As a technical leader within the team, you will help maintain the integrity and security of enterprise-wide environments, guide the use of monitoring tools, and contribute to the development and tuning of countermeasures against emerging threats.

Responsibilities

• Work closely with Government counterparts to provide expert guidance within the Computer Network Defense Service Provider (CND-SP) area, ensuring alignment with mission needs and security objectives.
• Provide comprehensive CND reporting, including trends, responses, mitigations, analysis, and information dissemination to leadership and mission partners.

• Perform computer network incident detection and response activities to detect, correlate, identify, and characterize anomalous activity that may indicate threats to the enterprise.
• Monitor various security tools and applications, primarily Splunk and Elastic, for potential malicious activities and investigate associated alerts or indicators.
• Develop and recommend courses of action, including mitigation strategies, based on findings from security tools, logs, and network traffic analysis.
• Conduct analysis of low-level or "low and slow" events to identify unauthorized activity using exploratory problem-solving and self-learning techniques.
• Perform near real-time event triage and analysis, which may result in network traffic validation or the creation of incident reports for mission partners.
• Utilize formal monitoring policies and procedures, including DoD-approved network monitoring and traffic analysis tools, to identify suspicious, anomalous, or malicious network traffic on a 24/7/365 basis.
• Review and analyze available logs in a timely manner to detect intrusions and notify mission partners of relevant activity through formal reporting processes.
• Apply, develop, tune, and distribute or optimize new and existing countermeasures or guidance to prevent or mitigate potential cyber event impacts whenever possible.
• Perform detailed network traffic analysis using raw packet data, netflow, IDS, IPS, and custom sensor output to identify and understand security events.
• Configure and manage firewalls, IDS/IPS, and other security appliances to support Protect, Defend, Respond, and Sustain activities.
• Audit network traffic, harden devices, and implement security policies to enhance the overall security posture.
• Use command-line scripting (such as PERL, Python, and Shell) to automate tasks, streamline analysis, and improve operational efficiency.
• Support DOD-related projects or programs by providing cyber incident handling expertise and real-time analysis.
• Collaborate with other SOC analysts across multiple shifts to ensure continuous monitoring and consistent incident handling coverage.

Essential Skills

• At least 4 years of overall professional experience, preferably combined with a bachelors degree.
• Active Secret clearance, with an active Top Secret clearance preferred.

• Demonstrated experience monitoring IDS and computer defense appliances, specifically using tools such as Splunk and Elastic.
• Experience evaluating and interpreting packet captures and network traffic to identify security incidents.
• Proficiency with command-line scripting, particularly in PERL, Python, and/or Shell scripting, to automate operational and analytical tasks.
• Prior experience supporting Department of Defense-related projects or programs.
• Ability and willingness to work assigned shifts, including day, swing, or night schedules in a 24/7/365 SOC environment.
• Strong incident response, cyber security, and vulnerability assessment skills, including familiarity with SIEM-driven workflows.
• Possession of Security+ (or equivalent baseline security certification) in combination with a Top Secret clearance as a core requirement for the role.

Additional Skills and Qualifications

• Ability to obtain CYSA+ or CEH certification within 6 months of hire; holding these or other advanced cyber certifications at the time of hire is a strong plus.
• Experience working in a high-tempo Security Operations Center (SOC) or Cyber Defense environment supporting enterprise networks.
• Familiarity with DoD network monitoring and traffic analysis tools and formal monitoring policies and procedures.
• Experience conducting analysis of low-level, "low and slow" events to uncover stealthy or persistent threats.
• Strong analytical, problem-solving, and self-learning capabilities to investigate complex or ambiguous security events.
• Effective communication skills to clearly articulate findings, trends, and recommendations to leadership, peers, and mission partners.
• Ability to collaborate in a team environment and provide technical leadership or mentorship to other analysts.
• Comfort working with structured reporting processes and formal incident documentation for mission partners.
• Experience working with or within Cyber Security Service Provider (CSSP) or CND-SP environments is beneficial.
