We are forming a new Observability team responsible for the design, evolution, and operation of our company-wide monitoring, logging, and tracing platforms.

This role is a key part of our strategic shift from Datadog to a self-hosted observability stack fully compliant with local regulatory requirements.

Today, we operate multiple observability systems — our legacy stack based on Datadog (logs, metrics, APM, RUM, dashboards, and alerts), and our new Elastic Enterprise platform used for storing audit, access, application, and database logs required by regulators.

On top of Elastic, we've built SOC2 and SIEM integrations with external vendors.

You’ll be part of a small, highly technical team tasked with defining the future of observability at scale - designing, migrating, and maintaining the platforms that power visibility, compliance, and reliability across the organization.

Key Responsibilities Build and operate the new observability platform on Kubernetes: telemetry collectors, Kafka-based ingestion and processing pipelines, and the storage and query layer (ClickHouse, Mimir, Grafana)

Automate the platform's infrastructure with Terraform, Helm, and GitOps tools (FluxCD or ArgoCD)

Troubleshoot the platform end-to-end (Kubernetes, networking, pipelines) and plan its capacity, scaling, and cost

Support and gradually decommission Datadog integrations (logs, metrics, APM, RUM, dashboards, monitors)

Collaborate with SRE, DevOps, and Security teams to ensure observability compliance and integration with SOC 2 / SIEM

Define and maintain SLIs, SLOs, and error budgets, improving service reliability and visibility

Document architecture, data flows, and best practices
