• Extract, clean, transform, label, annotate, and interpret image, biometric, transactional, and related datasets within a defined problem space to support model development and analytical reporting.
• Apply computer vision, statistical, and machine-learning techniques to design, train, evaluate, fine-tune, and deploy models that inform mission decisions.
• Apply image-analysis techniques such as image classification, object detection, image segmentation, image matching, feature extraction, face detection, facial verification, image-quality analysis, or related computer-vision capabilities.
• Explore and compare a variety of modeling tools, methods, and programming languages to identify high-performing analytical and image-analysis approaches.
• Support exploratory data analysis, feature development, image-data preparation, annotation, training-set construction, model evaluation, and model-improvement activities.
• Assess model performance, including false positives, false negatives, model bias, data-quality issues, and operational limitations; recommend improvements as needed.
• Work collaboratively within a large Agile development team.

Work Experience and Job Skills:

• Two (2) or more years of experience in data science, computer vision, image analysis, advanced analytics, machine learning, biometrics, or related technical work is required.
• Experience developing, training, fine-tuning, evaluating, or deploying machine-learning or deep-learning models for computer vision, image analysis, or related capabilities.
