About Lumilens
At Lumilens, we are pioneering the essential photonics infrastructure that will drive the AI supercomputing revolution of the future. From chip-to-chip optical interconnects to scalable photonic engines, we are unlocking a new era of computing that is faster, cooler, and significantly more efficient.
Backed by Mayfield and led by industry veterans who have built and scaled transformative technologies, we are a well-funded startup. This is not just about incremental innovation; it’s a unique opportunity to fundamentally rethink the optical layer from silicon upwards. You will collaborate with world-class engineers to tackle some of the most challenging problems in optics, systems, and scalability. Each line of code, design decision, and breakthrough you contribute will play a vital role in shaping the infrastructure of tomorrow.
If you seek a mission-driven environment with momentum and the chance to make a significant impact, join us on this exciting journey. We are just getting started.
About the Role
As an Optical Design Engineer, you will be instrumental in developing and validating the coupling optics essential for delivering optical signals of up to 1.6 Tb/s into our customers’ networks.
Primary Duties & Responsibilities
Leverage raytracing software tools (e.g., Zemax) to conduct optical simulations and design lens and fiber-based coupling solutions for Silicon Photonics-based electro-optical components.
Consult with suppliers on optics design concepts and solutions to enhance the performance of optical transceivers.
Design and execute experiments to assess the performance of optical coupling solutions.
Offer expert technical support to mechanical designers and process engineers to ensure optimal performance under realistic manufacturing conditions.
