Principal Engineer - Photonics / Sensors


Science and Research
United Kingdom - Malmesbury Office

About us

Dyson offers a unique opportunity for a talented Principal Electronics Engineer specialising in Sensors Systems within the Technical Research team.  Candidates with experience in gas, particulate, multispectral or hyperspectral sensing are encouraged to apply

The team is expanding this year and works across several product categories and is involved a range of technologies including embedded electronics, sensors and software.  We work very closely with the New Product Innovation (NPI) teams and deliver technologies into new products during the research phase.  A successful candidate will be working to generate new ideas and technologies to enable specific product features, as well as researching into future technologies. 

Some of the technology areas the team covers includes vision systems, particulate and gas sensing, microcontroller selection and software for the above, including control algorithm implementation.

About the Role

We work alongside the mechanical, thermal aero/acoustic teams in Technical Research and optical design engineers to help find the best technologies and integration approaches.  In this role the work will involve shorter term projects targeting specific products, alongside longer term research projects to bring emerging technologies into future products is part of the role. 

  • Work 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 and solve complex system level problems.

  • Demonstrate designs are robust and viable for use in product through laboratory testing and driving the team to develop simulations to optimise designs.

  • Ensure 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 (e.g. schematic reviews and pre/post PCB layout reviews).

  • Ensure requirements and architecture details are documented by the team.

  • Manage technical risks in a project through FMEAs.

  • Assist in producing review packs which typically include concept specifications, requirements and specification documentation, risk registers, FMEAs and design guides when needed.

  • Research into new and emerging technologies through visiting conferences, trade shows, meeting suppliers, reading papers and patents.

  • Identify emerging IP and ensure inventions are submitted to the IP team.

  • Develop relevant technology roadmaps and slide packs and presenting to the leadership team.

  • Help to manage laboratories and assist with risk assessments.

  • Mentor staff within research team to ensure team philosophies and working practices are applied to a project.

About you
