Rockstar🎓
Top SchoolZachary Koopmans is a software engineer with a decade of technical and leadership experience, combining hands-on kernel-level back-end work at Google with operational command roles in the U.S. Air Force. At Google he contributes to gVisor—the high-profile application kernel for containers used in GKE Sandbox—adding ARM support, security hardening against SMT side-channel risks, and performance-regression benchmarks integrated into CI/CD. His military service included leading developer teams to rapidly deliver mission-critical cyber capabilities and managing malware reverse-engineering and simulation tooling. He holds a MS in Computer Science from Georgia Tech and a background in computer engineering, mathematics, and even formal music performance, reflecting a rare interdisciplinary perspective. Willing to relocate to the Seattle or Portland areas, he brings a proven ability to ship secure, high-performance systems under pressure and an appetite for low-level systems work that impacts large-scale container platforms.
