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

This role is for an experienced mobile engineer who enjoys building tools for other developers. You should have a deep understanding of either iOS (Swift/Obj-C) or Android (Kotlin/Java) and experience maintaining SDKs, libraries, or platform-level code. Ideally, you are passionate about the "guts" of mobile apps—performance, memory management, and network efficiency—rather than just building UI features. The position offers a salary range of €94,025 - €112,830 for Spain-based candidates, plus equity in the form of RSUs. As a "remote-first" company, Grafana offers significant flexibility, including 30 days of annual leave and a dedicated budget for AI coding assistants. You'll be working at the intersection of mobile development and open-source observability, contributing directly to the OpenTelemetry ecosystem. **You might be a good fit if you...** * Have shipped mobile SDKs or platform libraries used by external third-party developers. * Are comfortable navigating the nuances of performance-sensitive code like startup times and crash reporting. * Have experience with (or a strong interest in) OpenTelemetry and full-stack observability. * Thrive in a remote, autonomous environment where you can influence the product roadmap.
