Principal Engineer


Motors and Power Systems
Malmesbury - United Kingdom


Dyson offers a unique opportunity for a talented and experienced Principle Engineer in the Technical Research Team, within Dyson’s Research, Design and Development (RDD) department; based in Malmesbury, Wiltshire, U.K.


  • Mentoring staff within the New Concepts team, within the Power and Electronic Systems Research team, covering multiple software/hardware elements of several projects.
  • Working with the different sub teams within Technical Research, as well as NPI, other research groups and development teams to gain an in depth product understanding, while using your expert knowledge of the latest technologies to create innovative systems and solutions.
  • Ensuring the team develops shortlisted ideas/concepts and demonstrates designs are robust and viable for use in product through more detailed laboratory testing.
  • Ensuring the team generates suitable test specifications to ensure product reliability, safety and robustness. This includes the development of test environments including simulation, emulation and hardware/test equipment interactions.
  • Hardware design review activities (schematic reviews and pre/post PCB layout reviews).
  • Working with other disciplines to solve complex system level problems and find software/hardware solutions.
  • Where applicable, ensuring electronic requirements and architecture details are documented by the team.
  • Assisting in pulling together review packs which typically include concept specifications, requirements and specification documentation, risk registers, FMEAs and design guides when needed
  • Managing technical risks in a project through FMEAs, reporting, and actively driving down risk with targeted tasks where applicable.
Identify emerging IP and ensure inventions are submitted to the IP team.
