Description
QuantumDiamonds transforms cutting‑edge quantum‑sensing research into production tools that let chipmakers see current flow inside advanced semiconductor devices in seconds. As a Senior Data Scientist you’ll own the end‑to‑end analytics of our quantum‑diamond microscope - optics, electronics and signal processing - and lift its performance through rigorous data‑driven engineering.
Who we are
Founded in 2022 as a spin-off of TU Munich, QD leverages quantum sensors to rapidly capture three-dimensional current maps within multi-layer chips. Our 30-strong team of physicists, engineers, and data scientists works side by side with major semiconductor manufacturers, helping them in chip debugging and accelerating their yield analysis. Backed by top-tier deep tech investors, semiconductor experts, and strategic public programs, we have ensured long-term stability, shifting from breakthrough to scale - and shaping the next chapter in chip testing.
