Candidates will work closely with feature teams to generate diagnostic readiness data required for software build acceptance and program milestones.

Area of Responsibility

• Diagnostic Protocols & Network Debug
  • Perform verification and validation of diagnostic services based on UDS (ISO 14229).
  • Debug and analyze communication on CAN, CAN-FD, and DoIP networks.
  • Validate Transport Layer behaviour and message flow for diagnostics-related ECUs.
  • Investigate issues related to DTCs, session handling, security unlocking, flash sequences, etc.
  • Capture and interpret network logs to support root-cause analysis.
• Tools & Test Execution
  • Execute diagnostic test cases using industry-standard tools such as Vector CANoe / CANalyzer, Wireshark, Corvus (or equivalent EOL/diagnostics tools).
  • Develop or update CANoe panels, CAPL scripts, and trace configurations where required.
  • Perform log analysis and generate findings, defects, and recommendations.
  • Support automation initiatives for regression testing and data generation.
• Diagnostics & EOL Specification Understanding
  • Interpret and validate diagnostic specifications, EOL/production test requirements, and ECU interface documents.
  • Ensure diagnostic readiness for software builds and support Build Acceptance Test (BAT) cycles.
  • Cross-check ECU implementation against specification for UDS services, DID structures, routines, and DTC behaviour.
  • Collaborate with manufacturing/EOL teams to align diagnostic behaviour with plant requirements.
• Additional Responsibilities
  • Generate structured V&V evidence, data reports, and build readiness metrics for program leadership.
  • Work with feature owners, ECU suppliers, and integration teams to close diagnostic issues.
  • Contribute to continuous improvement of diagnostic validation processes and toolchains.

Knowledge / Experience

• Strong hands-on experience with UDS, CAN, CAN-FD, DoIP, and Transport Layer diagnostics.
• Practical exposure to Vector tools, Wireshark, Corvus, and diagnostic scripting.
• Good understanding of automotive diagnostics architecture, DTC structures, service flows, and ECU communication.
• Ability to perform deep dive debugging and interpret logs from complex systems.
