Detection Engineer

Program Overview

About The Role

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

Responsibilities

• Develop and maintain detection logic across SIEM, IDS/IPS, endpoint, and OT/DCI monitoring platforms: correlation rules, signatures, and behavioral analytics.
• Translate threat intelligence, CDAP findings, CHAP results, and vulnerability data into detection use cases, dashboards, and alerting content.
• Test detection rules in lab and sample datasets to verify functionality, tune for false‑positive reduction, and validate operational readiness.
• Document detection logic, metadata, versioned content, and change histories to support operational tracking and auditability.
• Collaborate with SOC and NOSC analysts to tune alerts, refine rule logic, and validate detections against observed activity.
• Update runbooks, produce tuning notes, and support analysts during triage and validation workflows.
• Coordinate with data engineers to ensure ingestion, normalization, and field mappings for high‑value telemetry sources.
• Review telemetry quality, identify gaps in coverage, and report issues that affect detection visibility.
• Contribute to continuous improvement by iterating detection content, refining workflows, and adopting new defensive techniques.
