Silicon Photonics Switch Architect

About the Role
We are seeking a visionary Silicon Photonics Switch Architect to lead the definition, design, and optimization of our next-generation optical switching platforms. You will bridge the gap between optical physics, ASIC/CMOS electronics, and advanced packaging to deliver state-of-the-art optical interconnects. You will own the holistic architectural vision from concept through to high-volume
manufacturing.

Key Responsibilities
 Architecture Definition: Lead the system and chip-level architecture for high-capacity Silicon Photonics (SiPh) switch fabrics, ensuring optimized performance, latency, and energy efficiency (pJ/bit).

 Link Budgeting & Co-Design: Develop end-to-end optical link budgets. Drive the joint optoelectronic co-design of photonic devices (modulators, photodetectors, ring resonators) alongside electronic drivers (TIA, DSP).

 System Integration: Spearhead the floorplanning and integration of SiPh chips with scaled CMOS electronics using advanced 2.5D/3D packaging and hybrid bonding.

 Design & Simulation:



Conduct rigorous trade-off analyses balancing performance, thermal management, cost, and manufacturability.

 Design for Test (DFT): Define optical test methodologies and collaborate with test and reliability teams to ensure high yield and product robustness.

 Cross-Functional Collaboration: Act as the technical anchor point, collaborating closely with hardware, RF design, packaging, and foundry engineering teams.

Qualifications & Requirements

 Education:
Ph.D. or M.S. in Electrical Engineering, Physics, Optical sciences, or a related quantitative field.
 Experience:
5+ years of industry experience in integrated photonics, with a solid focus on high-speed optical communications or photonic switching.
 Technical Proficiencies:
o Proficiency in photonic simulation tools (e.g., Lumerical, Ansys).
o Familiarity with layout and physical verification tools (e.g., gdsfactory, IPKISS, Calibre).
