Senior Silicon Photonics Engineer (PIC Design)

About Rain Tree Photonics

At Rain Tree Photonics, we are building next-generation optical engines for co-packaged optics (CPO) and near-packaged optics (NPO) to break the bandwidth and power bottlenecks in AI infrastructure.

Our silicon photonic ICs power 200G/lane and beyond interconnects, enabling scalable, energy-efficient connectivity for AI data centers.

Role Overview

You will design high-speed silicon photonic integrated circuits operating at the limits of bandwidth and integration, and take them from concept → tapeout → silicon validation .

This role is suitable for strong PhD graduates through early-career engineers (0-5 years experience) who want to work on real, production-bound systems , not just simulations.

Roles & Responsibilities

• Design and optimize silicon photonic devices and circuits , including:
• High-speed ...
