• Familiarity with the LaunchDarkly product and SDKs is a plus.
• Experience using AI tooling to improve mobile development efficiency.
• Demonstrated ability to design and maintain robust mobile APIs.
• Strong understanding of algorithms, data structures, concurrency, and mobile performance optimization.

• Self-driven, curious about mobile observability technologies, and committed to continuous learning.

Responsibilities

• Develop and enhance native mobile SDKs (Android Java/Kotlin and/or iOS Swift / Objective-C) for telemetry ingestion, including session replay, logging, tracing, and metrics.
• Optimize mobile data pipelines for high throughput and low latency telemetry reporting.
• Drive mobile-focused features end-to-end: prototyping, API design, SDK development, and performance validation.
• Collaborate on enhancements to mobile-specific OpenTelemetry SDK integrations.
• Partner with product managers, UX designers, and backend engineers to deliver high-quality mobile observability tools.
• Mentor peers and promote best practices in mobile development.
