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.
Responsibilities
- Provide expert technical support for 51.2T and next-generation switch architectures, with a strong focus on 800G and 1.6T optical transceivers
- Serve as the primary customer-facing technical lead, translating customer requirements into system-level solutions
- Lead customer demos, evaluations, and hands-on system bring-up, including switch configuration, link validation, and performance tuning
- Collaborate cross-functionally with optical, ASIC, hardware, software, mechanical, and thermal engineering teams to ensure seamless product integration
- Partner with silicon, EIC, and system teams to support end-to-end bring-up from chip-level to module- and system-level integration
- Engage with external ecosystem partners (foundries, ASIC vendors, module partners) to align on technical capabilities, integration, and performance targets
Requirements
- Experience interfacing with foundries and understanding semiconductor development and manufacturing flows
- Proven ability to work across cross-functional and geographically distributed teams
- Excellent analytical, communication, and customer-facing skills, with the ability to translate complex issues into actionable insights
- Strong ability to work independently while influencing across complex organizations
- Deep experience engaging with CPO/NPO (Co‑Packaged Optics / Near‑Package Optics) architectures, including system tradeoffs, optical/electrical integration considerations, and customer-facing technical discussions.
- Hands-on experience supporting AI infrastructure deployments, with a focus on scale‑up (intra‑node/interconnect) and scale‑out (cluster/fabric) architectures for high‑performance workloads.
Nice to have
- Debug and resolve complex interoperability issues across AI networking switches, DSPs, and high-speed optical modules
- Contribute to industry standards bodies (e.g., MSA) and stay current with emerging trends in AI networking, optical interconnects, and switch architectures
- Operate effectively across global teams, driving alignment and execution across multiple geographies
- Master's degree or higher in Electrical Engineering or a related technical field
- Strong understanding of optical transceivers, including architecture, configuration, and performance characteristics
- Extensive hands-on experience with DSP bring-up, transceiver configuration, and high-speed link debugging
- In-depth familiarity with AI networking switch architectures and Layer 1/Layer 2 configurations
- Experience working with 800G optical modules and 51.2T-class switches (1.6T and next-gen systems strongly preferred)
Compensation
- Competitive salary and significant equity compensation in a rapidly growing, well-funded startup.
