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 software‑driven system integration for 51.2T and next‑gen switches, including API configuration, automation frameworks, and module management for 800G/1.6T optical transceivers.
Create and run customer demos, software workflows, and validation scripts, including switch bring‑up, link diagnostics, and performance verification.
Collaborate across software, optical, hardware, thermal, and mechanical engineering teams to ensure clean, scalable integration of optical modules into AI networking environments.
Develop scripts, tools, and automation (Python or similar) to accelerate triage, link tuning, and test execution.

Debug complex interoperability issues spanning switch OS/SDKs, DSP firmware, protocol stacks (L1/L2), and optical module control interfaces.
Stay current on industry standards and emerging technologies in AI networking, module management protocols, and switch software architectures.
Bachelor's degree or higher in Electrical Engineering, Computer Engineering, Computer Science, or related field.
Strong understanding of optical transceivers, including control interfaces, configuration protocols, and performance metrics.
Extensive hands‑on experience with DSP configuration tools, module firmware interaction, and high-speed link debugging.
Deep familiarity with AI networking switch software, including OS/SDK configuration, management protocols, and Layer 1/Layer 2 behavior.
Experience working with 800G modules, 1.6T architectures, or 51.2T switches is highly desirable.
Prior experience with leading optical-transceiver or networking-system companies is a strong plus.
