• Performed pre-analysis of ECU flashing and regression test results, identifying failures and categorizing issues based on software, test setup, configuration
• Investigated test failures and performed root cause analysis and pre analysis using Wireshark for Ethernet and CARMEN for CAN and FlexRay protocols.
• Analysed UDS diagnostic sequences (ISO 14229) and communication traces to identify and classify ECU flashing failures
• Collaborated with cross-functional teams to distinguish between software defects, test environment issues, and vehicle communication failures, ensuring accurate defect classification.
• Documented findings in the integrate application and created defect tickets in Octane for confirmed software issues.
• Created detailed defect reports in Octane including failure evidence, log analysis results, root cause observations
• Ensured accurate tracking and timely resolution of defects.
• Performed regression result analysis and validation of resolved defects to ensure software stability

HIL Validation Engineer - German OEM - BMS at Karnex Software Solutions (2022-01 – 2024-05)

• Reviewed software requirements and created software test specifications and software test cases.
• Hands-on experience in MATLAB, Simulink, and Stateflow for understanding software code flow, signal interactions, state logic, and interface behavior during Software Integration Testing.
• Validated multiple software interfaces by analyzing MATLAB/Simulink and Stateflow model behavior and comparing expected vs actual signal outputs.
• Supported Software Integration Testing by reviewing Simulink and Stateflow models, understanding functional logic, state transitions, and verifying interface-level communication.
• Responsible for requirement-based test case writing, modification, and execution for BMS features such as Cell Balancing, Under Voltage, Over Voltage, SOC, and battery monitoring.
• Performed HIL-based test execution using VT System and vTESTstudio to verify correct software behavior according to requirements, test descriptions, and expected system responses.
• Executed and analyzed test cases for BMS and EV-related functions.
• Created, updated, and maintained software test cases, software test design specifications, and software test reports as part of validation work products.
• Uploaded test cases, test specifications, and test reports in the In-Step tool to maintain bidirectional traceability between requirements, test cases, and test results.
• Performed structured test execution, regression testing, and test result analysis using HIL test reports and captured logs.
• Analyzed test failures and documented defects with proper evidence, including failed steps, expected vs actual results, test logs, and observations.
• Reported defects in In-Step and supported defect tracking, review, clarification, and closure activities.
• Modified test specifications and test cases based on review comments, defect analysis, and requirement updates.
• Interacted with requirement owners and development teams to clarify requirement ambiguity, test scope, expected behavior, and validation coverage.
• Gained working understanding of ASPICE, V-model, requirement traceability, validation process, and ISO 26262 concepts from a software validation perspective.
