Grafana Labs is building end-to-end observability solutions for mobile developers. This role focuses on designing and shipping high-performance, low-overhead instrumentation SDKs for iOS that capture traces, metrics, logs, crashes, and user sessions. The SDKs are tightly integrated with OpenTelemetry and Grafana Cloud, enabling mobile developers to connect mobile signals to backend and infrastructure telemetry for true full-stack visibility.
You will own projects end-to-end, from design through shipping and iteration. Key responsibilities include:
- Build and evolve mobile instrumentation SDKs for iOS (Swift/Obj-C), prioritizing performance, stability, and developer experience
- Design and ship SDK features such as session tracking, crash reporting, sampling strategies, automatic context propagation, and OpenTelemetry integrations
- Break down large, ambiguous problems into incremental deliverables; design modular solutions, ship MVPs, gather feedback, and iterate quickly
- Ensure quality through automated tests, CI, documentation, and smooth, backwards-compatible upgrade paths
- Collaborate cross-functionally with backend, frontend, product, and solutions engineering teams
- Engage with the open-source community by reviewing PRs, discussing design proposals, and guiding external contributors
- Mentor teammates, participate in technical design discussions, and help shape the mobile observability roadmap
You will work in a fully remote, globally distributed team across 40+ countries. Grafana Labs is backed by leading investors including Lightspeed Venture Partners, Sequoia Capital, and others, with customers including Anthropic, Bloomberg, NVIDIA, Microsoft, and Salesforce.
REQUIREMENTS:
- Strong mobile engineering experience with iOS (Swift/Obj-C); Android (Kotlin/Java) is optional
- 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 skills
- Comfortable working in a fully remote, globally distributed team
- Coachable, customer-focused, and passionate about developer experience; ability to write docs, mentor others, and shape roadmaps
- Pragmatic approach to navigating ambiguity; prioritize progress over perfection and iterate quickly based on feedback
- Self-starter with bias toward action and ability to run with poorly defined scopes; operate autonomously while being highly collaborative
BONUS:
- Contributions to OpenTelemetry, crash reporting libraries, or other observability open-source projects
- 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
