• Keep abreast of industry trends and technologies to foster continuous improvement.
• Test and integrate new tools, particularly in observability and telemetry, to expand platform capabilities.
• Assess and incorporate the OpenTelemetry Collector to improve telemetry data collection and analysis.

Requirements

• Proven experience managing at least one observability stack (Thanos, Mimir, Cortex, Tempo, Loki, or Clickhouse), including configuration and optimization.
• Strong understanding of Kubernetes architecture and hands-on experience managing cluster resources.
• Experience writing and maintaining Helm charts, and deploying Kubernetes resources efficiently.
• Familiarity with continuous delivery and GitOps practices, including version control and CI/CD pipelines.
• Hands-on experience using agentic AI tools (e.g., GitHub Copilot, Claude Code, Cursor) to enhance daily engineering tasks.
• Expertise in containerization, orchestration, and optimizing Docker workloads.
• Bachelor’s degree in Computer Science, Information Technology, or equivalent experience.
• 5+ years of experience in platform engineering, site reliability engineering, or a related field.
• Experience managing large-scale infrastructures and observability platforms (e.g., Thanos, Mimir, Cortex, Tempo, Loki, Clickhouse).
• Excitement about managing over 20 TB of daily telemetry data from 10,000+ nodes (Linux hosts, Kubernetes clusters, VMs).

Nice to have

• Coding proficiency in Golang or a similar language.
• Contributions to open-source projects written in Golang or similar languages.
• Knowledge of the OpenTelemetry Collector or contributions to the project.
