About us

Dyson offers a unique opportunity for a talented and experienced Lead Power Electronics Engineer in the Technical 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 from the competition and be ahead of the times.

You will be be part of the team designing the next generation of power electronic systems for our products. The power electronics team in Technical Research is responsible for a number of disciplines, including:

  • Motor inverter hardware for motor systems that can operate in excess of 100,000rpm

  • Power supply design - DC-DC and AC-DC designs

  • Battery management systems - design of Lithium-Ion battery management systems for a variety of products and cell pack structures, as well as development of new battery management system for emerging cell technologies

  • Charger design

  • Heater control systems and protection

About the role

Key responsibilities

  • The design of motor inverters and control for brushless DC, servo and stepper motors and the design of heater control hardware and associated protection systems.
