Facebook is accessed from an increasing number of mobile devices with extremely different performance characteristics. Furthermore, network quality varies dramatically according to connection type, device, and geographical factors. Despite a general trend towards faster devices over time, hardware improvements alone cannot be relied upon to increase the speed of our application user experience. Developing a performance user experience that scales to all devices is both a difficult and meaningful challenge that has impact on every mobile Facebook user. Facebook is looking for performance-minded engineers to help increase the speed of our mobile experiences, while simultaneously reducing consumption of key resources. We are looking for engineers who are comfortable digging into complex system, identifying optimizations, and working with feature teams to develop solutions. These solutions often span multiple layers of application and require creative, unconventional thinking. You will influence the development of performance tools for investigation, regression tracking, and data reporting. As part of a world-class engineering team, you will apply performance best-practices from across the industry to popular mobile platforms.
