Summary
👤
Senior🎓
Top SchoolJeremi Gosney is a Distinguished Engineer and cybersecurity authority with over two decades of experience spanning information security, high-performance computing, embedded Linux, and distributed systems. He pioneered GPGPU password cracking, co-developed Hashcat, and founded Terahash, scaling it into a multi-million dollar HPC business serving Global 500 companies and defense clients. His work has influenced NIST guidance, university courses, and mainstream media coverage, and he has repeatedly anticipated industry shifts—predicting containers and ARM in datacenters before they became mainstream. Jeremi combines hands-on engineering (from embedded firmware on airliners to designing turnkey GPU clusters) with strategic security leadership, including roles running security for major carriers and judging the Password Hashing Competition. Based in Austin, he also runs high-profile security events and CTFs, blending research, operations, and community stewardship. A quieter through-line in his career is building reproducible training and tooling—examples include vulnerable eLearning platforms and multiple open cryptographic tools—that accelerate security knowledge across industry and academia.
