Vulnerability Researcher - Security Engineering & Architecture at Apple
Greater Seattle Area United States
Summary
👤
Senior🎓
Top SchoolJewell Seay is a vulnerability researcher and security engineer with 13 years of experience securing platforms at Apple, Google, and Microsoft, specializing in finding flaws in Apple products and cloud compute back-ends. He blends deep low-level expertise in C/C++, Python, and multiple assembly architectures (x86, ARM, PowerPC) with practical skills in reverse engineering, hardware emulation, compiler and toolchain creation, and platform security. Jewell has built custom architectures and full toolchains for emulation, debugging, compilation, and assembly, enabling reproducible vulnerability discovery across diverse hardware. His background includes designing security for Azure Sphere IoT and Windows internals, plus hands-on research at Raytheon and Battelle, reflecting both product-focused and research-driven security roles. An active contributor to challenging reverse-engineering projects—such as back-end work on the popular Paper Mario decompilation—he combines rigorous exploit discovery with robust build and heap-management fixes. Based in the Greater Seattle Area, he brings a rare mix of hardware-software fluency and practical tooling that surfaces subtle, non-obvious attack surfaces.
