Associate Principal Design Engineer




Dyson offers a unique opportunity for a talented and experienced Associate Principal Design 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.

At Dyson we are encouraged to think differently, challenge convention and be unafraid to make mistakes. We’re creative, collaborative, practical and enthusiastic, but most of all we’re hugely passionate about what we do. We are looking for individuals who wish to invent, design and develop leading products for the global market. By working in our world class Research Design and Development department, these individuals have the opportunity to work alongside other leading technical specialists and highly motivated creative people, to create products which fulfil our ambition of being truly different and better than our competitors. Dyson products strive to be at the leading edge of technology. Through unique strategic partnerships with global top universities and leading businesses, we gain foresight of up and coming technologies.

The technical research team aims to exploit this knowledge to design state-of-the-art products allowing us to differentiate our products from the competition and be ahead of the times. Dyson is expanding into several new and exciting product categories and is positioning itself as a technology company, confirmed by the release of the 360 Eye robotic vacuum cleaner and recent investments in Sakti3 solid state battery technology. Successful applicants for this role will be part of the team driving these products and others forward.

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

Motors & Power systems 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. That’s the Dyson way.


Reporting to Mechanical Manager, you will join a growing team of multi-disciplined engineers in Dyson’s Technical Research Group focussing on the next generation of advanced / high performance electric motors for new and existing categories demonstrating new core technology and a complete system design approach.
