Job summary

ALSO is seeking a Battery Systems Engineer in Palo Alto to own the battery system architecture and analytics that shape the vehicle’s energy strategy. You’ll influence cell selection, pack topology, charging strategy, and thermal behavior while coordinating with cross-functional teams to meet performance, range, and cost targets.

You will build and refine cell- and pack-level models in Python, MATLAB, and Simulink, translate data into design targets, and define test plans that bridge analysis

Qualifications

• 8+ years in battery systems engineering with ownership of battery architecture and requirements on a shipped product
• Deep understanding of lithium-ion cell behavior, including electrochemical operating principles, thermal characteristics, degradation mechanisms
• Hands-on modeling expertise (Python, MATLAB, Simulink) building equivalent circuit models, thermal networks, degradation behavior
• Experience developing or validating duty cycles for EV or electrified powertrain applications
• Proven ability to translate cell and pack behavior into BMS hardware and firmware requirements
• Fluent enough in controls and embedded systems to be technically credible
• BS/MS in Electrical Engineering, Mechanical Engineering, or related field
• Bonus: Cell characterization experience (HPPC, OCV curves, degradation cycling) and familiarity with SOC/SOH/SOE state estimators
• Bonus: Advanced simulation tools (Ansys, Fluent, Icepak) and fast-charge protocol development

Responsibilities

• Own the analytical foundation behind the battery system and lead trade studies across chemistry, topology, SOC window, cell selection, and operating limits
• Build and advance cell- and pack-level electrical, thermal, and degradation models using real-world data
• Define how the battery operates including charging strategy, user-facing behavior, and end-of-life strategy
• Own cell evaluation and down-selection, define characterization test plans and translate cell behavior into pack-level inputs
• Define battery system requirements including protection thresholds, thermal limits, and fault detection, partnering with BMS teams
• Close the loop between analysis and hardware with test case development and model-to-measurement correlation
• As an early member, set rigorous standards for the battery engineering team
