We are looking for a Senior / Lead DevOps / Observability Engineer to lead the migration of the client's observability stack from New Relic and Datadog to Grafana, using technologies such as Prometheus, Loki, and Tempo. This is a hands-on role combining: - DevOps & platform engineering - deploying and configuring the new observability stack using AWS, Kubernetes, and Terraform. - Application instrumentation - modifying application code to add or adapt metrics, logs, and traces. - Migration & collaboration - rebuilding existing dashboards and alerts in Grafana and working with multiple engineering teams to ensure full monitoring coverage. We are looking for someone who is comfortable working across both infrastructure and application code and can independently drive a cross-team observability migration. Responsibilities: * Lead the migration of monitoring, alerting, and dashboards from New Relic and Datadog to Grafana. * Design and implement the target observability architecture (metrics, logs, traces) and the infrastructure-as-code (Terraform) needed to support it.



* Audit existing New Relic and Datadog dashboards, alerts, and integrations to build a complete migration inventory and ensure feature/coverage parity in Grafana. * Make application-level code changes across services to add, adjust, or replace instrumentation (metrics exporters, logging, tracing libraries) as needed for the new stack. * Work with AWS infrastructure, including EKS, Kubernetes, and Docker, to deploy and operate the new observability tooling. * Configure AWS networking and access as needed to support the observability platform (VPCs, security groups, IAM). * Contribute to CI/CD pipelines and deployment automation using GitHub Actions to support the rollout. * Collaborate with development, platform, and infrastructure teams to coordinate the cutover from New Relic/Datadog to Grafana with minimal disruption. * Identify and remediate any security issues (secrets, keys, dependencies) encountered
