Data Scientist (New Grad /Early Career)

Xonar Technology Inc. develops security screening tools, including TruePort and TrueScan. The early-career Data Scientist will train, test, and improve machine learning models using sensor and X-ray data, validate system updates, and help teams monitor and understand detection performance.

Responsibilities:

• Collect, label, and organize sensor and X-ray imaging data from lab tests and field deployments
• Train and evaluate machine learning models for TruePort and TrueScan, and track metrics such as precision, recall, and false-positive rate
• Debug model behavior by investigating missed detections and nuisance alarms, then working with engineers to fix root causes
• Design and run tests to validate model and software updates before release
• Build dashboards that track detection performance, throughput, and system health for internal teams and customers
• Use AI and scripting to automate repetitive data, labeling, reporting, and testing workflows
• Join customer conversations to explain performance, answer technical questions, and gather feedback
• Document datasets, experiments, and findings so the team can build on them
