About us
Plessey has a long history of innovation.
Founded in 1956, we have evolved from one of Europe’s earliest semiconductor pioneers into the world’s most advanced microLED specialist. Over the decades, Plessey has built a first class, fully integrated platform designing, manufacturing, and engineering next- display technologies entirely in-house. This end to end capability, combined with our strong IP portfolio, uniquely positions us to lead the scaling of MicroLEDs from lab innovation to high-volume production.
Our future is even brighter.
We believe microLEDs will define the next era of technology—powering ultra-efficient AR/VR displays, driving optical processors that make AI faster and more sustainable, and enabling devices yet to be imagined. With our unique expertise and talented team, we are positioned to lead this transformation.
It’s an exciting time to join us: Plessey has recently been acquired by
Haylo Labs , accelerating our growth and opening new opportunities.

About the Role
As we begin this new chapter, we are expanding our in-house capabilities in MOCVD and building a dedicated team to bring our vision to life. This role offers the opportunity to work in a small, highly skilled team, driving the development of state-of-the-art technology platforms. You will have the opportunity to make a big impact.
Key Responsibilities
Support the development of cutting-edge technology platforms for the design and manufacture of high-efficiency MicroLED products
Play a key role within the Phosphide and Nitride Epitaxy Team, contributing directly to the company’s R&D strategy
Support delivery of the epitaxial roadmap, aligning both short- and long-term product requirements with wider business goals
Lead testing and analysis of new processes, including characterization, process control, and quality assurance
Collaborate closely with engineering teams including Process Engineering, Equipment Owners, Characterisation & Test, and Shift Engineers in order to deliver successful outcomes
Actively identify and implement opportunities for innovation and continuous improvement
Consistently deliver high-quality results while balancing development and production demands
Experience & Attributes
BSc, MSc, or PhD in Materials Science, Physics, or related field
Hands-on experience with MOCVD growth
Strong background in R&D and process engineering within related high-technology fields
Experience with within gallium nitride (GaN) or gallium phosphide (GaP)
Hands-on experience with MOCVD systems (Veeco, AIXTRON, etc.)
Creative thinking to optimize processes under complex constraints
Ability to stay motivated through setbacks or inconclusive results
Advantage
Experience within Photonics applications and/or MicroLED
Awareness of the technology landscape and competitive environment within the sector
Proficiency in optical, thermal, and/or electrical simulations
Exposure to analogue and power technologies
Familiarity with gated product development processes
Knowledge of failure analysis, defect classification, and quality tools
Knowledge of device processing
