BMS Algorithm Engineer

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 BMS Algorithm Engineer to be based at our customer’s site in Coventry.

The 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.

We are looking for a passionate and experienced BMS Algorithm Developer to lead the design, development, and validation of cutting‑edge battery control algorithms for electric and hybrid vehicle applications. This role is integral to shaping the future of energy storage management across vehicle platforms, ensuring performance, safety, and compliance with global standards.

• Develop robust algorithms for State of Charge (SoC), State of Health (SoH), State of Power (SoP), fault diagnostics, and cell balancing
• Design and implement protection logic, thermal management, and charging strategies
• Model and simulate battery behavior using MATLAB/Simulink and PLECS
• Write and optimize real‑time embedded software in C/C++ for BMS microcontrollers
• Execute testing strategies including Model‑in‑the‑Loop (MIL), Software‑in‑the‑Loop (SIL), and Hardware‑in‑the‑Loop (HIL)
• Collaborate with battery, thermal, system integration, and software engineering teams to ensure seamless vehicle deployment
• Ensure systems align with industry standards including ISO 26262 and AUTOSAR

• Hands‑on experience in BMS algorithm development (e.g., SoC/SoH estimation, fault handling, thermal modeling)
• Strong programming skills in MATLAB, Simulink, Embedded C/C++, Python
• In‑depth knowledge of battery chemistries such as Li‑ion, LFP, NMC
• Proficient in control theory, including digital filters and Kalman filters (EKF/UKF)
• Familiarity with CAN protocols, UDS, and diagnostic tools

• Exposure to ISO 26262 functional safety processes
• Experience with machine learning for battery performance prediction
• Automotive development knowledge using ASPICE and V‑model lifecycle

• 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

If you are passionate about bringing innovation to the projects you work on and want to join a global company, then this is the place for you.
