Summary
👤
Senior🎓
Top SchoolTomokazu Ishii is a seasoned mechanical engineer with over 20 years of experience designing high-reliability HDD and storage mechanics, currently contributing to 3.5-inch enterprise HDD development at HGST/Western Digital. He combines deep CAD and simulation expertise (SolidWorks, NX, CATIA, ANSYS, Matlab/Simulink) with hands-on component evaluation using optical metrology and LDV, enabling designs that balance strength, dynamics, and durability. His career spans Japan and a two-year stint in California, reflecting cross-cultural collaboration on small form factor and enterprise HDD programs with US teams. He has a history of extending CAD functionality through APIs and practical programming skills (C, Fortran, Perl), which he leveraged for custom simulation and tooling. Earlier roles include R&D on chip placers and magnetic tape drives, where he developed original FEM-based simulation approaches for flexible media handling. Trained at the University of Tokyo, he brings a hybrid of analytical rigor and practical measurement-driven development uncommon among pure design engineers.
