Senior Motor Drives Engineer


Malmesbury, United Kingdom


Dyson offers a unique opportunity for a talented and experienced Senior Electronics Engineer focusing on Battery Management Systems & Cell Performance 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. That’s the Dyson way.


Applicants for this particular role must have significant experience in the specific areas of battery management and cell / pack performance characterisation.

The senior electronics role will involve:

  • The development of battery management systems and assessment of alternative battery management solutions and topologies depending on the product requirements.

  • Strong awareness and input to the mechanical design of the battery pack to ensure the best overall compromise is achieved between measurement accuracy, thermal management, pack volume and pack safety.

  • Ensuring battery management systems meet regulatory and company requirements for safety.

  • Evaluation/design of cell balancing strategies with the emphasis on safety, cost, volume and mass of the solution.

  • Ensuring designs can comply with relevant EMC/EMI standards and modifying design where needed to ensure compliance.

  • Thermal management design of electronic systems (assisted by specialist thermal engineers).

  • Use of simulation and PCB design software to create prototypes.

  • Strong lab skills to build and test prototypes with minimal supervision.


    As a senior employee, the successful applicant will be expected to:


  • Develop the concept, proving key technologies and demonstrating the system feasibility.

  • Prove the production intent solution and create suitable documentation prior to handover to the development teams.

  • Demonstrate designs are robust, cost effective and fit for purpose for a high volume manufacture environment, through detailed laboratory testing, simulation and analysis.

  • Assist in the personal development of junior team members.


Education and experience:

  • Minimum BEng/MEng degree in Electronic Engineering or other relevant discipline with a demonstrable level of industrial experience in a relevant industry.


    Minimum technical knowledge:


  • Design of electronics for complete battery management systems

    • Design of battery management systems, especially for Lithium-Ion technology.

    • Knowledge of thermal design for a broad range of applications– i.e. surface mount and through hole devices, heatsinking, insulating/mounting, airflow.

    • Good understanding of how to conduct high currents in cables, connectors and PCBs whilst minimising inductance.

    • Design techniques to meet EMC requirements.

    • Excellent knowledge of the specification, selection and testing of fuses.

  • Design tools:

    • Schematic capture using Mentor Graphics or other main stream tools.

    • Use of SPICE based simulation tools such as Simetrix

    • Design calculation tools such as Mathcad, Matlab, Excel

  • Design techniques:

    • Circuit simulation and design tolerance analysis

    • Good quality engineering process understanding and appreciation

    • Design for high volume manufacture

    • PCB layout – size/cost minimisation while achieving layouts for inherently good EMC compliance and thermal design

  • Control circuit design:

    • Excellent understanding of techniques for accurately monitoring mV signals in V of noise.

    • Excellent knowledge of non-ideal behaviour in analogue to digital converters, op-amps, comparators, voltage references etc. including ways to manage these non-ideal characteristics.

  • Cell characterisation:

    • Working with Cell electrochemists and Cell application engineers, actively collaborate in the specification and implementation of both cell and pack level electrical, thermal and mechanical characterisation.


      Desirable technical knowledge:


    • Robust design including FMEA techniques.

    • Battery charging using wireless power transfer.


    • Essential practical skills:

  • Ability to build, test and modify prototypes accurately, safely and with minimal supervision.

  • Excellent understanding of the dangers inherent in cells and batteries.


    Essential behavioural skills:


  • The ability to take a leadership position within a project with little direction.

  • Good analytical ability and attention to detail.

  • Ability to communicate appropriate, concise and accurate information in written and verbal format.

  • Ability to adapt or generate imaginative and innovative ideas, in line with core Dyson values.

  • To be able to multi-task and plan effectively when working with a variety of project teams in an often high-pressure, competitive environment in an organised manner.

  • Excellent team working skills.
