Summary
👤
Senior🎓
Top SchoolSemih Özmen is a Software Architect with 11+ years of hands-on experience building and modernizing CAD/CAE/FEM systems and currently leading a cross-team software domain at ASML. He blends deep academic research—PhD-level work in computational methods and GPGPU/parallel computing—with practical delivery, having driven architectural renewals of critical geometry engines and migrated codebases from 2M to 17M LOC. Semih has owned end-to-end CAD/CAE features without third-party libraries, tackling hard problems like 3D B-rep boolean ops, clash detection, numbering and hidden-line removal, and has implemented IFC and interoperability with AutoCAD, Tekla and AVEVA E3D. At Trimble he helped refactor the computational geometry engine for Tekla Structures, and his open-source contributions include backend work on the widely used PETSc numerical library. He is skilled at transforming legacy middleware into scalable, testable designs in resource-constrained, mission-critical environments while coaching teams to execute on that vision. Colleagues value his rare combination of deep numerical/geometry expertise, system-level pragmatism, and proven leadership across research and product contexts.
