Details

Grafana Labs is hiring a Senior Fullstack Engineer to work on its Real User Monitoring (RUM) initiative. The role involves building systems that capture, store, query, and visualize high-volume user interaction data from browsers and mobile devices.

Grafana Labs is a 100% remote company. The RUM team works with OpenTelemetry and Grafana Cloud to deliver performant, cost-efficient, and developer-friendly observability experiences.

Responsibilities

Build and evolve fullstack RUM features spanning frontend experiences, backend services, APIs, and storage systems.
Design and implement systems that ingest, store, and query high-cardinality, high-volume telemetry data using columnar and analytical databases.
Develop performant query layers and APIs for real-time exploration of user sessions, traces, and events.
Build frontend applications that visualize RUM data and help users debug performance issues and understand user behavior.
Work on data modeling, indexing strategies, and query optimization for low-latency, cost-efficient analytics at scale.
Collaborate with browser and mobile SDK engineers on data ingestion and schema evolution.
Own projects end to end, including design, implementation, deployment, monitoring, and iteration.
Break down complex and ambiguous problems into incremental deliverables.
Ensure quality through testing, system observability, documentation, and smooth upgrade paths.
Collaborate with backend, frontend, product, and solutions engineering teams.
Support teammates, participate in technical design discussions, and help shape the RUM roadmap.
Use AI coding assistants for prototyping, test generation, refactoring, documentation, and incident follow-ups in accordance with security guidelines and code review standards.

Requirements

5+ years of fullstack engineering experience with strong frontend fundamentals.
Frontend experience with TypeScript and React.
Backend experience; Go is preferred.
Experience building or operating distributed systems in production, such as Kafka, WarpStream, Apache Pinot, ClickHouse, Cassandra, or Postgres.
Familiarity with cloud-native systems, including Docker, Kubernetes, AWS, GCP, or Azure.
Experience working with high-throughput, high-cardinality data such as logs, metrics, traces, and events.
Strong understanding of data modeling, query optimization, and performance tradeoffs.
Experience designing and building APIs and distributed services.
Experience building data-heavy user interfaces, including dashboards, query tools, or debugging interfaces.
Familiarity with observability concepts such as traces, logs, metrics, and/or OpenTelemetry.
Strong communication skills and the ability to work in a remote, distributed team.
Pragmatic, self-driven, and comfortable navigating ambiguity.
Customer-focused mindset with a passion for developer experience.

Bonus / Nice-to-Have

Experience with browser or mobile instrumentation, RUM SDKs, or telemetry collection.
Mobile development experience on iOS or Android, or familiarity with mobile performance and telemetry.
Contributions to OpenTelemetry or other observability open-source software.
Experience building developer-facing platforms or observability products.
Familiarity with session replay, sampling strategies, or user behavior analytics systems.
