Characterization Engineer
About Kandou AI
At Kandou AI, we are redefining the economics of AI infrastructure. Our mission is to democratise AI by significantly reducing the Total Cost of Ownership (TCO) of hardware systems — a critical barrier to scalable adoption.
Our proprietary MIMO‑over‑copper technology powers a high‑performance, chiplet‑based AI memory fabric that is both scalable and energy‑efficient. Unlike traditional interconnects, our solution reduces power consumption while preserving high bandwidth and ultra‑low latency, unlocking unprecedented efficiency for AI training and inference at scale.
Kandou AI’s architecture is not an incremental improvement — it represents a foundational shift in how AI hardware is built for the future.
We are actively seeking a
Characterization Engineer
for our lab in
Lausanne, Switzerland
.
Role Overview
The Characterization Engineer will lead end‑to‑end characterization of high‑speed silicon devices and SerDes operating at symbol rates above 20 Gbaud. This role is central to validating Kandou’s next‑generation high‑speed analog and mixed‑signal designs, ensuring performance, robustness and efficiency across PVT conditions.
You will work hands‑on in the lab, collaborating closely with IP architects, digital and analog design teams, and contributing directly to the productization of breakthrough interconnect technology.
