Application Engineer (Device Expert)

About Invisix Semiconductor manufacturers can't build what they can't measure. Invisix Measuring Systems is a fast-growing scale-up in the high-tech industry, developing next-generation metrology solutions for the semiconductor sector. We reconstruct the detailed 3D geometry of next-generation chips, geometry no one else can see. We were founded by former ASML experts in metrology, and we're now scaling the team to bring that technology to market. We're a small team, but the depth of knowledge inside Invisix is anything but small. Our culture is professional and fast-paced, with short communication lines and a strong sense of shared purpose. Everyone here is committed, and everyone knows their work directly contributes to something bigger.
