Our client is a leading European online car marketplace, connecting car buyers and sellers across the continent. The platform serves over 30 million monthly users and operates across 18 countries, making it one of the largest and most trusted digital marketplaces for vehicles in Europe.
About the role
We are looking for a hands-on Observability / SRE Engineer with strong AWS infrastructure and networking skills to lead a focused, time-boxed migration of the monitoring setup for one application from New Relic to Grafana. You will be embedded in the client's engineering team, while owning the migration end to end and working independently as the sole engineer on this scope.
This is a short-term engagement with a clear deliverable. We value someone who can ramp up quickly, use modern AI-assisted tooling to move faster, communicate proactively with the team, and leave behind a clean, well-documented monitoring setup.
Responsibilities
• Assess the existing New Relic monitoring setup for the in-scope application, including dashboards, alerts, SLIs/SLOs,
synthetic checks, and log and trace usage.
• Define the migration approach and map New Relic constructs to their Grafana-stack equivalents (Grafana, Prometheus, Loki, Tempo or similar).
• Rebuild dashboards and alert rules in Grafana, validating that coverage and alert quality match or improve on the current state. Instrument and configure the application and its AWS infrastructure (such as compute, containers, load balancers, and managed services) to send metrics, logs, and traces to the new platform, using OpenTelemetry where applicable.
• Set up and validate secure network connectivity between AWS workloads and the Grafana stack, including VPC routing, security groups, VPC endpoints or PrivateLink, and DNS, and troubleshoot connectivity and data-flow issues.
• Run the old and new monitoring in parallel, verify data accuracy, and manage a safe cutover with minimal risk to production visibility; int
