• Develop, deploy, and operate high-throughput telemetry pipelines, ensuring accurate and actionable monitoring across cloud environments.
• Collaborate with engineering and product teams to define and champion observability best practices
• Work with DevOps and development teams to automate collection, ingestion, and retention policies for logs, metrics, and traces
• Drive continuous improvement in system performance, stability, and reliability through effective observability
• Participate in on-call rotations, incident response, and root cause analysis to enhance monitoring and alerting capabilities.

Requirements

• 5+ years of engineering experience in cloud observability platforms, infrastructure, and telemetry systems
• Deep experience in alerting, notifications, and monitoring at scale
• Advanced expertise with ClickHouse, or similar high-performance analytical databases, for telemetry storage and querying
• Hands-on experience migrating telemetry/storage solutions (preferably from Cosmos DB to ClickHouse or equivalent)
• Solid understanding of telemetry pipelines, cloud-native monitoring, and best practices
• Experience with dashboarding and visualization tools (Grafana, Kibana, or similar)
• Strong scripting and automation skills (Python, Bash, Terraform or equivalent)
• Proven collaboration and communication skills across cross-functional teams.
