Summary
👤
Senior🎓
Top SchoolPierre Payen is a software engineer and mentor with a PhD in applied mathematics and 10 years of experience building and optimizing SPICE circuit simulators at Siemens EDA. He specializes in hierarchical solver development, AC and noise analysis, performance and memory optimization, and tackling convergence challenges in large legacy codebases. At Siemens he combines deep numerical modelling expertise with pragmatic C/C++ engineering, developer tooling (Gerrit/Jenkins/GitLab) and hands-on debugging using tools like Valgrind and Vtune. He mentors new hires, runs team activity reporting, and has created tailored generative-AI SKILLs to accelerate work across multi-repo codebases exceeding 10M lines. His background in electromagnetic wave diffraction research and HPC fluid dynamics gives him uncommon strength in applied numerical methods and algorithmic rigor when solving production-scale simulation problems.
