Battery Pack Architect M/F

Team: Product Team

Location: Grenoble, Auvergne-Rhône-Alpes

Commitment: CDI / Permanent position

Workplace Type: onsite

Main responsibilities :

1. System Architecture Definition

• Define the overall battery pack architecture, including:
• Electrical topology (series/parallel configuration, HV/LV interfaces)
• Mechanical concept (modules integration, pack integration, pack enclosure design)
• Busbar routing
• Thermal architecture
• Ensure consistency between cells, BMS, power electronics, and system-level requirements
• Drive architectural trade-offs considering performance, cost, risk, manufacturability (ergonomic, value chain, process flow chart) and industrial constraints (existing means compatibility)

 2. Requirements & Performance Management

• Define and cascade system requirements
• In charge of design justification document as well as its integration into PLM
• Ensure requirements traceability across the system
• Define and monitor key performance indicators (KPIs) for the battery pack

3. Multi-Domain System Integration

• Ensure proper integration of all subsystems:
• Cells
• BMS
• Thermal system
• High-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 & Compliance

• Integrate safety constraints from early design stages:
• Define mitigation strategies (detection, isolation, protection mechanisms)
• Ensure compliance with relevant standards and regulations

5. Technical Leadership & Risk Management

• Identify and manage technical risks across the system
• Drive key trade-offs (cost vs performance vs safety)
• Lead architecture and design reviews
• Support high-level product and technical decisions

Requirements :

• 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 design
• Good understanding in battery pack main characteristics sizing, thermal management, and system-level validation (components to full battery pack)
• Familiarity with the simulation approach and DFMEA
• Functional safety fundamentals (HARA, ASIL allocation)
• Knowledge of CATIA V5/SolidWorks (system & electrical layout), and MATLAB/Simulink (pack performance simulation
