Thermal Engineer


Malmesbury, United Kingdom


Thermal Engineer in the Motors, Power and Electronic Systems Research Team, within Dyson’s Research, Design and Development (RDD) department; based in Malmesbury, Wiltshire, U.K. 

Dyson Overview

Things move quickly at Dyson. In twenty years, what began with one man and one idea has grown into a global technology company, with 6,000 people and a presence in over 70 countries. From Malmesbury to Malaysia to the US to Australasia and many countries in between, we’ve sold over 80 million machines.

And it’s just the start. From 2016 our Malmesbury HQ is doubling its footprint. The US, our biggest market, is doubling their sales scope. And new frontiers are opening up across South East Asia and beyond. More people, more ideas and more space for more invention. The next four years will be our biggest and busiest yet.

Market Overview

Home to our global Research, Design and Development centre and all of our Commercial functions, Dyson HQ is tucked away in countryside famous for the railway tunnels and bridges of Isambard Brunel, who revolutionised modern engineering. Our secluded location helps us to protect our ideas and stay independent-minded. Yet nearby are the fashionable cities of Bristol and Bath (where a young James Dyson invented cyclone technology). The building is the heartbeat of Dyson. Over 1,500 people, including James himself, spend their days strategizing, inventing technology and telling the Dyson story to the world. From 2016, our HQ will begin doubling its footprint with an ambitious new expansion.

Function Overview

Sometimes, making a technological leap forward means going back to the beginning. Since 1999, we’ve spent £150m building a motor from scratch – small, light and efficient, yet extremely powerful. Our motors are what enable our technology to be different – it’s why they’re protected by 20 to 30 patents. But the next generation demands new directions. Energy storage, robotics, nanotechnology and space-age materials. So our multi-disciplinary team, led by some of the world’s best power electronics engineers, knows that only the most pioneering thinking will do.
