Fiber Optic Design Engineer - 224G PAM4 Optical Modules

Position Overview

This role focuses on precision optical design and assembly, including lens positioning, optical isolators, and fiber attachment, for high-speed transceiver and optical sub-assembly (OSA) applications.

Key Responsibilities

• Designing and optimizing free-space and fiber-coupled optical paths for 224G PAM4 optical modules
• Performing lens selection, positioning, alignment, and tolerance analysis for high-speed optical assemblies
• Designing and integrating optical isolators, including placement, orientation, and insertion-loss optimization
• Developing robust fiber attachment solutions, including active and passive alignment methods
• Supporting optical sub-assembly (OSA) development from concept through prototype and low-volume production
• Performing optical simulations and tolerance stack-ups to ensure yield and performance margin
• Collaborating with electrical, mechanical, and manufacturing engineers to ensure system-level performance
• Supporting optical bring-up, characterization, and debug (IL, RL, PER, extinction ratio, eye performance)
• Interfacing with vendors on lenses, isolators, fibers, ferrules, and optical components
• Generating and maintaining optical design documentation, drawings, and assembly procedures

Required Qualifications

• Bachelor’s degree (or higher) in Optical Engineering, Physics, Electrical Engineering, or related field
• Strong understanding of fiber-optic communications fundamentals, including PAM4 modulation
• Experience with optical alignment and coupling techniques (free-space and fiber-based)
• Hands-on experience with lens positioning and optical tolerancing
• Familiarity with optical isolator design and integration
• Experience designing or supporting fiber attach processes (active or passive alignment)
• Ability to work with tight mechanical and optical tolerances at high data rates

Preferred Qualifications

• Experience with 112G/224G PAM4 optical modules (QSFP-DD, OSFP, OSFP-XD, or similar)
• Experience with EML and silicon photonics-based transmitters
• Familiarity with optical simulation tools (e.g., Zemax, Code V, LightTools, or equivalent)
• Experience supporting prototype builds and low-volume production
• Knowledge of optical testing and characterization methods

What We Offer

• AGS in line with background and benchmark
• Bonus
• Canteen
