Senior Observability and Monitoring Engineer

Company: Tabby
Location: Serbia
Employment type: Full-time

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

Requirements

Must Have

• 4+ years in DevOps / SRE / Observability roles
• 3+ years running production workloads on Kubernetes
• Infrastructure as code with Terraform
• Solid Linux and networking fundamentals, with strong troubleshooting skills
• Hands-on experience with a public cloud (GCP preferred; AWS or Azure also welcome)
• Experience building or operating data pipelines or observability platforms at scale (logs, metrics, or traces)

Nice to Have

• OpenTelemetry (collectors, Grafana Alloy, instrumentation)
• Kafka and ClickHouse
• Hands-on experience with metrics and APM platforms (Prometheus, VictoriaMetrics, Mimir, etc.) and Grafana
• Elastic Stack (Elasticsearch, Logstash, Kibana, Beats, log shippers)
• Exposure to security monitoring / SIEM integration
• Service mesh (Istio)

Why Join Us

• Design and build the next-generation observability platform from the ground up
• Work on large-scale, multi-cloud environments with a strong focus on compliance, performance, and reliability
• Collaborate with experienced SRE, Platform, and Security teams
• Competitive compensation, remote work model, and strong career growth opportunities
