Design Engineer - Optics


Product Design
Malmesbury - United Kingdom


The use of optical and light technologies is a rapidly growing area for Dyson, ranging from various photoreactors to integrated general illumination systems and indication, across all categories. It is essential that NPI categories have access to optical design resource to develop optical schemes and technologies quickly and effectively at the concept generation stage of the design. 
The role requires Design Engineer with a good background in general engineering ideally with knowledge of optics or physics. This engineer will be an integral part of the EC support team with responsibility for the design and development of visible wavelength optical schemes on several different projects. They will need capable of interacting and with different project teams and categories as well as providing support and solutions for multiple projects. They will need to be practical, with a hands on approach to designing, prototyping and evaluating solutions. Experience in general illumination and luminaire design would be beneficial, but tailored training will be available; priority is for experience using scientific techniques and understanding to optimise designs into feasible solutions.


  • Support the Advanced Optical Design Engineer in NPI EC team in the generation optical designs and solutions through the use of raytracing and optimisation software and CAD 
  • Construction and commissioning of prototypes and test rigs involving optics/light for evaluation and testing. 
  • Identification and analysis of new technologies or innovations in optics / illumination.
