Facebook is accessed from an increasing number of mobile devices with extremely different performance characteristics. Despite a general trend towards faster devices over time, hardware improvements alone cannot be relied upon to improve the performance of our apps. Efficient use of device resources is key and scaling that to the wide variety of mobile devices is challenging.
The Infrastructure and Interfaces team owns performance of the core Facebook iOS and Android app. We have deep knowledge of mobile OS platforms and are experts at efficient use of device resources to enable our app to run in resource constrained environments. We own high-visibility performance metrics such as app cold start, install size, disk footprint, memory footprint, battery utilization, and more. These have a large and direct impact on over 2 billion Facebook users and is key to enabling the next billion people to access Facebook.
Our team is growing and we are looking for performance-minded engineers, who are passionate about building performant apps. The ideal candidate is comfortable digging into complex systems, identifying optimizations, and working with different feature teams to develop solutions. You will influence the development of performance tools for investigation, regression tracking, and metrics reporting and own performance optimization efforts. These solutions often span multiple layers of the app and require creative, unconventional thinking. As part of a world-class engineering team, you will apply performance best-practices from across the industry to a popular mobile platform.
