Job summary

Lumilens Inc. is seeking engineers to design high-speed silicon photonic ICs, taking concepts through tapeout to silicon validation.

The role suits PhD graduates to early-career engineers (0–5 years) eager to work on production-bound systems, not just simulations. Responsibilities include designing photonic devices, running EM/circuit/thermal simulations, implementing PIC layouts, and collaborating with electronics and packaging teams for CPO/NPO systems.

Qualifications

• PhD in Electrical Engineering, Physics, or related field (silicon photonics or closely related area).
• 0–5 years of relevant experience (including fresh PhD graduates).
• Experience in design and simulation of silicon photonic devices or PICs.
• Strong understanding of guided-wave optics and device physics.
• Familiarity with tools such as Lumerical, COMSOL, or equivalent.
• Exposure to PIC layout and tapeout flows (PDK, DRC/LVS).
• Basic understanding of optical communication systems and/or RF effects.

Responsibilities

• Design and optimize silicon photonic devices and circuits, including modulators, photodetectors, and passive components.
• Perform multi-domain simulations (EM, circuit, thermal) to meet bandwidth, loss, and efficiency targets.
• Implement PIC layouts (GDS) using foundry PDKs and support tapeouts.
• Co-design with electronics and packaging teams for RF/optical systems.
• Support silicon bring-up and characterization, correlating measurements with simulations.
• Contribute to design libraries, modeling, and methodology development.
