Job description

Position Overview

We are seeking a Principal Engineer (Transmit) to lead the development and productization of optical engine (transmitter) used in high-speed optical transceivers. This role focuses on optical engine integration, characterization, and manufacturing readiness rather than device design. The successful candidate will work closely with photonic device designers to integrate EML transmitters, high-speed modulators, and waveguide photonic components into robust optical engine products suitable for high-volume production.

Key Responsibilities

• Lead Transmit Productization: Drive the end-to-end development of optical engine transmit modules, managing the transition from prototype validation to high-volume manufacturing.
• Translate Specifications: Convert device-level capabilities into comprehensive optical engine performance specs and rigorous validation plans.
• Component Characterization: Develop and execute characterization plans for EMLs, high-speed modulators, and photonic waveguide structures.
• Evaluate Key Metrics: Analyze critical transmitter parameters, including optical output power, extinction ratio, modulation bandwidth, and temperature dependence.
• System Integration: Collaborate with design teams to integrate laser sources and modulators into complete, high-performance optical engines.
• Manufacturing Strategy: Establish engineering and production test flows specifically tailored for transmit module screening and validation.
• Yield & Reliability Analysis: Utilize production data to pinpoint performance variations, yield detractors, and potential reliability risks.
• Automated Data Workflows: Implement automated data analysis and reporting tools to identify root causes of transmitter performance limitations.
• Cross-Functional Technical Support: Partner with packaging and sales teams to provide technical insights for product documentation and market-facing specifications.

Requirements

• Bachelor’s degree in Electrical Engineering, Photonics, Physics, or a related field.
• Master’s or PhD in photonics and optoelectronics preferred.
• 8–12+ years of experience in photonics, optical communications, or semiconductor optoelectronic product development.
• Experience with optical transmitter or optical engine products 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.
