Senior🎓
Top SchoolHiroki Suezawa is a Staff Security Engineer based in Tokyo with 8+ years specializing in infrastructure and DevOps security, currently at GitLab after progressing from senior roles there and at Mercari. He blends deep offensive-minded knowledge of attack flows, incident response, and network protocols with hands-on software engineering in Go and Python to design secure cloud, Kubernetes, and CI/CD architectures. Hiroki contributes to open source security tooling—adding detection rules to Falco and SAST checks to gosec—and publishes practical threat-modeling and Kubernetes security content used in industry trainings. Known for automating detection and response (including anti-phishing systems) and building secure-by-default production patterns, he pairs SRE collaboration with IaC and monitoring expertise to reduce operational risk. An under-the-radar strength is his track record of translating SOC-level forensics into proactive security automation and developer-facing controls.
