About the role
Thermal Engineer at Lumilens focused on developing and optimizing thermal management solutions for advanced optical interconnect products in data center and AI infrastructure, collaborating with senior engineers to design, analyze, and validate thermal solutions for high-density optoelectronic systems.
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.
