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
