SIEM Analyst

We are seeking a highly skilled and innovative SIEM Analyst to join our team in the greater DMV area, supporting the Army National Guard.

Responsibilities

• Review complex SIEM events, logs, and alerts; correlate telemetry from network, endpoint, identity, and cloud sources to detect anomalous activity.
• Investigate incidents through multi‑source correlation, timeline reconstruction, enrichment with threat intelligence, and IOC validation.
• Build and update intermediate‑level correlation rules, alert logic, and detection filters to address evolving use cases and improve fidelity.
• Document triage results, maintain investigation records with analytic notes, and categorize incidents per escalation criteria.
• Support tuning by identifying systemic false positives, refining rule parameters, and proposing detection enhancements.
• Collaborate with SOC analysts, threat hunters, cybersecurity engineers, and incident responders to provide technical context and preliminary root‑cause assessments.
• Maintain SIEM dashboards and operational reporting: update visualizations, refine queries, and validate metric accuracy.
• Verify ingestion, parsing, and normalization of log sources; perform data‑quality checks and report visibility gaps for remediation.
• Apply detection playbooks and organizational policies to sustain continuous monitoring across all enclaves.
• Contribute to SIEM operations improvement by refining analytic workflows, updating documentation, and adopting new platform capabilities.
