Senior SRE Engineer (Observability Focus)

Own the full observability stack: metrics (VictoriaMetrics), logs (OpenSearch), and traces (OpenTelemetry) — from pipeline design to day-2 operations.

Architect and run VictoriaMetrics cluster topology (vmstorage/vminsert/vmselect), including vmagent scraping, remote write configuration, vmalert rules, and cardinality control.

Operate OpenSearch clusters: index lifecycle management (ISM), hot-warm-cold architecture, shard tuning, and ingest pipelines via Data Prepper.

Build and maintain OTEL Collector pipelines — receivers, processors, exporters — and instrument services across Java, Python, and JS/TS stacks (auto and manual).

Run Kafka as the telemetry transport layer (OTEL Collector → Kafka → backends), including topic design, partition strategy, consumer group lag monitoring, and throughput tuning for high-volume telemetry.

Manage log shipping infrastructure using Fluent Bit, Vector, or Fluentd; define structured logging standards and field normalization across services.

Build Grafana dashboards and alerting that engineers actually use — clear, actionable, with well-structured variables and thresholds.

Work with platform and application teams to improve sampling strategies (head/tail), batching, and context propagation across distributed services.

Contribute to incident response, post-mortems, and reliability improvements driven by observability signals.

Mentor engineers on observability practices, tooling, and structured logging standards.
