Cyber Security Research Scientist at Honeywell
Minneapolis, Minnesota, United States
Summary
👤
Senior🎓
Top SchoolWilliam Neumann is a cybersecurity research scientist and systems security engineer with over two decades of experience applying cryptography and offensive techniques to protect national-scale and industrial control systems. He blends deep cryptographic research—from digital signatures and key management to CNSA/Suite A algorithms—with hands-on penetration testing, ARM exploitation, and reverse engineering practiced at national labs and Fortune 100 companies. At Honeywell he leads research into the security of embedded and control systems, building threat assessments, vulnerability analyses, and security verification tests informed by prior work designing cryptographic parameters and verification at Rockwell. His background includes published research and teaching in cryptography from Sandia National Laboratories and practical controls engineering early in his career, giving him rare breadth across theory, hardware, and fielded systems. An active contributor to Exercism’s Swift tracks, he also brings real software craftsmanship—refactoring exercises, adding test cases, and improving CI—to developer education. He holds advanced clearances, enterprise-architect training, and a mix of language and hardware expertise (Swift, F#, OCaml, Verilog/VHDL, C) that enable pragmatic, auditable security solutions.
