Frameworks Performance Engineer

Our Performance Team is looking for a well-rounded Performance Engineer with a balanced focus on both core frameworks and background services (daemons). You will dive deep into our system architecture, establish performance baselines, solve complex performance issues, and build the systems that prevent regressions before they happen. In this role, you will work with other performance and client engineers, providing the critical data and insights that guide our engineering teams to build efficient, responsive, and robust experiences.

Description

This is a hands-on performance engineering role equally focused on identifying, diagnosing, and resolving complex performance issues across our applications, systems, core frameworks, and background services (daemons). A major part of your responsibility will also involve designing and implementing a comprehensive, automated power and performance regression testing strategy, targeting critical metrics like latency, memory, CPU utilization, I/O throughput, power efficiency, and overall system responsiveness across all platforms.","responsibilities":"Analyze and resolve complex performance issues in the overall system bottlenecks, existing and upcoming features..
