Software Engineer - Systems

APPLE INC has the following available in San Diego, California. Design and develop media systems software, including using advanced system debugging, sampling, and profiling tools, such as XCode instruments, DTrace, GDB/LLDB, Valgrind, AddressSanitizer, and command of underlying architecture and implementation of UNIX-based operating systems including: filesystem interfaces, IPC primitives, messaging, RPC, synchronization, notification, Memory Management, OS X processes, POSIX threads, scheduling, priority propagation, etc. Develop features for media systems frameworks running on iOS, macOS, tvOS, and analyze correctness, reliability and performance of existing software. Develop cross-platform software and perform deep analysis of the capabilities and limitations of each run-time environment including CPU, battery life impact, reconfiguration at run-time and impact to multi-device ecosystem features. Tune new and existing algorithms for streaming media playback performance. Algorithms, such as Adaptive Bitrate (ABR) selection heuristics used in streaming playback implementations. Design, implement and configure of test-beds and simulation software for large scale validation, including designing dedicated laboratory setups that re-create or simulate a large number of use cases. Contribute to media systems design from specification to prototype and implementation, including new capabilities and features for Apple's devices (e.g., ability to download HTTP Live Streaming assets, and play them locally on an Apple device), and create new APIs (Application Programming Interfaces) to be used by software third-party developers to develop applications for Apple's hardware. Design, assemble, and maintain Streaming Lab infrastructure hardware to enable testing and troubleshooting of streaming algorithms. Monitor and perform analysis on large quantities of user field data to identify trends and issues across the Apple family of devices. 40 hours/week.
