About the role
- This is a highly cross-functional systems role spanning battery engineering, vehicle architecture, controls, thermal systems, and product definition.
- The salary for this position ranges from $150,000 - $255,000 per year, depending on experience and qualifications.
Responsibilities
- Own the analytical foundation behind the battery system.
- Lead trade studies across chemistry, pack topology, SOC window, cell selection, and operating limits - translating engineering decisions into cost, range, performance, and cycle life tradeoffs that drive product and business direction
- Build and advance cell- and pack-level electrical, thermal, and degradation models.
- Develop battery duty cycles from real-world usage data and mission profiles, correlate models against measured data, and use them to set architecture decisions, design targets, and operating limits.
- Own cell evaluation and down-selection. Define characterization test plans, interpret performance and degradation data, and translate cell behavior into pack-level model inputs, design constraints, and BMS operating envelopes.
- Partner with BMS hardware, firmware, and controls teams to ensure what gets implemented reflects real-world operating realities - you bring the use case context and cell behavior constraints they need to succeed.
- Close the loop between analysis and hardware. Define test cases, support bench and vehicle-level bring-up, and drive model-to-measurement correlation across electrical, thermal, and degradation domains.
- 8+ years in battery systems engineering with demonstrated ownership of battery architecture and requirements on a shipped product - not program support, not analysis in isolation
- Deep understanding of lithium-ion cell behavior: electrochemical operating principles, thermal characteristics, degradation mechanisms, and how these translate into real-world duty cycle and pack design constraints
- Experience developing or validating duty cycles for EV or electrified powertrain applications and translating mission profiles into battery requirements and operating limits
Requirements
- How you work - your rigor, your speed, your standards - sets the bar for the engineers who come after you.
- Hands-on modeling expertise (Python, MATLAB, Simulink): equivalent circuit models, thermal networks, degradation behavior, pack-level simulation.
- You have built these from scratch, not just run them
- Experience with advanced simulation tools (Ansys Mechanical, Fluent, Icepak, or equivalent).
- Familiarity with BMS state estimation algorithms (SOC, SOH, SOE) and how they interface with controls.
- Familiarity with requirements management tools.
Compensation
- Experience with advanced simulation tools (Ansys Mechanical, Fluent, Icepak, or equivalent).
- Background in small EVs, two-wheelers, or light electric mobility platforms.
- Fast-charge protocol development and optimization.
- Familiarity with BMS state estimation algorithms (SOC, SOH, SOE) and how they interface with controls.
- Familiarity with requirements management tools.
- Strong business acumen - comfortable framing engineering tradeoffs in terms of cost, program risk, and product impact.
Benefits
- Robust health coverage - excellent health, dental, and vision insurance covered up to 100% by ALSO, with FSA & HSA options
- One Medical membership and dedicated insurance advocates
- Rich fertility and family-building benefits with Progyny
- Flexible time off
