Position Overview

We are seeking a Principal Engineer (Receiver) to lead the development and productization of optical engine (receiver) for high-speed optical transceivers.

This role focuses on receiver optical engine integration, characterization, and manufacturing readiness. The successful candidate will work closely with photonic device and circuit designers to integrate photodiodes/APDs, passive waveguide photonic components, and receiver electronics into robust optical engine products suitable for high-volume manufacturing.

Key Responsibilities

Lead Productization: Drive optical engine receiver modules from prototype validation through high-volume manufacturing ramp.
Define Specifications: Establish receiver OE specifications, validation methodologies, and performance targets based on device-level capabilities.
Component Characterization: Develop and execute advanced characterization for PDs, APDs, and TIAs, focusing on responsivity, bandwidth, and sensitivity.
Passive Photonics Validation: Validate passive waveguide structures, including loss analysis, fiber-to-waveguide coupling, and mux/demux performance.
Yield & Reliability: Analyze production data to identify yield detractors and reliability risks, driving continuous improvements in manufacturability.
Test Automation: Design automated test flows and data analysis workflows for deep-dive root cause analysis of performance limitations.
Cross-Functional Synergy: Collaborate with design, packaging, and sales teams to align receiver capabilities with market needs and technical documentation.
Technical Mentorship: Provide strategic leadership and mentor junior engineers to advance the company's photonic integration roadmap.

Requirements

Bachelor's degree in Electrical Engineering, Photonics, Physics, or a related field.
Master's or PhD preferred, particularly in photonics or optoelectronics.
8–12+ years of experience in photonics, optoelectronics, or optical communication product development.
Experience developing receiver subsystems or optical engines used in optical transceivers.
Proficiency in data collection and analysis using Excel is required; experience with JMP, Python, C/C++, MATLAB, LabVIEW, R, or similar tools is preferred.
Experience with mask layout tools (e.g., KLayout, LayoutEditor) and simulation tools (e.g., Lumerical FDTD, RSoft, ZEMAX, SolidWorks) is an advantage.
Strong analytical, problem-solving, and strategic thinking abilities with excellent communication and cross-functional collaboration skills.
