Software Diagnostics Lead

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 Software Diagnostic Lead to be based at our office in Warwick.

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.

The Role: 

The 

• Lead the end-to-end diagnostics strategy for Software-Defined Vehicle platform across HPCs, zonal controllers, and classic ECUs.  


• Defining the diagnostics architecture (on-board and off-board), own UDS/DoIP/SOME-IP/SOVD integration, and drive manufacturability, serviceability, over-the-air (OTA) update robustness, and regulatory compliance. 


• Identify root causes and failure modes using field data, lab tests, and analytical tools. Develop fault detection, and recovery strategies. Map failure paths and diagnostic coverage in alignment with functional safety standards (ISO 26262, IEC 61508) 


• Ensure system-level diagnostics are accurate, adaptive, and fail-safe. 


• Owning standards, tools, and processes that deliver 100% diagnosability from plant to aftersales. Support rig and vehicle builds with network releases.
