Everforth ECS is seeking a Performance Test 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 Performance Test Engineer designs, executes, and sustains the performance testing infrastructure that validates WDP Core Integration''s responsiveness, throughput, scalability, and resilience across the full software delivery lifecycle, directly supporting DoW mission-owner communities, Joint Staff analysts, Combatant Command elements, and Senior Executive Service leadership. This role ensures that WDP platform capabilities meet and sustain their performance commitments under both nominal and surge operational conditions by embedding automated performance validation into DevSecOps pipelines and continuous delivery workflows.

  • Develops and executes performance-testing activities supporting War Data Platform (WDP) Core Integration System software operations for Department of War missions, Joint Staff analysts, Combatant Command elements, and Senior Executive Service leadership.
  • Contributes to the War Data Platform (WDP) Core Integration System Test Plan by defining response-time, throughput, scalability, and quality-gate targets and embedding those targets as automated checks within CI/CD and DevSecOps pipelines.
  • Builds and maintains automated load-test scripts covering baseline, peak, stress, spike, and soak scenarios using JMeter, Locust, k6, Prometheus metrics, Grafana dashboards, and Elastic Stack telemetry.
  • Applies Infrastructure-as-Code tooling to provision isolated, production-like clusters with synthetic or masked mission data to support consistent and repeatable test execution.
  • Conducts scheduled and on-demand load, stress, and capacity tests and captures key performance indicators including percentile response times, transactions per second, CPU, memory, storage, and network utilization.
  • Correlates performance data with application logs, infrastructure traces, and deployment events to identify bottlenecks, performance regressions, and configuration issues.
  • Collaborates with development, operations, and security teams to validate fixes, refine test scenarios, and update performance baselines.
  • Produces performance-test artifacts including automated test pipelines, KPI dashboards, performance summaries, and release-readiness inputs supporting operational resilience, mission assurance, and sustained program value across the War Data Platform (WDP) Core Integration ecosystem.
  • Performs other duties as assigned.

About the Company

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.
