About Lumilens

At Lumilens, we are building the critical photonics infrastructure that powers tomorrow’s AI supercomputing. From chip-to-chip optical interconnects to scalable photonic engines, Lumilens is unlocking a new era of computing—faster, cooler, and massively more efficient. Join our collaborative team to help shape the future of high-speed optical connectivity.

Position Overview

As a Thermal Engineer at Lumilens, you will play a key support role in developing and optimizing thermal management solutions for advanced optical interconnect products used in data center and AI infrastructure equipment, including pluggable optics, near-packaged optics, and co-packaged optics. You will work closely with senior engineers to contribute to the design, analysis, and validation of thermal solutions for high-density optoelectronic systems, ensuring product reliability and performance.

Responsibilities

• Assist in the thermal design of pluggable optics, near-packaged optics, and co-packaged optics for data center switching, compute, and interconnect equipment.

• Support the development of air-cooled and liquid-cooled thermal solutions for high-power optical and optoelectronic assemblies, such as heatsinks, thermal bridges, cold plates, coolant interfaces, and platform-level heat rejection paths.

• Contribute to thermal analysis of interactions among ASICs, DSPs, optical engines, lasers, packages, and surrounding mechanical structures in dense data center deployments.

• Collaborate with system architects and senior engineers to help define thermal requirements for data center equipment at rack-level, chassis-level, and module-level, under both air and liquid cooling conditions.

• Apply working knowledge of liquid-cooling technologies used in data center systems, including cold plates, manifolded liquid loops, coolant distribution concepts, and thermal interfaces.

• Assist in evaluating tradeoffs between air cooling and liquid cooling for power-dense electronics and optoelectronic assemblies.

• Gain familiarity with the thermal challenges unique to near-packaged and co-packaged optics, such as proximity to hot ASICs, optical temperature sensitivity, thermal isolation, and serviceability constraints.
