# Scientific Computing Engineer, Numerical Solvers

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 work at the intersection of optics, software, and data. 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 a Scientific Computing Engineer to own and develop significant parts of our in-house numerical solver, from mathematical formulation to tested, production-quality code behind a stable interface: numerical methods, iterative solvers, validation and performance optimization amongst others. Working closely with our technical lead, you'll shape how the solver is formulated, implemented and run on GPU and CPU hardware. You'll work with the algorithm team, who use the solver, and with the software team, who integrate and deploy it in our product. You own your parts of the solver
