Senior🎓
Top SchoolJoey Jiao is a Sr. Staff Engineer based in Shanghai with over 14 years of engineering experience that spans refrigeration R&D and embedded Android systems. After a decade leading product and R&D efforts in air-conditioning firms, he pivoted in 2012 to software at Qualcomm, where he now specializes in software integration, CI, big data, Linux kernel baseporting, and Linux security. He brings a hands-on security and tooling mindset—contributing Android support to the widely used AFL++ fuzzer, including shared-memory adaptations and Frida instrumentation to expand Android fuzzing coverage. Joey combines hardware-rooted systems thinking with deep low-level Linux and Android expertise, making him effective at both debugging platform issues and driving integration at scale. His background in applied thermodynamics and product engineering gives him a rare cross-domain perspective on performance, reliability, and system constraints. Fluent in bridging legacy embedded stacks and modern continuous-integration workflows, he focuses on making complex platforms testable and secure.
