Job description

At Tata Technologies we make product development dreams a reality by designing, engineering and validating the products of tomorrow for the world's leading manufacturers. Due to our continued growth we are now recruiting for a Diagnostics V&V Engineer to be based at our customer's site in Gaydon.

Our Embedded Systems Solutions department (ESS) encompasses all activities outlined under the Automotive SPICE (ASPICE) process framework, including systems engineering, software engineering, coding, and all levels of functional testing. Beyond core development, ESS also integrates critical supporting processes such as project management, risk assessment, functional safety, and cybersecurity, ensuring compliance with ASPICE standards and delivering reliable, secure, and high-quality embedded systems & solutions.

Role Summary

The Diagnostic V&V Engineer will be responsible for validating and verifying vehicle diagnostic functionality across current and upcoming vehicle programs. The role focuses on UDS-based diagnostics, in-vehicle networks, and ensuring EOL/production readiness. Candidates will work closely with feature teams to generate diagnostic readiness data required for software build acceptance and program milestones.

Dimension of function

The Diagnostic V&V Engineer will produce the diagnostic readiness data needed to assess build health and support program sign-offs for current vehicle platforms. Their work directly ensures software maturity and prevents late-stage diagnostic issues in vehicle production.

1. 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 behavior 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.
2. 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.
3. 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 behavior.
   • Collaborate with manufacturing/EOL teams to align diagnostic behavior 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.

• 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.
• Familiarity with EOL test flow, production constraints, and plant-level diagnostic checks.
