## About the role

Neurophos is looking for a Silicon Photonics Engineer to lead the receiver (Rx) photonic integrated circuit for our OPU platform, including the T100 optical AI inference chip. You will own the Rx PIC from photodetector device design through chip-level architecture: how light reaches the chip, how it is coupled and routed, and how large photodetector arrays convert it into clean, high-speed electrical signals for the TIAs. You will take designs through tapeout and silicon validation. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- PhD in a relevant field, such as Electrical Engineering, Applied Physics, or Physics
- 3 years of relevant experience in high-speed silicon photonics, focused on photodetectors and receiver PICs
- Hands-on design experience with Ge-on-Si (or equivalent) high-speed photodetectors, including the trade-offs among responsivity, bandwidth, capacitance, and dark current
- Proficiency with photonic and device simulation tools (e.g., Lumerical/Ansys, COMSOL, Synopsys TCAD, or equivalent) and with circuit-level modeling of photodetectors
- Experience laying out and taping out in a silicon photonics foundry PDK (e.g., KLayout, gdsfactory, Cadence Virtuoso, or equivalent)
- Working knowledge of optical receiver fundamentals: TIA interfacing, noise, sensitivity, and PAM4 signal integrity
