• 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

Knowledge / Experience

• 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

Preferred

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

Benefits

• Pension Scheme – we match employee contribution up to 5% of salary
• 25 Days Holiday
• Private Health Care
• Tata Jaguar Land Rover Privilege Scheme – up to 20% off new JLR vehicles
• Group Income Protection
• Health Assured
• Employee Assistance Program
• Group Life Assurance
• Health Shield

Private Health Cash Plan

In return for bringing your expertise to our business we offer a competitive salary along with excellent benefits including the items above.
