Job Summary

We are seeking an experienced Mechanical/Packaging Design Manager to lead the mechanical and packaging design for our next-generation 1.6T client-side optical transceivers. The ideal candidate will have a strong background in high-speed optical module packaging, thermal management, and Chip-on-Board (COB) assembly processes.

This role requires deep expertise in optical coupling, die bonding, wire bonding, and precision alignment techniques, ensuring high-performance, manufacturable, and reliable optical modules. The candidate will work closely with optical, electrical, and manufacturing teams to optimize module performance, manufacturability, and cost efficiency.

Key Responsibilities

• Mechanical & Packaging Design for High-Speed Optical Modules

  • Lead the mechanical and packaging design for 1.6T optical modules.
  • Optimize module housing, PCB layout integration, and thermal dissipation strategies.
  • Ensure designs meet industry standards (MSA, IEEE, Telcordia, etc.) and customer requirements.

• Advanced module Packaging & Assembly

  • Design and develop optical module packaging for high-speed interconnects.
  • Work on die bonding (DB), wire bonding (WB), and optical coupling (fiber, lens, and mirror integration).
  • Develop precision assembly and alignment techniques to ensure high optical coupling efficiency.
  • Collaborate with process engineers to optimize epoxy dispensing, underfill, and encapsulation.

• Thermal Management & Reliability Engineering

  • Develop thermal solutions (heat sinks, vapor chambers, TIMs, and metal housings) to optimize heat dissipation.
  • Conduct thermal simulations (ANSYS, FloTHERM, Icepak) to ensure module reliability.
  • Improve module mechanical robustness, shock/vibration resistance, and long-term stability.

• Process Optimization & DFM/DFA

  • Work with manufacturing and contract manufacturers (CMs) to ensure high-yield, cost-effective production.
  • Improve DFM (Design for Manufacturability) and DFA (Design for Assembly).
  • Develop process flow and standard operating procedures (SOPs) for packaging and assembly.

• Cross-Functional Collaboration & Project Leadership

  • Coordinate with optical, electrical, and test engineers to optimize module performance.
  • Interface with suppliers and assembly partners to improve material selection and process quality.
  • Mentor junior engineers and contribute to design reviews, failure analysis, and continuous improvement.

Required Qualifications

• Education & Experience:

  • Bachelor’s or Master’s degree in Mechanical Engineering, Packaging Engineering, Optical Engineering, or a related field.
  • 5+ years of experience in mechanical design and packaging for optical transceivers or semiconductor components.
  • Prior experience in 800G/400G client-side optical modules or similar high-speed optical interconnects is highly preferred.

• Technical Skills:

  • Proficiency in mechanical CAD software (SolidWorks, AutoCAD, etc.).
  • Strong experience in thermal management techniques and simulation tools (ANSYS, FloTHERM, Icepak, etc.).
  • Deep understanding of module assembly, including die bonding (epoxy or eutectic), wire bonding (gold, aluminum), and optical alignment.
  • Knowledge of optical coupling techniques (active/passive alignment, lens design, fiber attachment).
  • Experience in precision machining, CNC, die-casting, and injection molding for high-speed modules.

• Soft Skills & Other Requirements:

  • Strong analytical and problem-solving skills.
  • Ability to collaborate with cross-functional teams (optical, electrical, process engineers, and manufacturers).
  • Fluent in English (Mandarin is a plus, depending on location and suppliers).
  • Experience with MSA (Multi-Source Agreement) compliance for optical transceivers is a plus.
