You drive key design decisions by balancing electrochemical, electrical, thermal, mechanical, and safety constraints to deliver a solution that is safe, high-performing, manufacturable, and cost-effective.You act as a cross-functional technical leader and the main guarantor of the system-level vision.Main responsibilities : 1.

System Architecture DefinitionDefine the overall battery pack architecture, including:Electrical topology (series/parallel configuration, HV/LV interfaces)Mechanical concept (modules integration, pack integration, pack enclosure design)Busbar routingThermal architectureEnsure consistency between cells, BMS, power electronics, and system-level requirementsDrive architectural trade-offs considering performance, cost, risk, manufacturability (ergonomic, value chain, process flow chart) and industrial constraints (existing means compatibility) 2.

Requirements & Performance ManagementDefine and cascade system requirementsIn charge of design justification document as well as its integration into PLMEnsure requirements traceability across the systemDefine and monitor key performance indicators (KPIs) for the battery pack3.

Multi-Domain System IntegrationEnsure proper integration of all subsystems:CellsBMSThermal systemHigh-voltage components (contactors, fuses, etc.)Manage critical interfaces (electrical, thermal, mechanical, communication)Guarantee system behavior under all operating conditions (normal and fault cases)4.

Safety & ComplianceIntegrate safety constraints from early design stages:Define mitigation strategies (detection, isolation, protection mechanisms)Ensure compliance with relevant standards and regulations5.

Technical Leadership & Risk ManagementIdentify and manage technical risks across the systemDrive key trade-offs (cost vs performance vs safety)Lead architecture and design reviewsSupport high-level product and technical decisionsRequirements : Master’s degree in Electrical Engineering, Systems Engineering, or equivalent.Minimum of 5 years of experience in battery system architecture, with at least 5 years owning system architecture on complete pack programs.An experience with EV OEMs, Tier 1 suppliers, or pack integrators is preferred.Proven greenfield program experience (building a product from scratch).Fluent English mandatory.Willingness to travel to customers and suppliers internationally.Knowledge of applicable standards: IEC 62619, UN 38.3, GB38031, ECE R100, ISO 26262 fundamentals.Required management tools: DOORS, Polarion, or Jama.

JIRA or an equivalent for project tracking.Proven knowledge in high-voltage battery pack design and development and battery pack mechanical designGood understanding in battery pack main characteristics sizing, thermal management, and system-level validation (components to full battery pack)Familiarity with the simulation approach and DFMEAFunctional safety fundamentals (HARA, ASIL allocation)Knowledge of CATIA V5/SolidWorks (system & electrical layout), and MATLAB/Simulink (pack performance simulationWe may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information.

These tools assist our recruitment team but do not replace human judgment. xuezdbg
