Senior Photonics / Optical Switching Engineer
We are looking for an experienced Photonics Engineer to develop next-generation optical switching technology for high-speed communication applications.
You will work across photonic integrated circuit (PIC) design, optical switching architectures and high-speed electronics, helping translate market requirements into technical solutions and taking new concepts from design through prototyping and demonstration.
Key Responsibilities
Market & Application Understanding
- Understand market requirements for optical switching and the architectures needed to address them.
- Work with business development to translate application needs into technical requirements.
- Contribute to the ongoing development and evolution of the photonics platform.
Architecture & Circuit Design
- Develop innovative optical circuit switches and switching architectures.
- Design supporting control circuits to address high-speed switching challenges.
- Analyse switching performance, including speed, insertion loss, crosstalk and scalability.
- Develop control-loop strategies, including bias control and calibration, to ensure fast and stable switching.
Prototyping & Demonstration
- Design PIC optical circuits for switching demonstrators.
- Specify high-speed control electronics required to drive and stabilise optical switches.
- Build prototypes, test performance and present results to internal and external stakeholders.
- Document designs, results and performance trends to support further platform development.
Requirements
- Master's degree or PhD in Photonics, Electrical Engineering, Physics or a related discipline.
- Minimum 3 years of relevant experience in photonics or high-speed integrated systems.
- Experience with silicon photonics platforms, such as SOI or SiN.
- Practical experience in PIC design and integrated photonic circuit layout.
