Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Pack Performance Engineer - **Company:** Gotion, Inc. - **Location:** Irvine, United States - **Experience:** Expert - **Salary:** $130,000.0 - $160,000.0 - **Contract:** Permanent contract - **Skills:** Systems Engineering, Software Requirements Analysis, Performance Testing - **Published:** August 25, 2026 - **Apply:** https://www.dice.com/job-detail/932df538-0d7b-49ac-bdcd-462ddf0a5583 ## About the Role * 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. ## Description 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 ## Related Videos - [Frontend Performance Testing in practice](https://www.wearedevelopers.com/videos/8-frontend-performance-testing-in-practice) - [Model Based Systems Engineering in an Agile Product Development Process](https://www.wearedevelopers.com/videos/68-model-based-systems-engineering-in-an-agile-product-development-process) - [From Vibe Coding to Viable Code with Spec-Driven Development](https://www.wearedevelopers.com/videos/100216-from-vibe-coding-to-viable-code-with-spec-driven-development) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [The future of automotive mobility: Upcoming E/E architectures, V2X and its challenges](https://www.wearedevelopers.com/videos/374-the-future-of-automotive-mobility-upcoming-e-e-architectures-v2x-and-its-challenges) - [Measure and improve frontend performance by using test automation](https://www.wearedevelopers.com/videos/719-measure-and-improve-frontend-performance-by-using-test-automation) ## Related Articles - [How software is steering vehicle technology](https://www.wearedevelopers.com/magazine/515-how-software-is-steering-vehicle-technology) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [How to Write a CV and Interview if You Don't Fully Qualify For The Job](https://www.wearedevelopers.com/magazine/183-how-to-write-a-cv-and-interview-if-you-don-t-fully-qualify-for-the-job) - [A Guide to Green Tech and Green IT Careers](https://www.wearedevelopers.com/magazine/374-a-guide-to-green-tech-and-green-it-careers) - [A call for Guest Writers for the WeAreDevelopers Magazine](https://www.wearedevelopers.com/magazine/648-a-call-for-guest-writers-for-the-wearedevelopers-magazine) - [The Prompt Engineer ✍️](https://www.wearedevelopers.com/magazine/216-the-prompt-engineer)
