Application Team Lead (Architect)

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 specialists in short wavelength 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. The Role We're looking for an Application Team Lead / Architect to own our applications engineering function. You'll work directly with tier-1 semiconductor manufacturers, understanding their device architectures and process challenges, then directing a team to deliver proof-of-concept demonstrations that shape their strategic investment decisions. This is not a back-office role. It's customer facing, high pressure, and organizationally critical. You'll collaborate closely with our CEO during the transition, gradually taking over the primary customer-facing technical relationships yourself.
