About the role

From chip-to-chip optical interconnects to scalable photonic engines, Lumilens is unlocking a new era of computing faster, cooler, and massively more efficient.
This isn't incremental innovation, it's a ground-floor opportunity to rethink the optical layer from the silicon up.
You'll work alongside a team of world-class engineers solving some of the hardest challenges in optics, systems, and scale.

Lead hardware-focused system integration for 51.2T and next-gen switches, including optical module bring-up, lab validation, and performance verification for 800G/1.6T transceivers.
Collaborate across optical, hardware, signal integrity, thermal, mechanical, and software teams to ensure robust integration of optical modules into AI networking environments.
Develop and maintain test procedures, characterization reports, application notes, and supporting scripts or tools to improve validation efficiency and customer support.

Working knowledge of signal integrity, power integrity, thermal considerations, and hardware validation methodologies for high-speed systems.
Excellent analytical, communication, and customer-facing skills, with the ability to translate complex hardware and system issues into actionable solutions.

Debug complex interoperability issues spanning optical modules, DSP settings, host interfaces, switch platforms, and Layer 1 link behavior.
Execute board- and system-level testing using lab equipment such as oscilloscopes, BERTs, VNAs, and protocol analyzers to characterize link performance and root-cause failures.
Review schematics, layouts, and system configurations to identify signal integrity, power integrity, and integration risks during bring-up and qualification.
Stay current on industry standards and emerging technologies in AI networking, optical transceivers, module management, and high-speed electrical/optical interfaces.
Bachelor's degree or higher in Electrical Engineering, Computer Engineering, Physics, or a related field.
Strong understanding of optical transceivers, including module architectures, control interfaces, configuration protocols, and performance metrics.
Extensive hands-on experience with DSP tuning, optical transceiver configuration, and high-speed link bring-up and debug.
Deep familiarity with AI networking switch architecture, host electrical interfaces, and system-level integration of optical modules.
