As a member of the performance team, you will contribute to investigating cases of poor performance in media applications. You will identify performance bottlenecks and hot-spots in the CoreMedia software stack, explore new tools and methodologies for performance measurement, and build robust statistical models to detect regressions. Analysis of large-scale performance telemetry data will be used to learn trends and drive future improvements. You will also create and defend performance benchmarks for media use cases and collaborate with other CoreMedia engineers to implement optimizations, working across power and performance teams at Apple to drive improvements in tools and measurement techniques.
