Rockstar🎓
Top SchoolChris Koch is a Staff Software Engineer with 12 years of experience building low-level security and infrastructure software across hardware, firmware, kernel, and OS layers. Based in San Francisco, he led infrastructure security at Google focused on verified/measured boot, attestation, physical-attack mitigations, and cloud bare-metal hardening before moving to Snowflake. He combines production-grade systems engineering with hands-on open-source contributions—helping gVisor's network and filesystem code and improving DHCP and router implementations in Go. Comfortable navigating both research-grade security properties and pragmatic engineering, he often surfaces subtle memory and protocol correctness fixes that prevent real-world outages and leaks. His background in systems administration and teaching informs a practical, mentor-oriented approach to complex, auditable security work.
