Principal Engineer - Photolithography
Job Summary
We are seeking a highly skilled and innovative Principal Engineer specialising in photolithography processes to support advanced photonics R&D and manufacturing. You will be responsible for optimizing existing photolithography processes for R&D and production wafers, while also developing and leading new process technologies to meet the requirements of future photonic devices. Working closely with facilities, equipment, process integration and device engineering teams, you will help drive processes from development through to manufacturing and support technology transfer into high-volume production.
Key Responsibilities
- Lead the development and optimization of advanced photolithography processes for InP photonics applications.
- Support photolithography equipment installation, calibration, process qualification and ongoing performance optimization.
- Work closely with device design teams to translate photonic designs into high-precision, manufacturable structures.
- Establish robust process control and characterization methodologies to improve yield, consistency and device reliability.
- Identify, investigate and resolve lithographic patterning issues and process deviations.
- Research and implement emerging photolithography techniques, resist materials and process technologies.
- Provide technical leadership and guidance to engineering teams, developing expertise in advanced lithography.
- Collaborate across disciplines including epitaxy, etching, process integration and device testing to ensure robust fabrication workflows.
- Lead R&D projects, coordinating technical activities, milestones and deliverables.
- Support process transfer and scale-up into high-volume manufacturing.
