About the Job

Requirements

The candidate must be eligible for a placement year.
The candidate must be studying for a degree in Mechanical, thermal, or electrical engineering.
The candidate should have an interest in thermal management, modelling, and lithium-ion batteries.
The candidate should have good team-player and knowledge-transfer skills.
The candidate should demonstrate strong work ethic, ownership, responsibility, organizational skills, and time-management skills.
The candidate must be able to travel or relocate to Milton Keynes at their own expense to attend on-site part of the week.

Responsibilities

Develop an understanding of lithium-ion cell behavior and characterize dynamic responses under various conditions.
Explore factors influencing lithium-ion cell performance and the role of thermal management in safety and efficiency.
Gain hands-on experience using Ansys Fluent, FloEFD, GT-Suite, and MATLAB/Simulink to model battery-pack behavior.
Learn the Virtual Product Integration process and understand how simulation informs design decisions across development phases.
Collaborate with cross-functional technical experts and senior engineers to provide input and negotiate design solutions.
Document technical findings and best practices, present results in technical forums, and collaborate with the team to explore challenges and opportunities of lithium-ion technology in commercial-vehicle electrification.

We are looking for an enthusiastic Thermal Modelling Engineer student to join our team specializing in Li-ion battery packs for our simulation-based product development (SBPD) in Milton Keynes.
During your placement with us, you will learn how a major global organization operates, gaining the tools and exposure you will need to become an expert in the industry.
