Our Opportunity

Work Location:  Kidlington, Oxfordshire 

Roster: Monday - Friday 
 

Role Purpose: 
The Senior Battery Algorithms Engineer will Support the development and validation of the Elysia Embedded product algorithms.

Develop high performance battery state estimation and control, and diagnostics and prognostics algorithms aimed at maximising the performance, safety and life of battery systems.

Key Responsibilities

•    Develop high-performance battery state estimation and control algorithms across multiple cell chemistries and operating conditions.
•    Design and improve advanced diagnostics and prognostics algorithms.
•    Formulate algorithm concepts from first principles, experimental insight, and data-driven analysis, translating theory into robust, real-time deployable solutions.
•    Lead simulation-based validation campaigns using representative drive cycles, ageing scenarios, and environmental conditions to assess algorithm accuracy, stability, and robustness.
•    Plan, execute, and interpret cell-level test data for algorithm validation activities.
•    Analyse cell, module, and pack-level datasets to evaluate algorithm performance and identify edge cases.
•    Investigate algorithm sensitivities, parameter dependencies, and failure modes to ensure robust behaviour across temperature, ageing, and usage variability.
•    Collaborate closely with cell modelling, validation, software and application teams to ensure strong alignment between cell models, algorithm implementation and deployment.
•    Produce clear technical documentation capturing algorithm design rationale, assumptions, validation results, performance metrics, and improvement recommendations.
•    Contribute to continuous improvement of algorithm validation methodologies and technical best practices, ensuring high engineering standards and compliance with internal quality frameworks.

Qualifications and Experience

Details of the experience needed to be successful in the role, the qualifications essential/desirable to be able to fulfil the role and any specific behavioural traits.

Essential:
•    Bachelor’s or master’s degree with a minimum 2:1 (or equivalent) in a relevant STEM subject. (e.g. Mathematics, Physics, Statistics, Computing, Mechanical Engineering, Electrical Engineering, etc.).
•    Experience in leading development of state estimation or control system algorithm (Kalman Filters, MPC, etc.)
•    Excellent communication skills and the ability to prioritize tasks and maintain a high-level view of project goals.
•    Strong problem-solving skills and the ability to think critically and analytically.
•    To have a ‘can do’ proactive attitude day in day out and proactively support and collaborate with others.
•    They will be able to take on new ideas, concepts, and ways of working to meet strict project deadlines.
•    Willingness to proactively build new relationships & connections across the business in support of team & company goals.

Beneficial:

•    Understanding of physics-based battery models (e.g. DFN, SPM etc.).
•    Experience in development of state estimation algorithm for battery applications (State of Charge, State of Health, State of Power,etc)
•    Expertise in model based development and data analysis in MATLAB/Simulink.
•    Experience with data driven methods (Gaussian process, Embedded Machine Learning)
•    Experience with cell modelling tools such as PyBaMM, COMSOL or similar.
•    Experience in electrical testing of battery cells, including development of test plans.
•    Experience in ASPICE processes.
•    Experience with embedded systems and hardware
•    Experience in electro-thermal modelling of battery systems
•    Experience with version control and CI/CD frameworks (e.g., Github, Gitlab, Azure DevOps).

This job description is not exhaustive, and the job holder will be required to carry out from time-to-time tasks in addition to the above that will be both reasonable and within their capabilities.
