About the role
About ARSIEM Corporation
At ARSIEM Corporation we are committed to fostering a proven and trusted partnership with our government clients. We provide support to multiple agencies across the United States Government. ARSIEM has an experienced workforce of qualified professionals committed to providing the best possible support.
As demand increases, ARSIEM continues to provide reliable and cutting-edge technical solutions at the best value to our clients. That means a career packed with opportunities to grow and the ability to have an impact on every client you work with.
ARSIEM is looking for a JCDC Cyber Triage Analyst who serves as a frontline defender in the nation's cyber defense posture, performing initial analysis and triage of cyber threat reports, indicators of compromise (IOCs), and incident notifications submitted to the JCDC. This is not a developmental position. Analysts function similarly to a Tier 1/2 SOC analyst with enhanced threat intelligence responsibilities, and are expected to independently research cyber activity, rapidly assess and evaluate available information, develop defensible analytical conclusions, identify gaps, and recommend appropriate follow-on actions while maintaining strong coordination with government and private sector partners. This position will support one of our Government clients in Arlington, VA.

- Participate in shift handoffs and contribute to daily operational briefings
- Support development of triage playbooks and standard operating procedures
- Monitor emerging threat campaigns and trending adversary activity
- Provide feedback to submitters and partner organizations on ticket status and outcomes
Minimum Qualifications
- Bachelor’s degree in a technical discipline from an accredited college or university in Computer Science, Cybersecurity, Computer Engineering, or a related discipline; or a high school diploma and 4+ years of directly relevant technical experience.
