Senior SRE Engineer (Observability Focus)

TL;DR

Senior SRE Engineer (Observability Focus): Own end-to-end observability by designing and operating the telemetry stack for production visibility across hybrid AWS and on-prem environments with an accent on metrics, logs, and traces at scale. Focus on building VictoriaMetrics/OpenSearch/OpenTelemetry pipelines, running Kafka-based telemetry transport, and delivering Grafana dashboards and alerting that engineers actually use.

What you will do

• Own the full observability stack: VictoriaMetrics (metrics), OpenSearch (logs), and OpenTelemetry (traces) from pipeline design to day-2 operations.
• Architect and operate VictoriaMetrics clusters, including vmagent scraping, remote write, vmalert rules, and cardinality control.
• Operate OpenSearch clusters with ISM, hot-warm-cold architecture, shard tuning, and ingest pipelines via Data Prepper.
• Build and maintain OpenTelemetry Collector pipelines (receivers/processors/exporters) and instrument services across Java, Python, and JS/TS.
• Run Kafka as the telemetry transport layer (topic design, partition strategy, consumer lag monitoring, throughput tuning).
• Build Grafana dashboards/alerting and improve sampling strategies, batching, and context propagation; contribute to incident response and post-mortems.

Requirements

• 6+ years in DevOps/SRE/platform engineering, including 2+ years focused on observability tooling at production scale.
• Hands-on VictoriaMetrics (or Prometheus) expertise: MetricsQL/PromQL, exporters, service discovery, remote write, downsampling, and retention management.
• Solid OpenSearch/Elasticsearch skills: cluster operations, Query DSL, ISM policies, and ingest pipeline design.
• Production experience with OpenTelemetry: Collector configuration, OTLP, context propagation, and instrumentation across multiple languages.
• Strong Kafka skills: producer/consumer patterns, consumer group management, Kafka Connect, Schema Registry, and JMX monitoring (Strimzi on Kubernetes is a plus).
• Working knowledge of Kubernetes (operators, Helm), Argo CD/GitOps, and Terraform/Ansible; scripting in Bash or Python for automation.
