Thermovoltaic energy storage
About the job
Company Overview
Aed Energy Ltd is a pioneering energy storage technology company at the forefront of developing long-duration energy storage systems with dual heat and power delivery. Our systems convert electricity into high-temperature heat and regenerate it using thermophotovoltaics. We are looking for a capable and hands-on Senior Thermal Engineer to join our growing team and support the design and testing of our next-generation MWh-scale storage systems.
Job Overview
As Senior Thermal Engineer at Aed Energy, you will take ownership of high-temperature system modelling, mechanical analysis, and validation. You will be responsible for detailed CFD and thermal simulations, component-level design, material selection, and lab-based testing of assemblies operating up to 1000°C. You will collaborate across mechanical, electrical, and systems engineering to deliver robust, manufacturable, and scalable thermal designs.
This role is ideal for an engineer with strong simulation and experimental skills, who is excited to build real hardware and contribute directly to product performance in a fast-paced startup environment.
Requirements
Key Responsibilities
