About The Position

ARSIEM Corporation is seeking an Incident Manager II to support a government client in Arlington, Virginia. The posting describes the work as a JCDC Cyber Triage Analyst role and characterizes it as a frontline cyber defense position, not a developmental position. The analyst performs initial analysis and triage of cyber threat reports, indicators of compromise (IOCs), and incident notifications submitted to the JCDC, working similarly to a Tier 1/2 SOC analyst with enhanced threat intelligence responsibilities. Analysts are expected to independently research cyber activity, assess available information, develop defensible conclusions, identify information gaps, recommend follow-on actions, and coordinate with government and private-sector partners. The position requires an active TS/SCI clearance and the ability to obtain Department of Homeland Security (DHS) Entry on Duty (EOD) Suitability. The company describes its work as supporting government clients and agencies across the United States and highlights opportunities to grow and make an impact for clients.

  • Demonstrated experience recognizing and categorizing types of vulnerabilities and associated attacks.
  • Knowledge of Computer Network Defense policies, procedures, and regulations.
  • Knowledge of different operational threat environments, including first-generation (script kiddies), second-generation (non-state-sponsored), and third-generation (nation-state-sponsored) threats.
  • Knowledge of system and application security threats and vulnerabilities, including buffer overflow, mobile code, cross-site scripting, PL/SQL and injections, race conditions, covert channel, replay, return-oriented attacks, and malicious code.
  • Experience with SIEM platforms, threat intelligence platforms (TIP), and ticketing systems.
  • Knowledge of critical infrastructure sectors and associated cyber risks.
  • Familiarity with DHS/CISA products and services.
  • Security+, CySA+, GCIH, GCIA, or similar certifications.

Responsibilities

  • Perform initial triage and assessment of incoming cyber threat tickets, incident reports, and IOC submissions.

  • 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.
