Job description

Design and implement new features and APIs for the on-device Experimentation service that is deployed across multiple Apple operating systems Develop and maintain high-performance libraries that are easy to use by developers Participate in all phases of software development cycle: from problem definition and design, through implementation, testing, and debugging Diagnose and resolve issues across different layers of the software stack Write unit and integration tests for new and existing code Work with cross-functional teams to enable developer and product features An appreciation how an OS design impacts end-user experience Working proficiency in Objective-C, Swift, C/C++, Kotlin, or similar languages Strong academic foundation in operating systems concepts, including concurrency, multi-threading, synchronization primitives (mutexes, locks, semaphores), inter-process communication (IPC), and memory management. Hands-on experience developing low-level or systems software through internships, academic capstones, coursework labs, or substantial open-source/personal projects (e.g., building a shell, multi-threaded server, user-space service, or operating system project). Excellent problem-solving, debugging, and communication skills, with a track record of collaborating effectively in team or group-project settings. Bachelor’s degree in Computer Science, Computer Engineering, or a related technical discipline (or equivalent practical experience). Prior software engineering internship experience in systems software, embedded platforms, or platform engineering. Exposure to Unix/POSIX APIs, event loops/run loops (libdispatch/GCD, kqueue, epoll), or system daemons/services (launchd, systemd). Experience in iOS, macOS, or similar operating systems An appreciation of how a platform design impacts end-user experience Experience in experimentation or A/B testing and AI Master's degree in Computer Science, Computer Engineering, or a related technical discipline (or equivalent practical experience).
