About Zack Stonich

U.S. Citizen | Senior QA/SDET Leader | Immediately available for new opportunitiesI’m a quality-focused engineering leader with 20+ years in software testing, QA leadership, and secure software delivery. Throughout my career, I’ve developed a reputation for being relentless in finding defects others miss—my friends call me a savant at deep bug hunting.I have a high passion and affinity for discovering and fixing issues, whether they’re subtle integration bugs, performance bottlenecks, or security vulnerabilities hiding in complex systems. Security has always been a personal and professional interest for me. I enjoy using static and dynamic code analysis tools, fuzzers, and exploratory techniques to uncover security defects, and I love thinking deeply about design and implementation to identify vulnerabilities in business logic before they reach customers.After serving as a QA director, I returned to a hands-on role because I missed the craft of bug hunting and the satisfaction of helping teams deliver robust, secure software. For fun, I’ve also returned to school at night, currently working toward a degree in cybersecurity to expand my technical depth in this space.I’m particularly interested in opportunities at security tooling and platform companies, where I can blend my extensive testing and leadership background with my passion for bug hunting and security to help build products that protect customers.Specialties: Bug hunting, security testing, static/dynamic code analysis, test automation strategy, exploratory testing, software testing leadership, mentoring QA teams.
