Staff Mobile Engineer: Instrumentation SDK (iOS/Android) - Grafana Observability | US | Remote

Grafana Labs is a remote-first, open-source powerhouse with over 20 million users globally. They are seeking a Staff Mobile Engineer to build and evolve mobile instrumentation SDKs for iOS and Android, ensuring high performance and a great developer experience while collaborating with cross-functional teams.

Responsibilities:

• Build and evolve mobile instrumentation SDKs for iOS (Swift / Obj-C) and Android (Kotlin / Java), prioritizing performance, stability, and a great developer experience
• Design and ship SDK features such as session tracking, crash reporting, sampling strategies, automatic context propagation, and OpenTelemetry integrations
• Own projects end-to-end
• Break large, ambiguous problems into incremental deliverables: design modular solutions, ship MVPs, gather feedback, iterate quickly
• Ensure quality: automated tests, CI, documentation, and smooth, backwards-compatible upgrade paths
• Collaborate cross-functionally with backend, frontend, product, and solutions engineering to ensure cohesive end-to-end observability workflows
• Engage with the open-source community: review PRs, discuss design proposals, and help guide external contributors
• Mentor teammates, participate in technical design discussions and help shape the mobile observability roadmap

Requirements:

• Strong mobile engineering experience (one or both): iOS (Swift/Obj-C) and/or Android (Kotlin/Java)
• Demonstrated experience building or maintaining mobile SDKs, platform libraries, or other developer-facing platform code used by external developers
• Experience working with performance-sensitive code (startup time, memory, network efficiency) and making pragmatic tradeoffs
• Familiarity with OpenTelemetry (instrumentation, SDKs, collectors) or experience contributing to/maintaining OTel SDKs or similar telemetry libraries
• Excellent written and verbal communication
• Comfortable working in a fully remote, globally distributed team
• Coachable, customer-focused, and passionate about developer experience, you can do more than code: you write docs, mentor others, and shape roadmaps
• Pragmatic and comfortable navigating ambiguity: you prioritize progress over perfection and iterate quickly based on feedback
• Contributions to OpenTelemetry, crash reporting libraries, or other observability OSS
• Experience with cross-platform frameworks (React Native, Flutter) or building native bindings/bridges
• Experience with mobile security, privacy, or platform integration challenges
• Prior work on crash aggregation, session replay, or sampling for mobile telemetry
