Details

Grafana Labs is hiring a Senior Mobile Engineer to build and evolve high-performance instrumentation SDKs for iOS. The role focuses on mobile observability, including traces, metrics, logs, crashes, and user sessions, with close integration with OpenTelemetry and Grafana Cloud.

This is a fully remote opportunity. Applicants currently based in Spain, Ireland, Germany, the United Kingdom, or Sweden are being considered.

Responsibilities

Build and evolve mobile instrumentation SDKs for iOS using Swift and Objective-C, prioritizing performance, stability, and developer experience.
Design and ship 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, and iterate quickly.
Ensure quality through automated tests, continuous integration, documentation, and smooth, backwards-compatible upgrade paths.
Collaborate with backend, frontend, product, and solutions engineering teams to deliver cohesive end-to-end observability workflows.
Engage with the open-source community by reviewing pull requests, discussing design proposals, and guiding external contributors.
Mentor teammates, participate in technical design discussions, and help shape the mobile observability roadmap.

Requirements

Strong mobile engineering experience with iOS using Swift and Objective-C; Android experience with Kotlin or 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, including startup time, memory usage, and network efficiency, and making pragmatic tradeoffs.
Familiarity with OpenTelemetry, including instrumentation, SDKs, and collectors, or experience contributing to or maintaining OpenTelemetry SDKs or similar telemetry libraries.
Excellent written and verbal communication skills.
Ability to work autonomously and collaboratively in a fully remote, globally distributed team.
Customer-focused, coachable, and passionate about developer experience, documentation, mentoring, and roadmap development.
Pragmatic and comfortable navigating ambiguity, prioritizing progress over perfection and iterating based on feedback.

Bonus Qualifications

Contributions to OpenTelemetry, crash-reporting libraries, or other observability open-source software.
Experience with cross-platform frameworks such as React Native or Flutter, or with building native bindings and bridges.
Experience with mobile security, privacy, or platform integration challenges.
Experience with crash aggregation, session replay, or sampling for mobile telemetry.

Benefits

Compensation in Germany of €97,000–€121,000 per year; actual compensation may vary based on level, experience, and skills.
Restricted Stock Units (RSUs).
Fully remote global culture.
