Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Design and optimize high-speed silicon photonic integrated circuits from concept through tapeout and silicon validation. Collaborate with electronics and packaging teams to implement CPO/NPO systems and drive design iterations based on characterization data.
Requires a PhD in Electrical Engineering, Physics, or a related field with 0-5 years of experience in silicon photonics. Proficiency in simulation tools like Lumerical or COMSOL and familiarity with PIC layout flows are essential.
You will design high-speed silicon photonic integrated circuits operating at the limits of bandwidth and integration, and take them from concept → tapeout → silicon validation.
This role is suitable for strong PhD graduates through early-career engineers (~0–5 years experience) who want to work on real, production-bound systems, not just simulations.
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
PhD in Electrical Engineering, Physics, or related field (silicon photonics or closely related area)
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
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)
Work on real products at 200G/lane+, not just research prototypes
Direct impact on AI infrastructure and hyperscale systems
Fast iteration cycles from design → silicon → system
High ownership early in your career
Comprehensive benefits package including health insurance
Collaborative environment with world-class engineering and R&D teams
