Principle Duties and Essential Functions
•
Support the architecture, design, and validation of high‑speed RFICs (Laser Drivers, TIAs, analog front‑ends) for optical transceivers and optical engines
•
Define RFIC specifications and roadmaps aligned with coherent and direct‑detect optical platforms (100G, 800G ZR / ZR+, 1.6T ZR / ZR+)
•
Own technology selection and trade‑offs across SiGe BiCMOS, RF CMOS, and advanced foundry processes
•
Drive RFIC development through the full lifecycle: concept → silicon → bring‑up → DVT → PVT → MP
