Sr. Diagnostics Engineer

Location: Bangalore/Pune

Department: ePowertrain

Employment Type: Full-Time

Experience: 5-8 Years

Role Family: Diagnostics / FUSA / Calibration

Role Overview

Responsible for diagnostics engineering support for ePowertrain features under senior technical guidance. The role develops and maintains diagnostic requirements, DTC definitions, fault reaction matrices, UDS service inputs, validation support artefacts, issue trackers, and release evidence for powertrain controls and electrified propulsion systems.

Primary Focus Areas

- Diagnostic requirement development for VSC, PCM, TCM, BMS, HVJB, inverter, EDU, charging, DC-DC, thermal, and vehicle-level functions.
- DTC definition, fault detection conditions, enable criteria, debouncing, failure reactions, replacement values, service routines, and data identifiers.
- Support for network signal finalisation, diagnostic data logging, service tool inputs, validation coverage, and defect analysis.
- Documentation quality, traceability, open issue tracking, supplier query support, and milestone release readiness.

Key Responsibilities

- Analyse customer, system, software, safety, service, and validation inputs to develop and maintain diagnostic requirements.
- Prepare DTC definitions, fault reaction matrices, diagnostic interface details, DID inputs, routine control needs, and validation acceptance criteria.
- Support diagnostic validation across MiL, SiL, HiL, PiL, rig, dyno, and vehicle stages by reviewing test cases and analysing defects.
- Coordinate with systems, controls, embedded software, calibration, validation, FUSA, cybersecurity, service, supplier, and vehicle integration teams.
- Track diagnostic open points, requirement gaps, validation defects, supplier responses, release actions, and change impact items through closure.
- Review diagnostic logs, fault memories, measured signals, network traces,



and defect reports to support root cause analysis.
- Maintain requirement traceability, issue logs, review actions, and release support documentation for programme milestones.
- Escalate diagnostic risks, interface conflicts, validation gaps, and supplier dependencies to diagnostics leads and programme stakeholders.

Required Skills & Experience

- Positive understanding of automotive diagnostics, UDS, DoIP, DTC handling, fault reactions, CAN/CAN FD/Ethernet networks, and EV/HEV system interfaces.
- Experience in diagnostic requirements, functional specification support, validation support, issue tracking, and diagnostic log analysis.
- Working knowledge of CANoe, CANape/INCA, service tools, data logging, Jira/Azure DevOps, and requirement management tools.
- Ability to work across cross-functional teams and maintain structured diagnostic documentation under delivery timelines.
