Senior Cyber Incident Analyst presso ECS

ECS is seeking a Senior Cyber Incident Analyst to work in our Fairfax, VA office.

ECS is seeking talented professionals to join our growing team in supporting the Joint Cyber Defense Collaborative (JCDC), CISA’s premier initiative for whole-of-nation cyber defense. JCDC brings together federal agencies, private sector leaders, and international partners to analyze emerging threats, share actionable intelligence, and coordinate strategic responses to protect critical infrastructure. 

Our team plays a vital role in enabling real-time collaboration, threat detection, and mitigation across sectors. We help shape the strategies and workflows that turn raw intelligence into decisive action—whether responding to active campaigns, developing joint defense plans, or strengthening national cyber resilience.

A passion for cybersecurity, continuous learning, and public service is vital. 

As a small team committed to radically improving government, every member directly shapes ECS’s direction and success. We take pride in our stewardship, holding deep responsibility for the solutions we develop.

The JCDC is CISA’s flagship initiative for uniting government, industry, and international partners to proactively defend against cyber threats.  Our ECS team is at the center of providing support to JCDC as they continue to plan, share, and respond to cyber threats in real time to support the greater cyber community and we are looking to grow our team supporting this critical mission.
