Job summary

QuantumScape is seeking a Battery / Pack Systems Engineer to own everything from cell to pack for a PSU+BBU rack integrated platform. You will design the mechanical assembly, BMS topology, thermal management, safety analyses, and age testing to translate evolving cell specs into robust pack designs.

This onsite role requires collaborating with cell development, firmware, and power electronics teams to meet data-center duty cycles and certification goals, including UL 1973 and UL 9540A, while

Qualifications

• 8+ years in battery pack design and at least one product through prototype validation or production
• Hands-on BMS hardware architecture experience (specify topology and component selection)
• Cell characterization and modeling skills (impedance spectroscopy, capacity fade, thermal characterization)
• Experience with safety standards, UL 1973; UL 9540A exposure strongly preferred
• Pack-level thermal modeling and mechanical design (SolidWorks, Creo); thermal simulation a plus
• Comfortable working with evolving cell specs and making design decisions with incomplete data

Responsibilities

• Design the cell-to-pack mechanical assembly within the PSU+BBU enclosure
• Architect the BMS hardware topology and specify protection FET sizing and interfaces
• Develop and tune SOC/SOH estimation algorithms for solid-state chemistry
• Co-develop charge/discharge profiles with firmware, optimize for data-center duty cycles
• Design the thermal interface and heat paths in collaboration with engineers
• Conduct pack-level FMEA and safety analysis; define abuse test protocols
• Design accelerated aging test protocols for data-center duty cycles
• Serve as liaison to the cell development team to translate pack requirements to cell specs
• Support UL 1973 and UL 9540A safety certification activities
