Delta Cosworth is an electrification specialist delivering electric and hybrid solutions. Our main business streams are Battery Systems, Power Generation and Vehicle Systems Integration.

Delta provides world class technical innovation, engineering and testing services to deliver energy efficient performance to our customers, meeting the challenges of the 21st century: Efficiency, Sustainability and Mobility.

As a business, we are constantly seeking innovative ways to lead technology development while striving to deliver the reliability that our customers expect.  Therefore, we are hiring innovative professionals to join our team here at Silverstone.

As a member of the Battery Management Systems Team, the Battery Modelling Engineer would be contributing to the successful development of Delta’s internal battery modelling tool software. With a primary focus on high-performance battery systems, the software developed will be for a range of battery vehicle applications (automotive, motorsport, marine, aerospace, and off-highway).

The responsibilities of the Battery Modelling Engineer will be to develop cell, module, and pack level models for generating offline predictions to support the systems team with proposal & design decisions, and online models for use on the BMS to improve the performance of the battery packs.

This role will suit a candidate that will work well in a team, able to communicate with other departments, and maintain strong links with academic institutions to keep up to speed with the latest research.


  • Battery modelling:
    • Cell modelling: predicting battery performance for pack design, providing information to feed Battery Management System (BMS) development
    • Experience with cell electrical & thermal modelling (finite element thermal models, cell ageing modelling from theoretical models and/or experimental data, Object-oriented multi domain modelling of singles cells for performance, heat generation, temperature distribution)
  • Module and pack modelling:
    • Scaling up of cell models from a lumped model into module or pack model
    • Modelling different cooling systems interfacing cells to inform design
  • Battery testing:
    • Supporting battery test planning to validate models developed
    • Parameter extraction (input data for BMS algorithms: Capacity and OCV curve extraction, ECMs, DCIR)
    • Data analysis (automated scripting, exploration, pattern spotting, reporting)


  • Knowledge of battery system architectures and battery management systems
  • Experience of using model-based development languages such as Matlab & Simulink
  • Knowledge of cell electrical & thermal modelling techniques
  • Knowledge of cell testing techniques
  • Ability to generate battery model plans, analyse data and report on performance
  • Proactive, self-motivated with a keen attention for detail
  • Willing to learn new skills & problem solve on exciting, technically challenging projects
  • Communication & team working skills


  • Degree qualified in a relevant engineering discipline
  • Familiar with laboratory equipment and test facilities
  • Familiar with measurement, calibration & testing conditions
  • Exposure to other coding languages (C, C++, C#, Python)
  • Familiar with good software practices, coding standards, version control/management, issue tracking, and testing
  • Ability to conduct literature research to keep up to date with latest developments
  • Familiar with creating reporting in Power BI (DAX) & database management (SQL)
  • Minimum 1 – 2 years in a previous full time engineering role


As well as the opportunity to become part of the Delta Cosworth family that will support you in developing your career, we offer a generous benefits package which includes:

  • 25 days holiday plus Bank Holidays
  • Workplace pension matched up to 6%
  • Free onsite parking
  • Private Medical Insurance (optional opt in after probation period)
