Senior Silicon Photonics Engineer
Lumilens· Engineering
SingaporeFull-timePosted 2mo ago
About the role
Design high-speed silicon photonic integrated circuits from concept to tapeout and silicon validation, suitable for PhD graduates through early-career engineers (0–5 years). Focus on production-bound systems and real-world implementation.
Responsibilities
- Design and optimize silicon photonic devices and circuits, including: High-speed modulators (MZI, ring, advanced structures), Photodetectors and receiver building blocks, Passive components (couplers, filters, routing)
- Perform multi-domain simulations (EM, circuit, thermal) to meet targets in: Bandwidth (200G/lane+), Insertion loss, extinction ratio, efficiency
- Implement PIC layouts (GDS) using foundry PDKs and support tapeouts
- Co-design with electronics and packaging teams for CPO/NPO systems: RF effects, parasitics, signal integrity, and thermal constraints
- Support silicon bring-up and characterization: Correlate measurement vs simulation, drive design iterations and improvements
- Contribute to design libraries, modeling, and methodology development
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
