Overview
System Architect - Battery Management System at Tata Technologies. Based at our customer’s site in Gaydon.
At Tata Technologies we make product development dreams a reality by designing, engineering and validating the products of tomorrow for the world’s leading manufacturers. Our Embedded Systems Solutions department (ESS) encompasses all activities outlined under the Automotive SPICE (ASPICE) process framework, including systems engineering, software engineering, coding, and all levels of functional testing. Beyond core development, ESS also integrates critical supporting processes such as project management, risk assessment, functional safety, and cybersecurity, ensuring compliance with ASPICE standards and delivering reliable, secure, and high-quality embedded systems & solutions.
The Role
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.
Area of Responsibility
* 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
* 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
* 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
Knowledge / Experience
* 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
In return for bringing your expertise to our business we offer a competitive salary along with excellent benefits including:
* Pension Scheme – We match employee contribution up to 5% of salary
* Tata Jaguar Land Rover Privilege Scheme - up to 20% off new JLR vehicles
* Health Assured – Employee Assistance Program
* Health Shield – Private Health Cash Plan
