• Analyze telemetry and diagnostic datasets to identify fault patterns, trends, and anomalies.
• Tune diagnostic detection thresholds using real-world fleet data.
• Validate diagnostic algorithm performance based on detection rate, false-positive rate, and diagnostic accuracy .
• Investigate diagnostic failures, false positives, missed detections, and other fault-related issues.
• Support the development and validation of diagnostic monitoring strategies.
• Apply automotive diagnostic standards and protocols including UDS / ISO 14229, DTC Management, OBD-II, and SAE J1979 .
• Work with automotive communication networks including CAN, LIN, and Automotive Ethernet .
• Use Python for data analysis, processing, automation, and visualization.
• Develop scripts and analytical tools to investigate diagnostic and telemetry data.
• Apply C++ knowledge to support diagnostic software and algorithm development.
• Collaborate with software and diagnostic engineering teams to improve diagnostic implementations.
• Work with HIL and SIL testing frameworks to validate diagnostic functionality.
• Support automated diagnostic testing and regression validation.
• Correlate HIL/SIL test results with real-world fleet and telemetry data.
• Drive continuous improvement of diagnostic algorithms using data-driven insights.

Key Requirements
