The Role
Develop and optimize semiconductor fabrication processes for MicroLED and optical interconnect products. Responsibilities include defining process architecture and modules, improving pixel performance, planning experiments, analyzing data, conducting risk assessments and design reviews, specifying new tooling and process recipes, and presenting recommendations to management. The role is approximately 60% hands-on cleanroom work and 40% experimental planning, analysis, and cross-functional communication.
Summary Generated by Built In
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.
Benefits
