Sensing & Calibration Specialist

About Invisix Invisix Measuring Systems is a fast-growing scale-up in the high-tech industry, developing next-generation metrology solutions for the semiconductor sector. We work at the intersection of optics, physics, and code. Semiconductor manufacturers can't build what they can't measure. At Invisix, we're solving one of the most technically demanding problems in chip manufacturing: reconstructing the detailed 3D geometry of the most advanced next-generation devices. Founded by two ASML veterans with deep roots in short wavelength metrology, we've spent years de-risking this technology. Now we're building the team to bring it to market. If you love to take ownership, collaborate closely with innovators who care deeply about their contributions, and want your work to matter at the frontier of what's physically possible, this is the place to be. 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. If you want to be part of shaping an industry rather than just working in it, this is the place. The role We're strengthening the team that designs the sensing, calibration and optics core of our semiconductor metrology tool. This is the part that determines how well the tool sees and measures. It's a complex optical system, embedded deep in the tool's hardware, governed as much by physics as by code. This is not a software role wrapped around someone else's physics. It's the physics and the math themselves, plus the software needed to bring them to life. Because this spectrum of expertise is wide, we have several positions open to cover it, rather than one fixed profile. If you have specialist knowledge in one of the areas below, that's reason enough to reach out. You don't need to cover all of them. Where your expertise could fit Optical system design: illumination, lenses and sensors closest to the physics of the measurement Calibration algorithms: the mathematical models and routines that keep the equipment accurate over time Physics & measurement modeling: the optical, thermal and mechanical effects that influence accuracy Wafer alignment & coordinate transformations: specifying the alignment function and the transformations that map sensor and mark detections onto wafer, stage, and tool reference frames Image processing & sensor data pipelines: turning raw sensor data into calibrated images with low latency and high throughput Whichever of these is your specialty, most of the roles we're filling also ask for some ability to turn that expertise into working software, translating a model or algorithm into a tested, reusable implementation. Is this you? Specialist, in-depth knowledge in one (or more) of the areas above. Depth in a single field matters more to…
