In this role, you define system-level technical direction, own key architecture decisions, and ensure regulatory and functional safety compliance while serving as the subject-matter expert across firmware, electronics, algorithms, and system integration. You will lead the evolution of multi-generation BMS platforms, guide cross-functional architectural decisions, and ensure solutions are robust, scalable, and aligned with current and future product roadmaps., * Serve as the technical authority for BMS architecture, covering firmware, electronics, sensing, controls, and system integration. * Define and maintain system-level BMS architecture, design patterns, and technical standards across multiple product lines. * Lead technical trade studies that balance safety, performance, cost, manufacturability, and long-term maintainability. * Establish best practices for embedded firmware architecture, hardware abstraction, diagnostics, and fault handling. * Provide expert-level guidance on embedded firmware design, real-time systems, and safety-critical software. * Lead the development and review of core BMS algorithms, including state of charge (SOC), state of health (SOH), state of energy (SOE), cell balancing, protection, diagnostics, and degradation monitoring. * Own the interpretation and application of relevant safety and compliance standards such as UL, IEC, ISO, and functional safety guidance as they relate to BMS design. * Drive system-level requirements decomposition, traceability, and verification strategies to ensure complete coverage and robust performance. * Lead DFMEA, fault tree analysis (FTA), and system-level risk assessments, ensuring mitigation strategies are implemented, verified, and maintained. * Guide the development of end-of-line test strategies, diagnostic coverage, and service tools to support manufacturing and field service. * Ensure BMS designs are manufacturable, testable, and serviceable at scale for long-term product success. * Support long-term sustainment activities, reliability improvements, and continuous improvement initiatives across BMS platforms. * Perform other engineering and technical duties as needed to support product development and lifecycle management., This role focuses on advanced Battery Management System engineering within an embedded systems and electronics environment. You will work with technologies such as embedded firmware, real-time systems, communication protocols (SPI, I2C, CAN, CANOpen, J1939, UDS), and safety and compliance frameworks (UL, IEC, ISO, functional safety guidance). The position involves close collaboration with cross-functional engineering teams, participation in design reviews and risk assessments, and engagement with manufacturing and test engineering to ensure designs are manufacturable, testable, and serviceable at scale. Work is primarily performed in an office and laboratory setting with access to development tools, diagnostic equipment, and test systems for batteries and power electronics. ## Related Videos - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [Playing Pong on a shoulder press machine](https://www.wearedevelopers.com/videos/100140-playing-pong-on-a-shoulder-press-machine) - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [Agent Smith Gets Hardware: Autonomous IoT Hacking From Debug Port to Cloud API](https://www.wearedevelopers.com/videos/100258-agent-smith-gets-hardware-autonomous-iot-hacking-from-debug-port-to-cloud-api) - [Car's are Technology on Wheels - Impact of Software and IT Competence in Automotive](https://www.wearedevelopers.com/videos/780-car-s-are-technology-on-wheels-impact-of-software-and-it-competence-in-automotive) - [When Agents Meet Legacy: Never Change a Running System](https://www.wearedevelopers.com/videos/100320-when-agents-meet-legacy-never-change-a-running-system) ## Related Articles - [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) - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering) - [How software is steering vehicle technology](https://www.wearedevelopers.com/magazine/515-how-software-is-steering-vehicle-technology) - [From developer to manager – what does it take to become an engineering manager?](https://www.wearedevelopers.com/magazine/42-from-developer-to-manager-what-does-it-take-to-become-an-engineering-manager) - [Top-Paying Tech Jobs (with Salaries)](https://www.wearedevelopers.com/magazine/372-top-paying-tech-jobs-with-salaries)
