Electrical Engineer - Battery Pack Design

Battery Pack Design Engineer – Electrical

Location: San Francisco

About the role

As an Electrical Engineer on our battery team, you'll own the electrical architecture of advanced lithium-ion systems - from schematics and hardware selection through thermal analysis, validation, and launch - for customers across automotive, aerospace, renewable energy, and industrial markets.

What you'll do

• Define high- and low-voltage distribution, interfaces, and protection systems for battery packs
• Own schematic design - sensors, contactors, fuses, connectors, harnesses, and control electronics
• Select and integrate electronics hardware (current sensors, power electronics, microcontrollers) for safety, performance, and manufacturability
• Perform thermal and power dissipation analysis across environmental and load conditions
• Support circuit design, simulation, and bench testing for measurement, control, and protection
• Drive safety and compliance — DFMEA, functional safety (ISO 26262 or equivalent), UL
• Partner with mechanical, software, and manufacturing teams, and present findings to customers and leadership

What you bring

• 3+ years of system-level design for lithium-ion battery packs or related electrical systems
• 4+ years of engineering experience in automotive, aerospace, or industrial sectors
• Strong electrical system design and schematic capture skills
• Knowledge of thermal management, power dissipation, HV/LV component integration
• Familiarity with HV safety standards, EMC/EMI, grounding/shielding
• BS in Electrical Engineering or related discipline

Preferred

MS/PhD in EE; hands-on BMS, control algorithms, or embedded electronics; ISO 26262; project leadership; battery modeling.

Export-controlled role: candidates must be a U.S. citizen, permanent resident, refugee, or asylee.
