Role Overview

We are seeking an Optical Design Engineer to lead the design and validation of coupling optics that facilitate delivering optical signals up to 1.6 Tb/s into client networks. This role demands expertise in optical system design and hands-on laboratory experience to ensure optimal signal transmission performance.

Key Responsibilities

• Apply raytracing software such as Zemax to simulate and design lens and fiber-based coupling solutions tailored to Silicon Photonics electro-optical components.
• Collaborate with suppliers by offering expert advice on optical design concepts to enhance the performance of optical transceivers.
• Devise and execute experiments aimed at assessing optical coupling solution effectiveness.
• Support mechanical designers and process engineers technically to achieve peak performance within realistic manufacturing parameters.

Qualifications & Skills

• Possess a Master's degree in optical engineering or a similarly relevant field; a Ph.D. is highly desirable.
• A minimum of two years' direct experience in optical system design.
• Demonstrated proficiency with raytracing tools including Zemax or CodeV (covering sequential/non-sequential raytracing, tolerancing, Monte Carlo simulations, and ZOS-API scripting).
• Experience with MATLAB or Python programming.
• Knowledge of JMP is advantageous.
• Practical lab experience conducting optical testing and designing setups.
• Familiarity with process control, quality assurance, and optical communication standards (such as IEEE and MSA) is a plus.
• Strong analytical and creative problem-solving abilities applied to complex technical challenges.
• Proven ability to collaborate effectively with international teams across different time zones.
• A self-starter mindset, capable of managing multiple tasks and meeting deadlines independently.
• Organized and detail-oriented with adaptive strategies to overcome obstacles.
• Excellent communication skills.
• Availability and willingness to travel approximately 20% of the time.

Additional Experience

• Exposure to photonics, telecommunications, or high-speed networking systems is beneficial.
