Summary
🤩
Rockstar🎓
Top SchoolJed Davis is a seasoned software engineer with 20 years of experience building system-level infrastructure and tooling, currently at Mozilla in Boulder, Colorado. He has deep expertise in operating systems, sandboxing, IPC, and performance investigation—work exemplified by contributions to the Gecko engine and historically to the Boot to Gecko project. Prior roles on the vSphere kernel core team at VMware saw him maintain critical subsystems from memory allocators to filesystems and even modify a compiler backend. Jed blends hands-on low-level systems programming with DevOps and automation skills, improving build/flashing workflows and profiling tooling. He is comfortable refactoring legacy synchronous code into asynchronous, process-separated architectures and tackling subtle security and memory-management issues. A pragmatist with an academic foundation (MS CS, Northeastern; BA CS, Oberlin), he often surfaces design fixes that cut across component boundaries.
