local standards, including meeting qualitative and/or quantitative productivity standards

• Ability to maintain regular, punctual attendance consistent with the ADA, FMLA and other federal, state, and local standards 

Working Conditions:  

• Environment, such as office or outdoors

• Ability to work in challenging working conditions which may include exposure to noise, dust, chemicals, and temperature extremes, while protected by PPE, for extended periods of time

• Essential physical requirements, such as climbing, standing, stooping, or typing

• Occasional work weekends, nights, or be on-call as a regular part of the job

• Occasional travel requirements
