Who you are
- Proven experience designing and building observability platforms for large-scale, production infrastructure environments (not just consuming an existing setup — actually building one)
- Strong hands-on experience with metrics, logging, and distributed tracing tooling (e.g., Prometheus, Grafana, OpenTelemetry, Loki, Thanos/Cortex/Mimir, Elasticsearch/OpenSearch, Jaeger/Tempo, or equivalents)
- Experience with high-volume telemetry pipelines and the tradeoffs involved (cardinality, retention, cost, query latency)
- Strong software engineering skills in at least one language commonly used in this space (e.g., Go, Python, Rust)
- Experience with Kubernetes and cloud-native infrastructure
- Solid understanding of SLO/SLI/error-budget practices and alerting design that minimizes noise
- Comfortable working in a fast-moving environment where the platform is being built out alongside the infrastructure it's monitoring
- Strong communication skills — able to work directly with operations/service delivery teams to understand real incident-response needs,



not just technical specs
- Experience building observability for GPU/HPC infrastructure or other specialized, high-performance compute environments
- Experience with eBPF-based observability tooling
- Familiarity with AIOps/ML-based anomaly detection or automated triage systems
- Experience operating in a managed services or MSP context, where observability directly drives customer-facing SLAs
- Contributions to open-source observability projects
What the job involves
- Mirantis is building out our Neocloud service offering — managing large-scale infrastructure to a high SLA for customers running demanding compute workloads. As that offering scales, so does the volume and complexity of telemetry we need to collect, correlate, and act on
- We're looking for an Observability Platform Engineer to design and build the monitoring, logging, tracing, and alerting platform that our operations teams depend on to detect a
