Details

Grafana Labs is hiring a Senior Mobile Engineer to build and evolve mobile instrumentation SDKs for iOS. The Mobile Observability initiative provides SDKs that capture traces, metrics, logs, crashes, and user sessions, with integrations for OpenTelemetry and Grafana Cloud.

Responsibilities

Build and evolve high-performance mobile instrumentation SDKs for iOS using Swift and Objective-C.
Design and ship features including session tracking, crash reporting, sampling strategies, automatic context propagation, and OpenTelemetry integrations.
Own projects end to end.
Break down large and ambiguous problems into incremental deliverables, design modular solutions, ship MVPs, gather feedback, and iterate quickly.
Ensure quality through automated tests, CI, documentation, and smooth, backward-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, 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.
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 approach to ambiguity, with an emphasis on progress, iteration, and 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.
Prior work on crash aggregation, session replay, or sampling for mobile telemetry.

Compensation

The compensation range in Spain is €82,000–€103,000 per year. Actual compensation may vary based on level, experience, and skill set. The role includes Restricted Stock Units (RSUs).

Benefits and Culture

100% remote global culture.

Global annual leave policy of 30 days per year, including three Grafana Shutdown Days, subject to local legislation.
Career growth pathways, transparent communication, high-trust teams, and an open-source-driven culture.
