Security Operations Center (SOC) Analyst

Description

We are seeking, proactive defenders for a critical role safeguarding the nation's most sensitive digital landscapes. As a Security Operations Center (SOC) Analyst on our 24x7 front-line security operations team, you will be directly responsible for defending mission environments against the world's sophisticated and persistent cyber threats. This role demands exceptional critical thinking, a deep-seated adversary mindset, and a self-motivated drive to excel in a high-stakes mission.

Multiple Openings for SOC Analyst Level I & Level II

Primary Responsibilities:

• Conduct investigation and triage of security alerts from endpoints, IDS/IPS, NetFlow, and custom sensors to identify and neutralize threats within our mission spaces.

• Perform deep-dive analysis of extensive, highly-classified log files, pivoting between disparate datasets and correlating evidence to support complex incident investigations against nation-state actors.

• Produce detailed technical findings and reports for high-level stakeholders, documenting adversary tactics, techniques, and procedures (TTPs).

• Integrate and operationalize highly-classified threat intelligence feeds and Indicators of Compromise (IOCs) into security sensors and SIEM platforms.

• Collaborate closely with specialized incident response teams and ensure timely, precise communication of security incidents to mission partners.

Key Skillsets We Are Looking For:

• SOC Experience: You understand the operational flow, high tempo demands, and rigorous standards of a 24x7 Security Operations Center, particularly those operating at the highest classification levels.

• Critical Thinking & Adversary Mindset: You possess the ability to look beyond the surface of an alert to uncover the TTPs of advanced persistent threats (APTs). You excel at correlating disparate data points, analyzing raw packet data, and conducting deep-dive investigations of complex security events.

• Demonstrated Self-Motivation: You are a self-starter who takes active ownership of your professional development. Whether pursuing advanced certifications, researching emerging threat vectors, or mastering new tools, you drive your own growth to stay ahead of the adversary.

• Thrives on Change: The threat landscape and tactical priorities shift constantly. You demonstrate high operational adaptability, viewing unexpected shifts as opportunities to excel, and seamlessly pivot to adopt new processes, security tools, and analytical methodologies.

Shift & Operational Requirements:

• Mid Shift: 12:00 AM - 8:00 AM

• Flexibility: We highly value your work-life balance and make every effort to honor your shift preferences whenever possible. While final assignments must ensure critical program requirements are met, we strive to manage scheduling with a balanced approach that respects our team members' personal needs alongside mission readiness.
