Responsibilities
- 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.
