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

This role is for a senior-level Mobile Engineer with a deep interest in the "guts" of mobile development—specifically SDKs and library architecture—rather than just building user-facing apps. You should have a strong command of either iOS (Swift/Obj-C) or Android (Kotlin/Java) and experience building performance-sensitive, platform-level code that other developers rely on. Grafana Labs is a legendary remote-first, open-source organization. This position offers a highly technical challenge: integrating mobile signals into the OpenTelemetry ecosystem. Standout perks include a generous 30-day annual leave policy (including company-wide shutdown days), RSU grants for all employees, and a culture that actively encourages the use of modern AI coding assistants to speed up your workflow. **You might be a good fit if you...** * Have experience maintaining mobile SDKs or platform libraries used by external teams. * Are obsessed with performance metrics like startup time, memory footprints, and network efficiency. * Are comfortable navigating the ambiguity of open-source projects and contributing to communities like OpenTelemetry. * Live in Sweden, Spain, Germany, or the UK and prefer a high-autonomy, fully remote environment.
