Software Engineer at Varian
Wettingen, Aargau, Switzerland
Summary
👤
Senior🎓
Top SchoolRoald Ruiter is a software engineer with nine years of experience who has blended academic rigor from a PhD in Applied Physics with practical engineering across industrial automation and scientific instrumentation. Based in Switzerland, he has delivered measurable impact—automating production steps to cut operator time by 90% at Flisom and improving gantry accuracy and hardware integration at inspire AG—working across C#, Python and TwinCAT. He has a track record of turning hard-to-measure problems into reliable software and hardware solutions, from first-of-its-kind spin transport measurements to enabling detection of previously undetectable materials for high-efficiency solar cells. Now at Varian, he continues to bridge research-grade problem solving with production systems, and he shares his work and experiments publicly at roaldin.ch and cookncode.com. An understated strength is his knack for establishing solid development practices and tooling that scale teams and reduce manual effort.
