What is performance engineering?

Performance engineering is a discipline in software and systems development focused on ensuring applications and systems meet required speed, scalability, and stability standards. It involves analyzing, designing, testing, and optimizing performance throughout the software development lifecycle. Performance engineers use specialized tools and methodologies to detect bottlenecks, simulate real-world loads, and recommend improvements. Their goal is to deliver reliable, high-performing products to end users.

How does a performance engineer typically collaborate with development and operations teams to resolve application bottlenecks?

Performance Engineers play a vital role in bridging the gap between development and operations teams. They work closely with developers to analyze application code and identify potential performance issues early in the development lifecycle. Additionally, they partner with operations teams to monitor system performance in production, interpret logs, and recommend infrastructure or configuration changes. This collaborative approach helps ensure that performance bottlenecks are identified and addressed quickly, leading to more reliable and scalable applications.

What are the key skills and qualifications needed to thrive as a performance engineer, and why are they important?

To thrive as a Performance Engineer, you need strong analytical abilities, expertise in software performance testing, and a background in computer science or a related field. Familiarity with tools like JMeter, LoadRunner, APM solutions, and scripting languages is typically required, along with relevant certifications such as ISTQB Performance Testing. Exceptional problem-solving skills, attention to detail, and effective communication help you identify bottlenecks and collaborate with development teams. These skills are crucial for ensuring applications meet performance standards and deliver a seamless user experience.

What is the difference between Performance Engineering vs Performance Testing?

AspectPerformance EngineeringPerformance Testing
FocusDesigning, developing, and implementing strategies to ensure system performance throughout the development lifecycleExecuting tests to measure system performance under specific conditions
ActivitiesPerformance planning, monitoring, optimization, and capacity planningLoad testing, stress testing, and benchmarking
Skills & CertificationsPerformance testing tools, scripting, monitoring, performance analysisPerformance testing tools, scripting, test execution
Work EnvironmentCollaborates with developers, architects, and operations teamsPrimarily testing teams and QA departments

Performance Engineering involves proactive strategies to optimize system performance throughout development, while Performance Testing focuses on evaluating system performance through specific tests. Both roles require similar skills but differ in scope and objectives, with Performance Engineering being more comprehensive and ongoing.

How much do performance engineers make in the US?

Performance engineers in the US typically earn between $80,000 and $130,000 annually, depending on experience, location, and industry. Senior roles or those with specialized skills in tools like JMeter or LoadRunner can command higher salaries, especially in tech hubs.

What do you need to be a performance engineer?

Performance engineers need a strong understanding of software architecture, performance testing tools, and scripting languages like Python or Java. They often have a background in computer science or engineering, experience with performance testing tools such as JMeter or LoadRunner, and knowledge of system monitoring and analysis. Certifications in performance testing or related fields can also be beneficial.

Job description

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.
