Department: Energy Platform

Employment Type: Full-Time

Experience: 7-10 Years

Role Family: HV System Engineering

Role Overview

Responsible for system engineering ownership of Battery and Battery Management System functions within the Energy Platform. The role defines and manages requirements, functional behaviour, interfaces, diagnostics, validation strategy, and release readiness for battery pack, BMS, HV safety, charging, power availability, thermal, and vehicle integration functions.

Primary Focus Areas

Battery and BMS requirements covering states, charging, power limits, SOC, SOH, thermal interaction, diagnostics, and protection features.

Interfaces between BMS, battery pack, HVJB, charger, DC-DC, inverter, EDU, VSC, thermal controller, and vehicle networks.

System behaviour for HV safety, isolation, HVIL, contactor coordination, discharge, fault handling, limp-home, and service modes.

Validation readiness across supplier testing, MiL, SiL, HiL, rig, pack-level, and vehicle-level verification activities.

Key Responsibilities

Capture, analyse, decompose, and manage Battery and BMS requirements from vehicle, customer, architecture, safety, charging, thermal, and validation inputs.

Define BMS functional behaviour, operating modes, interface signals, diagnostics, fault reactions, degraded modes, and system acceptance criteria.

Develop functional specifications, interface control documents, requirement traceability, and system integration artefacts for battery and BMS functions.

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

Review battery safety requirements, HV protection concepts, network signal requirements, diagnostic coverage, data logging needs, and validation evidence.

Support verification strategy, test case review, defect triage, root cause analysis,



and release readiness across supplier, rig, HiL, and vehicle environments.

Support functional safety and cybersecurity work products by aligning safety requirements, secure interactions, diagnostics, and degraded operation needs.

Lead change impact assessments and provide system-level technical inputs for programme gateway reviews and supplier release decisions.

Required Skills & Experience

Solid understanding of battery systems, BMS functions, HV safety, charging, contactor coordination, SOC/SOH, thermal limits, diagnostics, and EV integration.

Experience in requirements engineering, system architecture, interface management, validation planning, issue resolution, and release governance.

Knowledge of HV electrical protection, isolation monitoring, HVIL, battery fault handling, charging standards awareness, and data analysis requirements.

Ability to coordinate technical alignment across OEM, supplier, systems, software, safety, thermal, validation, and vehicle integration teams.
