Incident Manager II

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.

Responsibilities

• Perform initial triage and assessment of incoming cyber threat tickets, incident reports, and IOC submissions
• Analyze technical data including IP addresses, domain names, file hashes, network traffic patterns, and malware artifacts
• Determine threat severity, credibility, and potential impact to critical infrastructure sectors
• Enrich IOCs using threat intelligence platforms, open-source intelligence (OSINT), and government-exclusive resources
• Prepare concise triage reports with actionable recommendations for escalation or further analysis
• Route tickets to appropriate JCDC teams, CISA divisions, or interagency partners based on assessment findings
• Coordinate with sector-specific analysts and interagency liaisons to gather additional context
• Maintain accurate documentation in ticketing systems and knowledge management platforms
• 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.
