Summary
👤
Senior🎓
Top SchoolCristian Mattarei is a Senior Formal Verification Engineer with nine years of experience applying SAT/SMT and symbolic model checking to prove correctness of complex SoCs across Apple’s A, M, S and R product lines. He holds a PhD from Università di Trento and has an academic pedigree including postdoctoral work at Stanford and research stints at FBK and NASA, where he focused on safety, reliability and formal validation for critical systems. At Apple he brings research-grade verification techniques into production silicon, and his open-source contributions to pySMT (including a PDR example and model-checking fixes) reflect hands-on expertise with SMT tooling. Notably, he has built translators and solvers (Altarica2SMV, MathSAT3D) for industrial partners such as Dassault and Airbus, showing a rare blend of theoretical depth and practical engineering for safety-critical domains.
