About The Position

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.

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.

Requirements

• BS in Computer Science or equivalent.
• 5+ years of experience developing performance-critical software, with a solid understanding of systems architecture, operating systems, and modern frameworks and their performance characteristics.
• Expertise in low-level CPU programming, concurrency models, and performance engineering techniques.
• Proven ability with a wide range of profiling tools (e.g., Xcode Instruments, Android Studio Profiler, VTune, Linux perf, SystemTap, proprietary tools).
• Effective communication of intricate performance analysis to diverse stakeholders, including actionable recommendations.

Nice To Haves

• Proven ability to collaborate effectively within a team and thrive in fast-paced, deadline-driven environments.
• Experience optimizing performance across various domains on multiple platforms (e.g. iOS, Android, Desktop, Server).
• Demonstrated strong problem-solving, analytical, and rapid learning abilities.
• Knowledge of power management and battery-life analysis techniques.
• Experience with Mac or iOS application development using Swift or Objective-C.

Responsibilities

• Identifying, diagnosing, and resolving complex performance issues across our applications, systems, core frameworks, and background services (daemons).
• 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.
