Director of Engineering at The FreeBSD Foundation
Kitchener, Ontario, Canada
Summary
🤩
RockstarEd Maste is a Director of Engineering with 20 years of experience specializing in systems-level software, cross-platform compatibility, and FreeBSD platform engineering. As a FreeBSD committer and Senior Director of Technology for The FreeBSD Foundation, he blends leadership with deep technical contributions to core open-source infrastructure. His hands-on work spans OBS Studio, pkg, Clang, and LLDB—fixing build issues, adding AArch64 support, improving debug info, and hardening debuggers on FreeBSD. He is comfortable shifting between compiler internals, package management, and runtime debugging, and consistently delivers deterministic builds and safer low-level fixes. Based in Kitchener, Ontario, he brings an uncommon mix of director-level strategy and daily commit-level craftsmanship to maintainers and product teams. Colleagues rely on him for pragmatic solutions to platform-specific challenges that often go unnoticed until they break builds or debuggers.
