About the role

Key responsibilities & impact

Build and evolve fullstack features for RUM, spanning backend services, APIs, storage systems, and frontend user experiences.
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 discussions and help shape the RUM roadmap.
