We’re scaling fast and staying true to what makes us different: an open-source legacy, a global collaborative culture, and a passion for meaningful work. Our team thrives in an innovation-driven environment where transparency, autonomy, and trust fuel everything we do. You may not meet every requirement, and that’s okay. If this role excites you, we’d love you to raise your hand for what could be a truly career-defining opportunity. The opportunity Grafana Observability builds end-to-end observability that spans application, infrastructure, database, browser, and mobile. Our Real User Monitoring (RUM) initiative focuses on capturing, storing, and querying high-volume user interaction data from browsers and mobile devices, enabling teams to understand real-world user experiences at scale. We’re building systems that ingest and process massive amounts of telemetry – sessions, events, traces, and logs – and make them explorable in real time. You’ll have the opportunity to work on high-performance backend systems, columnar storage databases, and intuitive frontend experiences. Our solutions are tightly integrated with OpenTelemetry and Grafana Cloud. We care deeply about performance, cost-efficiency, and developer experience across the entire stack. From instrumentation to query layer to visualization. We value open standards, great developer experience, and doing the hard engineering needed to ship reliable software at scale. You may not meet every requirement below. If this role excites you, please raise your hand. What you’ll be doing • Build and evolve fullstack features for RUM, starting with the frontend user experience that spans our backend services, APIs, storage systems. • Design and implement systems that ingest, store, and query high-cardinality, high-volume telemetry data using columnar/analytical databases. • Develop performant query layers and APIs that power real-time exploration of user sessions, traces, and events. • Contribute to frontend applications that visualize RUM data, enabling users to debug performance issues and understand user behavior. • Work on data modeling, indexing strategies, and query optimization to ensure low-latency, cost-efficient analytics at scale. • Collaborate closely with SDK engineers (browser and mobile) to ensure high-quality data ingestion and schema evolution. • Own projects end-to-end: from design and implementation to deployment, monitoring, and iteration. • Break down complex, ambiguous problems into incremental deliverables and iterate quickly based on feedback. • Ensure quality through testing, observability of your own systems, documentation, and smooth upgrade paths. • Collaborate cross-functionally with backend, frontend, product, and solutions engineering to deliver cohesive observability workflows. • Support teammates, participate in technical design
