BMS Controls Engineer

BMS Controls Engineer / £50K - £75K DOE / Oxford / Onsite

We're partnered with a leading energy-systems division to recruit a BMS Controls Engineer. This is a hands-on engineering role focused on model-based design and embedded control algorithm development for battery energy storage and related stationary/power applications.

The Role
You'll develop and deploy embedded control algorithms for Battery Management Systems (BMS) used across energy storage and battery-powered systems. This sits at the intersection of control systems, embedded software and battery technology - ideal for engineers who enjoy end-to-end delivery from models to deployed code.

Key Responsibilities

• Develop control models for embedded targets: SoC/SoH/SoP/SoE estimation, thermal management, cell balancing, voltage/current limits, protection & diagnostics
• Design, simulate and validate models using MATLAB/Simulink & Stateflow
• Generate production embedded C code via Simulink Coder / Embedded Coder and deploy to microcontrollers (Infineon XMC, TI C2000, STM32, NXP)
• Support MIL, SIL and HIL validation workflows
• Integrate control logic with system, hardware and firmware teams
• Ensure requirements traceability (ISO 26262 / ASPICE experience beneficial)
• Debug, analyse and optimise real-time control performance
• Maintain model/version control using Git or similar tools

Requirements

• B.Sc. or higher in Electrical Engineering, Mechatronics, Control Systems or similar
• 5+ years' experience with MATLAB/Simulink for control development
• Hands-on experience with Simulink auto-code generation (Embedded Coder / Simulink Coder)
• Strong understanding of battery systems and state estimation techniques
• HIL experience (dSPACE, Typhoon HIL, or equivalent)
• Working knowledge of CAN and Vector tooling (CANalyzer, CANape, CANoe)
• Solid control theory, signal processing and embedded systems background
• Comfortable in a fast-paced product development environment
• Strong communication, problem solving and organisational skills

Desirable

• UDS diagnostics & battery communication protocols
• Safety-critical software exposure (ISO 26262, IEC 61508)
• Scripting for test automation (Python, MATLAB)
• Familiarity with Git, JIRA, Jenkins or DevOps tooling
• Basic C/C++ or embedded firmware experience
