Senior Silicon Photonics Engineer

The role

You will design high-speed silicon photonic integrated circuits from concept to tapeout and silicon validation. You will work on real, production-bound systems including high-speed modulators, photodetectors, and passive components.

What you will do

• Design and optimize silicon photonic devices and circuits
• Perform multi-domain simulations for bandwidth, insertion loss, extinction ratio, and efficiency
• Implement PIC layouts using foundry PDKs and support tapeouts
• Co-design with electronics and packaging teams for CPO/NPO systems
• Support silicon bring-up and characterization
• Correlate measurement vs simulation
• Drive design iterations and improvements
• Contribute to design libraries, modeling, and methodology development

Required 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

Nice to have

• Experience with high-speed devices (>100 GHz bandwidth or equivalent)
• Exposure to CPO/NPO or optical transceiver architectures
• Familiarity with SiPh + III-V integration
• Experience with inverse design / adjoint methods (e.g., Meep)

Benefits

• Comprehensive benefits package including health insurance
