Everforth ECS is seeking a Sr. Security Analyst to work in our Remote office. This position is contingent upon additional funding.

As a leading managed cybersecurity services provider, ECS delivers highly tailored cybersecurity solutions aligned to each customer's mission needs. The Professional Services Team partners with customers to understand their environment, strengthen security posture, and deliver measurable outcomes across detection, response, and continuous improvement.

We are seeking a Security Analyst with strong Elastic SIEM experience and solid cybersecurity fundamentals who can investigate alerts, hunt threats, and help operationalize detection capabilities across network, cloud, and endpoint telemetry. This role requires analytical rigor, comfort working directly with customers, and the ability to operate with limited oversight in fast-paced environments.

Key Responsibilities

  • Network Monitoring & Intrusion Detection: Perform analysis using defense tools including IDS/IPS, firewalls, and host-based security systems.
  • SIEM Operations (Elastic SIEM): Use Elastic SIEM to correlate events, identify indicators of compromise, and produce actionable intelligence for response.
  • Threat Detection Engineering (Analyst-led): Implement and improve log-based and endpoint-based detection strategies; validate detections and recommend tuning based on outcomes.
  • Content Development: Develop and tune SIEM content such as detection rules, machine learning rules, dashboards, and visualizations aligned to customer requirements.
  • Activity Correlation: Correlate data across network, cloud, and endpoints to identify attacks and unauthorized actions.
  • Alert Management & Reporting: Triage alerts from SIEM and other sensors; document incidents with clear technical reporting and recommendations.
  • Threat Research: Investigate emerging threats and vulnerabilities to enhance detection and incident identification processes.
  • Phishing Analysis: Analyze phishing submissions and recommend appropriate response actions.
  • Incident Response Support: Support containment and mitigation activities; contribute to root cause analysis and corrective actions.
  • Automation & Integrations: Create or maintain scripts (Python/PowerShell) for investigation support, enrichment, and workflow automation; help integrate telemetry sources into Elastic as needed.
  • Customer Training & Enablement: Provide training to customer teams on SIEM usage, detection capabilities, investigation workflows, and security best practices to drive long-term operational success.
  • Operational Excellence: Contribute to documentation (runbooks, detection standards, triage playbooks) and continuous improvement of SOC workflows.

Salary Range: $90,000 - $120,000

About the Company

E

ECS Federal LLC

ECS was founded in 2001 by experienced IT professionals with a commitment to quality processes, people and performance. Led by our Chairman, Roy Kapani, and an experienced executive leadership team, ECS provides our customers with solutions and services that support their critical needs and further mission objectives. This commitment has paved the way for expansive growth, year over year.

ECS gained market share in 2011 in the Department of Defense and Federal spaces through both organic and acquisition growth. In May, ECS completed its first strategic acquisition with the purchase of OAK Management, Inc., a leading provider of marine environmental services, ship systems engineering, maritime consulting and platform acquisition management. The OAK acquisition kicked off ECS’ intention to add tactical acquisitions as a part of its long term strategy to supplement and expand upon organic growth and to build enterprise value. ECS closed out 2011 with the acquisition of Paradigm Technologies, Inc. The Paradigm transaction added approximately 200 employees to ECS’ existing 900+ employees. Paradigm also added new Defense clients for ECS, including the Missile Defense Agency, the Navy’s Program Executive Officer for Integrated Warfare Systems, the United States Marine Corps, and the U.S. Marshals Service.

In 2012, ECS completed the acquisition of iLuMinA Solutions, Inc. iLuMinA brings large-scale Enterprise Resource Planning (ERP) software implementation and infrastructure design and development to ECS’ expanding capabilities.

ECS will continue to invest in corporate infrastructure and quality processes as we grow and enhance our ability to offer professional excellence to both our customers and our employees.
