• Perform structural, electrical and optical characterisation of fabricated devices
• Maintain accurate process documentation and experimental records
• Track and report project progress clearly, identify risks early, and develop practical solutions to technical problems
• Support process development by fabricating test structures and experimental device designs
• Contribute to process troubleshooting, failure analysis and defect reduction
• Work closely with wider engineering teams including process engineers to support optimisation of transfer yield and device integration
• Contribute to the development of robust fabrication workflows, standard operating procedures and process control methods
• Work safely and effectively within cleanroom, laboratory and workshop environments, following relevant procedures and documentation requirements

• PhD or comparable experience in a related engineering or science discipline
• Strong experience with photolithography, dry and wet etching, metallisation, SEM and structural characterisation
• Strong communication skills, with an open and collaborative approach to reporting results, discussing problems and working across teams
• Be strongly motivated and capable to apply your existing skills and develop new ones to deliver progress towards Pixel-Flo’s technical and commercial ambitions
• Dependable, diligent and flexible, with the ability to deliver high-quality technical work in a dynamic start-up environment where priorities can evolve quickly

• Experience with III-nitride materials and LED device fabrication
• Experience developing and optimising device fabrication processes
• Experience with direct write laser lithography
• Background in LED or optoelectronic devices
• Understanding of semiconductor device physics
• Electrical and optical device testing
• Experience with photomask design tools (e.g. KLayout)
