Apple is where individual imaginations gather together, committing to the values that lead to great work. Every new product we build, service we create, or Apple Store experience we deliver is the result of us making each other’s ideas stronger. That happens because every one of us shares a belief that we can make something wonderful and share it with the world, changing lives for the better. It’s the diversity of our people and their thinking that inspires the innovation that runs through everything we do. When we bring everybody in, we can do the best work of our lives. Here, you’ll do more than join something — you’ll add something. The Core Runtimes Trace Technologies Team within Apple’s Core OS organization is looking for an enthusiastic systems engineer interested in developing system software for introspection capabilities across Apple’s operating systems. Your work will power tools that shine a light on dark corners of the system by identifying critical performance and correctness bugs invisible to traditional instrumentation or sampling-based tools. Join a passionate, highly skilled team focused on building next-generation performance and analysis insight capabilities powered by custom-designed Apple Silicon introspection technologies. This is an incredible opportunity to tackle challenging problems spanning OS integration, SoC and CPU micro-architecture analysis, and hardware-software co-design that directly impacts every Apple device.
