Job description

Analog/mixed signal design engineer for high-speed optical transceivers

Santa Clara, CA, USA

About the Role

At NcodiN, we are redefining the future of AI computing. Our breakthrough optical interposer enables the next generation of AI system to scale beyond the copper wall. With the world’s smallest laser integrated on silicon, we eliminate traditional driver and modulator overhead and redefine system power and area efficiency. Joining NcodiN today means becoming part of a bold, fast-growing company backed by industry leaders.

We are seeking highly motivated and technically strong Analog/Mixed‑Signal IC Design Engineers to join our high-speed optical transceiver development team. The position title and level will be determined based on the candidate's experience and qualifications. You will work closely with photonics, systems, packaging, and product engineering groups to architect, design, and productize cutting‑edge electro‑optical interconnects that enable Ncodin’s optical I/O platform.

This role is ideal for an engineer who thrives in fast‑moving startup environments, enjoys owning architecture‑to‑silicon execution, and wants to help build transformative optical interconnect technology.
