Job description

Gotion Inc. is based in Silicon Valley, CA, currently building a Manufacturing facility in Manteno, IL and has R&D centers in Ohio, China, Japan and Europe. We innovate in the next generation electric vehicle and energy storage technologies (lithium batteries and related systems) with the aim to accelerate electrified transportation and achieve sustainable development. Gotion is powered by a leading power battery technology company that provides solutions for vehicles including the world's first mass commercial e-bus route.

Gotion is a career destination - we are not simply attempting to just fill another job, but to pursue a dream of global green energy together! We offer outstanding opportunities to individuals seeking an exciting and challenging working environment. Everyone is highly valued and plays a vital role in the growth of our organization.

This position may be filled at the Staff, Senior Staff, or Principal level, depending on the candidate's qualifications, technical depth, and experience.

Key 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.

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.

Preferred / Nice to Have

• Experience with major EV or automotive OEM battery programs.
• Experience at an OEM, battery manufacturer, automotive Tier 1, or EV technology company.
• Experience with BMS hardware and software interfaces.
• Familiarity with battery capability maps, power limits, charging limits, DVP&R, DFMEA, ISO 26262, and requirements-management tools such as DOORS, Jama, or Polarion.
