Everforth ECS is seeking a Senior Tier-3 Analyst 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 focuses on operational warfighting data and aims 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 Senior Tier-3 Analyst serves as the most advanced technical resource within the WDP User Support Desk, handling the most complex escalated incidents that cannot be resolved at lower support tiers and directing coordinated response activities across engineering, cybersecurity, data operations, and platform operations teams. This role carries responsibility for sustaining mission-critical capabilities across NIPRNet, SIPRNet, and JWICS environments while simultaneously elevating the technical proficiency of Tier-1 and Tier-2 support personnel.
Provides Tier 3 support for mission-critical analytics ecosystems across War Data Platform (WDP) Core Integration, Joint All-Domain operational environments, and multi-enclave cloud platforms supporting Combatant Command and Senior Executive Service decision-making activities.
Executes expert-level incident triage by reproducing complex faults, conducting deep-dive log reviews, analyzing infrastructure behavior trends, interpreting system telemetry, and validating distributed workflow dependencies using ServiceNow, Jira Service Management, Splunk, CloudWatch, Active Directory, and enterprise identity and access systems.
Oversees escalated service request queues, prioritizes mission-impacting incidents, and directs coordinated response activities across engineering, cybersecurity, data operations, and platform operations elements to restore full operational capability.
Conducts advanced troubleshooting for privileged access failures, cross-enclave onboarding, non-standard account provisioning, and specialized resource allocations spanning AWS GovCloud, Secret Region, and intelligence community cloud services.
Evaluates operational performance through mean time to restoration metrics, escalation frequency patterns, Tier-2 bypass indicators, and system stability signatures to recommend service improvements that elevate readiness and reinforce performance objectives.
Produces expert analyses, incident reports, workflow remediation plans, and knowledge artifacts supporting enterprise modernization and customer experience initiatives.
Trains Tier-1 and Tier-2 personnel on advanced diagnostic methods, structured troubleshooting frameworks, and enclave-specific operational procedures to strengthen team proficiency and accelerate restoration timelines across the full support continuum.
Performs other duties as assigned.

Hands-on expertise with enterprise IT service management and observability platforms including ServiceNow, Jira Service Management, Splunk, and CloudWatch, as well as identity and access management systems such as Active Directory and AWS IAM across classified and unclassified networks.
Demonstrated experience supporting or administering cloud environments in AWS GovCloud, AWS Secret Region, or intelligence community cloud services, including cross-enclave access provisioning, privileged account management, and non-standard onboarding workflows.
Proven ability to lead technical response activities, mentor junior and mid-level support personnel, and develop knowledge artifacts, diagnostic procedures, and training materials that improve team-wide performance and reduce escalation rates.
Strong problem-solving and decision-making capabilities, with a proven ability to weigh the relative costs and benefits of potential actions and identify the most appropriate solution.
