Job description

We’re seeking an experienced Principal Engineer – RF Integration Photonic Device to lead the RF design of high-speed modulators for our client’s cutting-edge silicon photonics platform.This is a chance to work on next-generation optical communication technology in a global R&D environment.Main Responsibilities of Principal Engineer – RF Integration Photonic Device

• Lead RF design for high-speed travelling-wave optical modulators.
• Model, simulate, and optimise RF circuits (travelling lines, baluns, biasing, termination).
• Collaborate with driver and processing teams to create tailored solutions.
• Develop and test new equalisation techniques to boost bandwidth and performance.
• Characterise high-speed devices and analyse experimental data.
• Support photonic component, subsystem, and circuit design.

Integrated optics & silicon photonics – RF line design & simulationPhotonic component modelling and validationKey Requirements Principal Engineer – RF Integration Photonic Device :Must-Have

• PhD in Photonics, Electrical Engineering, Physics (3+ years relevant experience) OR MSc in same fields (6+ years relevant experience).
• Proven experience in photonic component design (silicon photonics or III-V materials).
• Expertise in RF design for high-speed modulators (e.g., travelling-wave designs, impedance matching, termination circuits).
• Skilled with RF simulation tools (CST, HFSS, ADS, COMSOL).
• Experience in RF characterisation and testing of high-speed devices.
