Job summary

Gotion Inc. in Irvine, CA is seeking a Staff/Principal Battery Systems Engineer to lead system-level design for high-voltage battery development and integration.

You will translate customer requirements into battery-system targets, own requirements allocation, and guide DFMEA and validation planning across cell, pack, BMS, and vehicle interfaces. You will coordinate cross-functional teams, set performance targets, and mentor engineers while supporting ramp-up and field issue resolution to ensure

Qualifications

• BS, MS, or PhD in Systems, Electrical, Mechanical, Automotive, Chemical Engineering, or a related discipline.
• 7+ years of experience in EV batteries, high-voltage battery systems, electrified powertrains, or related automotive systems.
• Strong understanding of HV battery architecture, including cells, pack mechanical systems, HV/LV electrical systems, thermal management, charging, BMS interfaces, and vehicle integration.
• Demonstrated experience translating vehicle or OEM requirements into battery-system requirements and technical targets.
• Strong understanding of battery performance and the interaction between cell capability, voltage, current, SOC, temperature, aging, thermal performance, and vehicle demand.
• Proven ability to integrate multiple engineering disciplines and make sound system-level technical decisions.
• Experience with requirements, architecture, validation, vehicle integration, or technical issue resolution for complex automotive systems.
• Strong technical problem-solving, data-analysis, and root-cause capability.
• Strong communication skills and ability to work directly with OEM engineering organizations.

Responsibilities

• Serve as the system-level technical lead for high-voltage battery development and integration.
• Translate vehicle and customer requirements into battery-system and subsystem requirements across cell, mechanical, electrical, thermal, BMS interfaces, validation, and manufacturing.
• Own requirement decomposition, allocation, traceability, verification, and system-level change impact.
• Define and integrate battery performance targets, including energy, power, voltage, current, charging, temperature, aging, and safety limits.
• Lead cross-functional architecture and technical trade studies across performance, safety, durability, packaging, cost, and manufacturability.
• Integrate inputs from Cell, Mechanical, Electrical, Thermal, CAE, Validation, Manufacturing, and customer engineering teams into a consistent system solution that meets customer requirements.
• Lead the technical interface with BMS and controls teams for battery operating limits, capability maps, sensing, diagnostics, protection thresholds, and other constraints.
• Lead system DFMEA, technical risk reviews, and system-level design reviews.
• Define system verification methods and support DVP&R and validation planning.
• Analyze cell, pack, BMS, simulation, test, and vehicle data to identify system limitations and root causes.
• Lead cross-functional technical issue resolution and drive corrective actions to closure.
• Ensure consistency between customer specifications, Gotion requirements, design releases, validation plans, and production-intent configurations.
• Support vehicle launch, production ramp-up, and field issue resolution.
• Help establish battery systems engineering practices and mentor engineers across programs.
