Senior Thermal Design Engineer – Birmingham
We are supporting a leading-edge technology business in the recruitment of a Senior Thermal Design Engineer for their growing UK R&D centre. This role offers the chance to contribute to the development of high-performance systems used in electrification, sustainable energy, and industrial mobility applications.
This is a key opportunity for an experienced engineer with strong thermal design skills, simulation capabilities, and an interest in advanced materials and cooling technologies used in power electronics or similar high-reliability systems.
Overview for the Senior Thermal Design Engineer job:
- Lead the thermal design and optimisation of complex power modules and high-density power systems
- Design and model advanced heat sinks and cooling structures to meet thermal and mechanical requirements
- Conduct simulation work (thermal, electro-thermal, CFD) to verify performance and guide design iteration
- Collaborate with electrical, mechanical, and systems engineers to ensure cross-functional integration
- Analyse materials, packaging technologies, and bonding techniques for thermal reliability
- Support prototype development, thermal testing, and reliability assessments
- Work closely with suppliers on thermal components, materials, and assembly feasibility
- Create clear documentation, design reports, and technical communication for internal and external stakeholders
Key Requirements for the Senior Thermal Design Engineer job:
- Degree in Mechanical, Thermal, or a related engineering discipline (MSc/PhD advantageous)
- 3–5 years’ experience in thermal or structural design for power systems or high-performance electronic assemblies
- Strong knowledge of heat transfer, thermal interface materials, and cooling strategies
- Experience with CAD (Solid Edge/SolidWorks) and simulation tools such as ANSYS or COMSOL
- Understanding of thermal considerations in system packaging, materials science, and reliability
- Background in energy systems, EVs, renewables, or electronics packaging is desirable
- Strong analytical skills, cross-functional collaboration, and technical reporting abilities
This is a great opportunity to work on pioneering projects with global impact in energy and mobility sectors. My client can offer a competitive salary and benefits package plus also work on a hybrid model.
