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

Technical owner for test strategy, infrastructure, and production readiness across product generations at Rain Tree Photonics.

Roles & Responsibilities

Test Architecture & Strategy
Define end-to-end test architecture from wafer-level to module/system-level validation.

Own design verification strategy, coverage, and correlation across simulation → wafer → system.

Technical Leadership
Lead and mentor test engineers; establish best practices for measurement accuracy, repeatability, and throughput.

Drive alignment across design, packaging, and manufacturing teams.

Advanced Characterization
Own complex high-speed electro-optic characterization (112G/224G PAM4 and beyond).

Debug cross-domain issues spanning RF, photonics, packaging, and signal integrity.

Production & Yield Ownership
Define die sort strategies, test limits, and guard-bands.

Lead yield analysis, excursion handling, and root-cause investigations.

Test Platform & Automation
Architect scalable automated test platforms for wafer and module test using LabVIEW, Python, and industry-standard instrument interfaces (e.g., GPIB, VISA).

Establish data pipelines for high-volume analytics and yield learning.

R&D & Roadmap Influence
Influence product architecture with testability and manufacturability considerations.

Evaluate and introduce new test methodologies and equipment.

Requirements

Education
Bachelor’s degree or higher in EE, Physics, or related field.
Experience
Typically 8–12+ years in silicon photonics, optical transceivers, or high-speed test.
Core Strengths
