Software Architect - Battery Management Systems

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. Due to our continued growth we are now recruiting for a Software Architect – Battery Management Systems to be based at our customer’s site in Coventry.  

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 Software Architect, you will lead the design and integration of advanced software architectures for next-generation battery management systems. You’ll define control strategies, software interfaces, and diagnostic frameworks across SDU Controls, Cell Supervisory Controllers (CSC), and WGM platforms. Your expertise will ensure robust, scalable, and safety-compliant software solutions that drive performance, reliability, and innovation across electrified powertrains.

Area of Responsibility                

Software Architecture & Design

• Define and evolve the software architecture for BMS control systems across embedded platforms


• Develop scalable software integration strategies for SDU, CSC, and WGM units


• Optimize software performance across thermal, electrical, and safety domains

• Requirements Engineering & Traceability

• Translate system-level requirements into detailed software specifications and interface definitions


• Ensure full traceability from stakeholder inputs through design, implementation, and validation using tools like IBM DOORS or Polarion


• Support functional decomposition and model-based design using MATLAB/Simulink or SysML

• Integration Strategy & Technical Leadership

• Lead cross-functional teams in software development, controls engineering, and validation


• Define communication protocols (CAN, LIN, SPI), timing constraints, and fault-handling logic


• Oversee HIL validation, software-in-the-loop (SIL) testing, and failure mode simulations

• Compliance & Stakeholder Engagement

• Ensure software compliance with ISO 26262 and other functional safety standards


• Collaborate with internal teams, suppliers, and platform owners to align on software architecture goals


• Influence software roadmap decisions and contribute to long-term platform scalability

 Key Experience 

• Bachelor’s or Master’s degree in Software Engineering, Electrical Engineering, or related field


• Extensive experience in embedded software architecture, control systems, or BMS software integration


• Strong proficiency in real-time embedded systems, control algorithms, and communication protocols


• Experience with model-based development tools (MATLAB/Simulink, SysML) and software documentation platforms


• Familiarity with software versioning, CI/CD pipelines, and agile development practices
