Characterisation Engineer


Energy storage
Oxford, United Kingdom

About us

Dyson is a global technology enterprise. We solve the problems others choose to ignore, with surprising new inventions that defy convention and simply work better. We’re growing fast andour ambition is huge – more categories, more locations and more people.
We push the boundaries of what others have defined as possible. Our approach starts with an engineering mindset and different thinking. Then we continuously refine our ideas – unwilling to compromise and driven by an obsession for finding a better way. 
Dyson’s interest in researching and developing energy storage technologies started more than a decade ago, when it became apparent that the full potential of our DDM motors were starting to be held back by commercially available batteries. Fast-forward to 2021, and we now have over 100 scientists and engineers working on battery R&D across our labs in the UK, US and Singapore. 
With multiple generations of Dyson battery technologies ranging from early research through the industrialisation phase, Dyson are recruiting a wide range of roles across their UK and Singapore labs to accelerate progress. These roles include materials scientists, electrochemists, cell design engineers, cell test technicians, cell assembly technicians, mechanical design engineers, manufacturing process development engineers and manufacturing technologists. We are recruiting at all levels of seniority up to senior technical leadership roles. 

About the role

Dyson requires a skilled and highly motivated Characterisation Engineer to help it achieve its current and long term battery ambitions and support its RDD lab activities. The person will be expected to spend the majority of their time in a research laboratory supporting the characterisation on new materials for Li ion batteries. The role will involve the investigation of the physical chemical properties of new materials. The ideal candidate is also expected to contribute to new ideas and support more broadly the research activities ongoing in the group.
Reporting to a Lead Engineer, you will join a growing team of chemists, physicists and engineers in Dyson’s Strategy &  Research Group. Your focus will be to understand and investigate the principles which govern the operation of next generation battery systems. You will: 
  • Have the ability to understand what contributes to and effects the energy density of lithium ion batteries.  
  • Maintaining and operating a raft of characterisation equipment 
  • Working closely with Materials Engineers to understand materials composition, structure and morphology. 
  • Problem solving with colleagues to understand synthetic problems.  
  • Problem solving with colleagues to diagnose cell failures. 
  • Develop new analytical approaches to study lithium ion batteries 
  • Establish measurement SOPs for a Characterisation Technician. 
  • Apply your knowledge to understand how cathode materials operate. 
  • Characterise the behaviour of these materials in cells. 
  • Interpret these results to generate models of understanding. 
  • Provide suggestions and guidance of how to find materials with related performance. 
  • Generate innovative idea with strong & high value IP. 
  • Work closely with other researches to ensure that the product performance, reliability and cost expectations are met, 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. 
  • Create plans and manage your own time using planning tools such as Microsoft Project and make sure this is integrated into the overall project plan. 
  • Write risk assessments and COSHH 
  • Work within an energetic research environment focused on innovation 
  • Be trained and developed to fully understand the R and D process for Li ion batteries
