Development Engineer

At Helio displays, we're crafting the fundamental materials that will shape the future of displays. 

Using the power of perovskites, this enabling material facilitates the creation of displays that are not only brighter and more vibrant but also operate with remarkably low power consumption.

Our team is dedicated to pioneering the future of colour. As we accelerate, we are looking for talented individuals to join us on the next phase of our journey. 


  • You will play a key role in the research, development and characterisation of our Perovskite material which will be used for novel MicroLED technology
  • Working closely with our senior development engineer you will design new solutions in order to test our materials  as we progress the technology and integration with microLED technology
  • Contribute to testing the optical performance of our materials 
  • You will work closely with cross-functional teams to optimise the performance of the material, troubleshoot issues and contribute to the advancement of the technology  
  • Develop software tools for data analysis and automation of tests 
  • Keep up to date with latest advancements of the technology and suggest new lab equipment in order to advance our technology
  • Optical simulation of our colour conversion films which  include simulation light propagation, extraction & filtering
