Battery Systems Engineer

Primary Responsibilities

• Design a new battery pack (cell chemistry selection, module and pack architecture, BMS) purpose-built for a continuous, high-uptime datacenter duty cycle.
• Define cycle life, calendar life, and thermal management targets appropriate for continuous or near-continuous stationary operation.
• Define pack-level safety architecture aligned with stationary storage standards (e.g., UL 9540, UL 9540A, NFPA 855).
• Work with the Mechanical/Thermal Engineer to design the pack for a datacenter rack or adjacent enclosure form factor.
• Define BMS requirements and interfaces to the power converter and rack-level controls.
• Support test planning and execution for pack-level validation.
• Required Qualifications:
• Bachelors’ in Electrical, Mechanical, or Chemical Engineering
• 5+ years in battery pack or BMS design.
• Experience with high-voltage (400V+) lithium-ion battery pack design, including module architecture and BMS integration.
• Working knowledge of battery safety and abuse testing principles.
• Preferred Qualifications:
• Direct experience with stationary energy storage systems and associated certification standards (UL 9540/9540A).
• Experience developing a battery system from early concept through a first production design.
• Familiarity with NMC/Si or similar high-energy-density cell chemistries.
