We’re looking for a pragmatic, hands-on Data Engineer to join our Observability Squad and help build, run and scale our telemetry data platform based on the Grafana stack. In this role you’ll implement and maintain ingestion pipelines for metrics, logs and traces, instrument systems with OpenTelemetry, enable fast, reliable analytics for stakeholders, and collaborate closely with SREs, data architects and product teams to turn observability signals into actionable insights.

You’ll enjoy solving production-level data problems, tuning pipelines for performance and cost, and making observability data accessible and useful across the organization.

• Maintain and tune storage/query layer: Operate and optimize time-series and log stores (Prometheus, Loki, Tempo), including retention, compaction, indexing and cost optimization.
• Observability tooling & dashboards: Collaborate with analysts and product owners to create and maintain Grafana dashboards, alerts, and shared visualizations that provide clear operational and business insights.
• CI/CD and automation: Build tests, linting, deployments and observability for your pipelines using GitHub Actions (or similar), Terraform/Helm and IaC best practices.
• Data governance & security: Implement data access controls, masking where needed, and ensure compliance with data governance rules for telemetry data.
