About us

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 (RDD) centre, these individuals have the opportunity to work alongside other leading technical specialists and highly motivated creative people, to develop products which fulfil our ambition of being truly different and better than our competitors. Dyson monitors the market to ensure competitive salaries and pension contributions. Beyond that, you’ll also enjoy a profit-related bonus, generous leave and life insurance. However, financial benefits are only the start of a Dyson career. Rapid professional growth, leadership development and new opportunities abound.

Part of Dyson’s Strategy & Research Group, the Motors and Power Systems (M&PS) Research Team is responsible for the research, design and prototyping of the next generation of Dyson Digital Motors powering innovative products in existing and new product categories. The multidisciplinary technical expertise of the team encompasses design, mechanical, thermal, aerodynamic, acoustic, electromagnetic and motor control engineering.

The work often involves design-cycles of 1-2 years targeting specific products, alongside short-term research and scoping studies. Technologies transfer to the downstream development teams once they reach suitable maturity.

About the role

An exciting opportunity has arisen for an Associate Principal Motor Drives Engineer to join the highly successful Motors and Power Systems Research Team. Reporting to the Motor Drives Team Manager, the successful applicant will be working on the electromagnetic and/or motor control design of the next generation of advanced, high performance Dyson Digital Motors (DDMs) for low cost / high volume domestic / commercial applications;

Understanding and knowledge on both electromagnetic theory of electrical machines and motor control theory (including dynamic system simulation) are required with expertise in at least one of the two fields.


  • Steer the design process of multiple, project specific single- and multi-phase electromagnetic motors and/or motor control solutions to meet requirements
  • Act as subject matter expert in the field of electromagnetic design and/or motor control and dynamic system simulation, disseminating knowledge, guiding and mentor engineers in methodology, best practice and standards
  • Understand the overall product concept and contribute significantly to the design of the product through the use of expert knowledge of the latest technologies and methods in the industry
  • Design and develop novel high performance, single- and multi-phase electric motor topologies and construction methods and/or motor control solutions that meet target specifications such as cost, size, weight and efficiency
  • Use of 2D/3D static and transient electromagnetic Finite Element Analysis (FEA) to model detailed aspects of brushless motor designs
  • OR
  • Create, develop and use dynamic power system simulation tools in MATLAB/Simulink environment to:
  • Accurately model motor and drive performance
  • Develop motor controls and control strategies to meet the target performance
  • Optimise the motor and system design to meet product specific requirements, i.e. lowest cost, size and most efficient solution
  • Test & verify new motor drive designs
  • Proactively identify technical risks and opportunities within projects and influence engineering teams in their resolution, taking the lead when required in the design and testing of the engineering solution
  • Generate innovative and novel solutions with strong / high value IP for Dyson products while considering freedom to operate
  • Collaborate effectively with other Dyson motor drives, electronics, software, mechanical, thermal and aero-acoustics engineers from Malmesbury and Newcastle to ensure that the product performance, reliability and cost expectations are met, all within the planned timeline of the project
  • Communicate clearly and effectively the results and project status to a broad spectrum of associated project members and senior management
  • Actively feed into strategic discussions about research direction and planning
  • Have the ability to assess and handle supplier relationships with technical and commercial negotiations, maintaining confidence in BOM and assembly costs throughout a project
  • Create and manage your own time and the time of others in the team using planning tools such as Microsoft Project and make sure this is integrated to the overall project plan and managed by the Project Manager regularly and efficiently
  • Be a source of electromagnetic and/or motor control engineering expertise to resolve design, development, material, manufacturing, verification and testing issues
  • Develop and mentor others within the wider team
  • Challenge and develop best practice and process improvements within the wider team
