Cyber Countermeasure Specialist; TN

Job Summary - $10,000 sign‑on bonus included (subject to a 12-month commitment)

Newberry Group is seeking an experienced, technically agile Cyber Countermeasure Specialist to support our customer’s defensive cyber operations team supporting the Joint Fires Network (JFN). Stationed inside secure SCIF environments at DISA Pacific (Ford Island, HI), this position plays a critical role in bridging detection analytics and active threat containment for the JFN Impact Level 7 (IL-7) environment and associated multi‑domain operational enclaves.

In this role, you will be responsible for the engineering, operational validation, deployment, and lifecycle maintenance of defensive countermeasures, detection signatures, sensor tuning, and containment workflows. Operating across up to 30 active operational nodes (including SD‑WAN transport fabrics and out‑of‑band management links), you will tune advanced network sensor grids (such as Corelight and Elastic Defend), author actionable threat containment playbooks within Atlassian JIRA, enforce strict Defense Intelligence Agency (DIA) TS/SCI spill and breach containment standards, and collaborate closely with Tier II NOC engineers (Solar Winds/Jira) and NIWC pipeline architects to neutralize adversarial activity across the JFN operational battlespace.

This is a full‑time onsite role in Ford Island, HI. Telework is not permitted.

Relocation expenses may be eligible for up to $10,000 reimbursement in addition to the sign‑on bonus.

$115,000 to $150,000 annually - depending on experience and position level.

• Sensor Tuning & Management: Configure, tune, and operationalize advanced boundary and enroute security sensors—including Corelight (Zeek‑based telemetry) and Elastic Defend
  —to maximize high‑fidelity detection while suppressing noise across JFN nodes.
• Custom Signature & Rule Development: Design, test, validate, and maintain custom intrusion detection rules, Zeek scripts, YARA rules, and Elastic SIEM detection logic targeting emerging exploit patterns, living‑off‑the‑land techniques, and lateral movement attempts.
• Palo Alto ATP & Pipeline Ingestion: Collaborate with NIWC data engineers to validate log ingestion pipelines (Logstash) from Palo Alto Advanced Threat Prevention (ATP), Prometheus, and endpoint monitors, ensuring sensor event logic triggers actionable containment mechanisms.
• Countermeasure Tracking & De-confliction: Track all deployed signatures and mitigation actions within JIRA; execute deliberate de‑confliction procedures with DISA and operational network authorities to prevent unintended disruption to operational fires data streams.
• Rapid Rollback & Operational Stability: Establish, document, and test rapid rollback mechanisms to immediately revert sensor configurations and containment rules if mission communications are impacted during crisis execution.

• Containment Playbook Development: Leverage Atlassian JIRA to design, automate, document, and maintain end‑to‑end standard operating procedures (SOPs) and execution runbooks for routine threat containment, node isolation and sensor re‑baselining.
• Incident Response Plan Operationalization: Support the drafting, maintenance, and technical execution of the JFN Incident Response Plan, ensuring rapid transition from alert triage to active containment.
• CSSP Defense Service Integration: Drive the technical countermeasure delivery for four of the seven DoD Cybersecurity Service Provider (CSSP) core functions during Phase I standup, expanding to full CSSP operational countermeasure capability during Phase II sustainment.
