• Lead troubleshooting and root-cause analysis across log pipelines and SIEM integrations (including other SIEM platforms) as part of a shared 24/7 on-call rotation; implement preventative mechanisms through monitoring, runbooks, and automation.
• Build and enhance ingestion integrations and operational tooling using Python and regular expressions for parsing, validation, transformations, and schema evolution across standard and non-standard formats (e.g., JSON, Syslog, CEF, CSV/TSV).
• Develop monitoring and alerting aligned to platform SLOs/SLAs, improving completeness, timeliness, and quality while reducing incident recurrence and MTTR.
• Collaborate across teams to prioritize work, unblock partners, and continuously improve telemetry quality and platform performance.

• Demonstrated troubleshooting and root-cause analysis skills in production environments, including follow-through on preventative fixes (monitoring, runbooks, automation)
• Understanding of distributed systems fundamentals and common resilience patterns (timeouts, retries, idempotency)
• Experience migrating services or data flows between provider platforms (e.g., on-prem ↔ cloud)
• Willingness to participate in a shared 24/7 on-call rotation
