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
