Battery Pack Mechanical Engineers – Entry Level/Senior/Lead/Principal


Mechanical Engineering
Malmesbury - United Kingdom

About us

At Dyson we are encouraged to think differently, challenge convention and be unafraid to make mistakes. We are proud to be authentic, different and pioneers. We are driven by a desire to solve real problems and improve everyday lives with intuitive solutions that do more but use less. Family owned, we are not restricted by conventional thinking; we explore, discover and learn for ourselves. Never satisfied, we believe everything can always be made better.

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 Battery Packs powering innovative products in existing and new product categories. The team expertise encompasses design, mechanical & thermal design, and the engineers works closely with Energy Storage and Power Electronics and Product teams.

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

Due to a significant expansion in headcount, an exciting opportunity has arisen for a multiple Mechanical Engineers with a broad mechanical and thermal skill set to join the rapidly growing Battery Pack team within the Technical Research department. The team are pioneering methods of integrating Dyson's own state-of-the-art cell technology, as well as delivering improvements to packs with commercial cells. Prior experience of Battery Pack or Power System integration is highly desirable.

  • Stretch the boundaries of power and energy density in our Battery Packs, whilst ensuring safety, robustness and reliability.
  • Support the design of robust solutions and resolve technical challenges across multiple platforms and projects, whilst liaising with technical experts in Cell Design/Power Electronics/Product Design teams.
  • Characterise and drive down selection of solutions via the most effective means possible, starting with first principle calculations and working through to detailed simulation or test.
  • Ability to identify technical risk, then reduce by owning and delivering FMEA and DVP.
  • Create and drive development of technical requirements, including compliance with relevant International Standards
  • Create new, and improve upon existing, best practices and processes within the team
  • Develop innovative and novel concepts with high value IP while considering freedom to operate
  • Develop 3D CAD and engineering drawings - to BS8888 - for battery components and assemblies, along with test rigs and assembly fixtures.
  • Lead/work with other specialist Mechanical and Thermal engineers, defining problem statements and understanding the verification tools used, including limitations. [level dependent]
  • Be a source of engineering expertise to advise on mechanical design, development, material, manufacturing limitations, prototype build and test issues. [level dependent]
  • Lead projects through Dyson’s technology readiness process. [level dependent]
  • Review and approve work completed by others, and mentor others within the wider team [level dependent]
