Support for HV operating states, protection requirements, isolation, HVIL, discharge, contactor coordination, fault handling, and service modes.

Interface tracking between HV components, vehicle controllers, network signals, diagnostics, validation teams, and supplier deliverables.

Documentation, traceability, issue closure, validation support, and milestone readiness for HV system releases.

Key Responsibilities

Analyse customer, vehicle, architecture, safety, component, and validation inputs to develop and maintain HV system requirements.

Support definition of HV system operating modes, interface signals, protection logic, diagnostics, degraded operation, and acceptance criteria.

Prepare and maintain functional specifications, interface control documents, requirement traceability matrices, and validation support artefacts.

Coordinate with battery, BMS, HVJB, charger, DC-DC, inverter, EDU, thermal, controls, software, validation, safety, cybersecurity, and supplier teams.

Support review of network signal requirements, diagnostics services, measurement needs, validation plans, test cases, and defect analysis.

Track open issues, change requests, supplier questions, validation gaps, and release actions through closure.

Support MiL,



SiL, HiL, rig, and vehicle validation by confirming requirement coverage and providing system-level technical inputs.

Escalate integration risks, interface gaps, requirement conflicts, and supplier delivery dependencies to senior leads and programme stakeholders.

Required Skills & Experience
