Grow, innovate, and generate progress: Harness your expertise to solve challenges and celebrate success!

Job Summary

JCS Solutions is seeking a Security Operations Center (SOC) Analyst supporting the Pentagon Reservation under the DISA Penetration Handling, Incident, System Health (PHISH) Support Services II program. This position supports a 24/7 SOC mission and requires availability for rotating shifts, including weekends, holidays, and inclement-weather operations. The position requires 60 percent onsite work at the Mark Center in Alexandria, Virginia, consistent with program and customer requirements.

The Security Operations Center (SOC) Analyst supports continuous monitoring, detection, analysis, escalation, mitigation, and response to cybersecurity events affecting customer networks, endpoints, servers, applications, cloud environments, and mission systems. The analyst uses security telemetry, threat intelligence, established analytic procedures, and operational tools to identify suspicious or malicious activity; investigate potential compromises; document findings; and coordinate response actions with senior analysts, incident responders, cyber engineers, system owners, and mission partners.

This role is an experienced technical individual-contributor position. The SOC Analyst works independently to achieve day-to-day operational objectives and may own defined projects or technical processes within the SOC. The analyst contributes to operational cybersecurity, infrastructure support, and mission-support activities; collaborates with internal subject-matter experts to resolve technical problems; and may provide peer support, coaching, or technical review for less-experienced personnel.
