Job Description

Senior Process Development Engineer

Department: R&D

Employment Type: Full Time

Location: Plymouth



Description


Join a fast-growing Process Development team at the forefront of MicroLED and Optical Interconnect innovation — technology that's shaping the next generation of displays and AI infrastructure.

You'll spend around 60% of your time hands-on in our state-of-the-art cleanroom, driving process development that goes straight into product. The other 40% is where you shape what happens next — planning experiments, analysing data, and presenting insights that influence decisions at management level.




Key Responsibilities

  • You will work on all stages of process development, defining process architecture, developing process modules, working with process development tool owners to develop and optimise pixel performance.
  • Constantly seek out and implement opportunities for innovation and improvement in the products and processes.
  • Participate in risk assessments and design reviews.
  • Identify the requirements for new tooling to support the development roadmap, including defining process recipe specifications and aligning with the process tool owner.
  • Leverage your R&D and process development experience to drive progress within a high-performing, results-oriented team.



Skills, Knowledge and Expertise


  • A PhD in Physics, Electrical/Electronic Engineering, Materials Science, or a related discipline focused on III–V semiconductor devices, or a bachelor’s degree with at least three years of relevant industry experience.
  • Hands on experience of developing and optimising InP or GaAs semiconductor device fabrication processes in a clean room environment.
  • Knowledge of semiconductor device physics.
  • Broad experience in semiconductor process techniques, including but not limited to lithography (stepper and mask aligner), etch (RIE, ICP and wet etch), CVD, PVD, Evaporation, ALD, IBD.
  • Design of Experiments and statistical analysis techniques.
  • Working knowledge of CAM systems and SPC.
  • Ability to communicate clearly, design decisions to cross-functional teams.
  • Experience of risk analysis and design review processes.
  • Experience with JMP or Python for data analysis would be an advantage.
