Software Engineer at BuildBuddy
Bainbridge Island, Washington, United States
Summary
🤩
RockstarKeith Smiley is a seasoned software engineer with 13 years building developer infrastructure, compilers, and mobile tooling, most recently at BuildBuddy after leading platform work at Modular and nine years as a Principal Engineer at Lyft. He blends deep systems and build expertise—Bazel, LLVM, Swift, and iOS toolchains—with hands‑on product delivery, maintaining Bazel’s iOS support and contributing to Swift and LLVM projects. Keith has a strong open-source footprint (rules_apple, rules_swift, SwiftPM, SwiftLint, RxSwift, Envoy) and founded the Mobile Native Foundation, showing commitment to community-driven tooling. Known for smoothing cross‑platform build and CI pain points, he often surfaces non-obvious platform fixes (e.g., sandboxing, linker args, compiler flags) that improve reproducibility and developer velocity.
