Design, build, and maintain a modular Swift SDK used by developers across Apple platforms
Work on crash reporting, hang detection, performance monitoring, and telemetry instrumentation
Build reliable mechanisms for offline storage, batching, retries, and data delivery under mobile runtime constraints
Contribute to SDK architecture, API ergonomics, and backward compatibility
Design and evolve APIs with a focus on stability, clarity, and long-term compatibility
Debug complex issues across devices, OS versions, and app environments, including threading, memory, and lifecycle challenges
Develop and maintain capture services for networking, user interactions, and system events, leveraging frameworks such as MetricKit
Optimize startup performance, binary size footprint, memory usage, and thread safety
Coordinate with cross-platform SDK teams (React Native, Flutter, Unity) to ensure native SDK changes do not introduce downstream breaking issues
Collaborate on OpenTelemetry alignment and upstream contributions
Partner with Product and Customer Success to incorporate developer feedback

Requirements
