Pranjal Jumde is a security-focused engineering leader with 11 years of experience building and hardening software across browsers, containers, and cloud-native platforms. Currently a Team Lead in Austin, he previously served as Principal Security Engineer at Brave where he integrated privacy and payments features, added WebAuthn on iOS, and contributed to the widely known Brave browser codebase. His background spans vulnerability research and exploit reverse-engineering at Adobe, kernel-level syscall controls for container security at StackRox, and fuzzing and code audit work at Apple and CMU. An active open-source contributor, his commits to Brave improved build automation, URL handling, cookie and certificate security, and iOS download performance—demonstrating both deep systems chops and practical automation skills. He also authored content on Kubernetes security and holds an MS in Information Security from Carnegie Mellon, combining rigorous academic training with hands-on remediation experience. Notably, he blends low-level defensive work (syscall limiting, certificate pinning) with higher-level product integrations, making him effective at translating research into production-ready protections.
