About the role

What will you do at ECS Tech Inc?

Everforth ECS is seeking a Cloud Security Engineer to work in the National

Capital Region covering the Pentagon, Falls Church, and Fairfax. Please Note:

This position is contingent upon contract award.

The War Data Platform (WDP) is a key initiative within the U.S. Department of

War's (DoW) AI-First strategy introduced in early 2026. The WDP separates

business and financial data from operational warfighting data, aiming to

accelerate the deployment of artificial intelligence (AI) on the battlefield.

The WDP extends to Unclassified, Secret, and Top Secret environments, and

supports collaboration between Combatant Commands, Joint Staff directorates,

Senior Executive Service leaders, and operational analysts.

The Cloud Security Engineer delivers hands-on cloud security engineering and

cyber defense operations across WDP's classified and unclassified environments,

with a focus on patch management, continuous monitoring, and incident response

spanning NIPRNet, SIPRNet, and JWICS. This role is integral to sustaining the

security posture, authorization compliance, and operational readiness of WDP's

multi-enclave AWS cloud infrastructure in direct support of DoW mission-owner

communities and Joint Staff elements.

• Conducts patch management operations across War Data Platform (WDP) Core

Integration cloud enclaves by operating vulnerability scanning workflows,

identifying required updates, tracking patch applicability, and automating

deployment actions aligned with Department of War patching directives supporting

Splunk, Elastic clusters, and integrated SIEM pipelines to detect configuration

drift, unauthorized change activity, and misconfigurations affecting War Data

Platform (WDP) Core Integration readiness.

• Supports deployment and evaluation of incident response procedures by

executing data collection steps, performing event correlation, documenting

operational impact, and generating incident response metrics such as mean time

to detect, mean time to respond, containment intervals, and recovery validation

results.

• Contributes to incident triage by analyzing indicators of compromise,

correlating system logs, validating remediation actions, and preparing status

reporting for senior operational leaders.

• Participates in lessons learned reviews by identifying root causes, proposing

corrective actions, and incorporating process improvements into standardized

runbooks, intelligence feeds, and automated control mechanisms.

• Strengthens defensive posture across NIPRNet, SIPRNet, and JWICS environments

by maintaining operational continuity, supporting cyber readiness objectives,

and contributing to mission-aligned cloud security modernization efforts.

• Performs other duties as assigned.
