BMS System Architect – Functional Integration & Hardware Delivery
Location: Midlands, UK
Employment Type: Full-Time
Department: Systems Architecture – Battery Management Systems
Role Overview
As a BMS System Architect, you will define and oversee the end-to-end architecture for cutting‑edge battery management systems, integrating control, hardware, and diagnostic components. Your technical leadership will shape the interfaces between SDU Controls, Cell Supervisory Controllers (CSC), and WGM hardware to ensure optimal system performance, safety compliance, and integration scalability.
Key Responsibilities
System Architecture & Design
* Define and evolve the holistic architecture of BMS across functional domains and hardware interfaces
* Architect scalable and robust integration schemes for SDU, CSC, and WGM units
* Balance competing requirements including safety, reliability, thermal management, and electrical performance
Requirement Definition & Traceability
* Capture, structure, and decompose high-level system requirements into detailed functional and interface specifications
* Establish traceability from stakeholder inputs through design and verification stages using tools like IBM DOORS or Polarion
Integration Strategy & Technical Oversight
* Guide multidisciplinary teams across software, controls, hardware, and validation functions
* Define integration boundaries, communication protocols, timing requirements, and fault handling mechanisms
* Support validation activities including HIL setup, test case scoping, and failure mode simulations
Stakeholder & Compliance Coordination
* Liaise with internal technical leaders, suppliers, and product owners to align on architecture goals
* Ensure system compliance to standards including ISO 26262 (functional safety) and regulatory frameworks
* Influence platform roadmap decisions and future‑proof system scalability
Required Qualifications
* Master's or Bachelor's degree in Electrical Engineering, Systems Engineering, or related field
* 7+ years of experience in embedded architecture, system‑level design, or BMS integration
* Proven track record architecting complex control systems across hardware and software domains
* Familiarity with CAN, LIN, SPI communication systems and real‑time embedded platforms
* Proficient in modeling and documentation tools (e.g., SysML, MATLAB/Simulink, Enterprise Architect)
Preferred Attributes
* Experience with AUTOSAR architectures and safety‑critical application design
* In‑depth knowledge of lithium‑ion battery technology, cell‑balancing algorithms, and thermal modeling
* Strategic mindset with strong attention to technical detail and cross‑functional collaboration
* Background in automotive, aerospace, or electrification platforms requiring high‑voltage integration
