o Profiling CPU and memory with Instruments and os_signpost.
o Debugging with LLDB, crash logs and os_log.
o XCTest, sanitizers, fuzzing, and xcodebuild-based CI.
o Apple Silicon and Intel.
· Experience with codebases shared across Mac, Windows and Linux.
Core skills (one or more of the areas listed below)
· Process model and IPC: launchd daemons and agents, and XPC (C API and NSXPCConnection).
