What does a high voltage battery system engineer do?

A High Voltage Battery System Engineer is responsible for designing, developing, and testing battery systems used in electric vehicles and other high-voltage applications. Their work includes ensuring the safety, reliability, and efficiency of battery packs, as well as integrating battery management systems and collaborating with other engineering teams. They analyze system requirements, select appropriate battery technologies, and oversee validation and troubleshooting throughout the product lifecycle.

What are the key skills and qualifications needed to thrive as a high voltage battery system engineer?

To thrive as a High Voltage Battery System Engineer, you need a solid background in electrical engineering, energy storage systems, and battery technologies, typically supported by a relevant degree. Familiarity with simulation tools (such as MATLAB/Simulink), battery management systems (BMS), and safety certifications like ISO 26262 is crucial. Strong problem-solving, teamwork, and effective communication skills help you collaborate on complex projects and troubleshoot system issues. These skills are vital for ensuring safe, efficient, and innovative battery solutions in demanding automotive and industrial applications.

What are some common challenges faced by high voltage battery system engineers when integrating battery systems into electric vehicles?

High Voltage Battery System Engineers often encounter challenges related to thermal management, ensuring battery safety, and optimizing system performance during integration into electric vehicles. Balancing high energy density with safety requirements, mitigating risks of thermal runaway, and ensuring compatibility with vehicle control systems are typical concerns. Collaboration with cross-functional teams, including mechanical, electrical, and software engineers, is essential to address these challenges and deliver reliable battery solutions. Staying updated with evolving industry standards and best practices is also crucial for success in this role.

What is the difference between High Voltage Battery System Engineer vs Battery Management System Engineer?

AspectHigh Voltage Battery System EngineerBattery Management System Engineer
CredentialsBachelor's/Master's in Electrical or Mechanical Engineering, certifications in battery systemsBachelor's/Master's in Electrical Engineering, certifications in BMS design
Work EnvironmentDesigning and testing high voltage battery packs, collaborating with automotive teamsDeveloping and optimizing BMS software, testing BMS hardware
Industry UsageAutomotive, renewable energy, electric vehicle manufacturingElectric vehicles, energy storage systems, consumer electronics

While both roles focus on battery technology, the High Voltage Battery System Engineer oversees the entire battery pack design and integration, whereas the Battery Management System Engineer specializes in developing the software and hardware that monitor and control battery performance. Both roles are essential in electric vehicle development and often collaborate closely.

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.
Pack Performance Engineer
Battery Systems / Pack Engineering
Department: Battery Systems / Pack Engineering
Reports to: Head of Battery Systems Engineering (or Pack Engineering Lead)
Level: Senior / Staff Engineer
Location: United States (site aligned to Gotion's North America engineering footprint)
Role Summary
The Pack Performance Engineer owns the technical bridge between cell, BMS, and vehicle: defining and validating how a battery pack performs across its power boundaries, thermal envelope, and system requirements. This is a hybrid role that sits deliberately at the intersection of three disciplines - BMS/controls, systems engineering, and pack hardware/thermal - rather than living entirely inside one. You will define power and SOC/SOP limits and see them through to vehicle integration, translate performance requirements into validated system attributes, and own pack-level thermal and hardware performance from design through DVP.
Core Focus Areas
1. BMS Interface, Power Limits & Vehicle Integration
  • Define battery charge/discharge current limits, combining SOC, temperature, and cell capability to establish accurate power boundaries
  • Own SOC estimation and SOP (state of power) algorithm inputs and validation
  • Lead cell balancing strategy and isolation measurement verification
  • Drive BMS and Vehicle Control Unit (VCU) integration, ensuring pack performance data and limits are correctly interpreted at the vehicle level
  • Support functional safety testing and requirements across chemistries (e.g. NCM, LFP)
  • Assess the impact of production ramp, design changes, and process changes on battery system performance

2. Battery System Requirements & Performance Validation
  • Translate electrified-powertrain architecture and performance targets into clear, traceable battery system requirements
  • Own performance-attribute definition and specification across the battery system
  • Build and maintain functional safety traceability from requirement to validation
  • Lead systems-level validation planning and execution across battery systems, requirements, and vehicle integration
  • Partner with powertrain, controls, and vehicle integration teams to keep requirements and validation evidence aligned

3. Pack Hardware Performance & Thermal Management
  • Own pack-level performance evaluation: available power, internal resistance, and thermal performance
  • Provide pack performance input into BMS configuration
  • Lead battery performance testing including thermal cycling, thermal runaway characterization, and DVP (Design Verification Plan) execution
  • Support custom high-voltage battery pack design, prototype build, and validation
  • Own pack thermal / cooling system development, from concept through validated performance
  • Analyze capacity, DCIR, cell-disconnect behavior and other pack-level performance data to inform design decisions

Required Experience & Qualifications
  • Bachelor's or Master's degree in Electrical Engineering, Mechanical Engineering, or a related field
  • 7+ years of experience in battery systems, BMS, or pack engineering at an EV OEM or battery systems supplier
  • Hands-on experience with SOC/SOP estimation, cell balancing, and isolation measurement
  • Demonstrated experience defining charge/discharge current limits and power boundaries across SOC, temperature, and cell capability
  • BMS and Vehicle Control Unit (VCU) integration experience
  • Experience defining battery system requirements and performance attributes, with functional safety traceability
  • Experience with pack thermal design and validation - thermal cycling, thermal runaway, and DVP
  • Experience with high-voltage battery pack design, prototyping, and validation
  • Working familiarity with multiple cell chemistries (e.g. NCM, LFP)
  • Strong cross-functional collaboration skills across systems, controls, hardware, and vehicle integration teams

Preferred
  • A demonstrated "T-shaped" background spanning both BMS/controls and pack hardware/thermal domains, rather than depth in only one
  • Experience in a high-volume EV production environment, including support through production ramp
  • Direct ownership of functional safety (ISO 26262) traceability from requirement to validation
  • Prior experience at an EV OEM or battery systems integrator (e.g. supporting passenger, commercial, or energy storage platforms)

This role profile reflects a converged target persona validated against real market benchmarks across BMS/vehicle-integration, systems/requirements, and pack-hardware/thermal backgrounds. It is intended as a working draft for hiring-manager review before search begins.
