Principal Process Development Engineer

Department: R&D

Employment Type: Full Time

Location: Plymouth

Description

Seeking a Principal Process Development Engineer with deep expertise in process development, strong analytical and problem solving skills, hands on experience with advanced fabrication and characterization techniques, and a proven ability to lead cross functional R&D initiatives.

Join a fast growing Process Development team pushing the boundaries of innovation in MicroLED and Optical Computing. Around 60% of your time will be spent in a state of the art cleanroom advancing process development, and the other 40% on planning, analysing data, and presenting insights to management.

Key Responsibilities
  • Lead the development and optimisation of fabrication processes for MicroLED and Optical Computing devices.
  • 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 MicroLED and Optical Compute 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
