• Architect, deploy, and configure Arkime clusters, capture nodes, viewer nodes, and storage subsystems
• Design packet capture strategies aligned to network topology, mission requirements, and Zero Trust monitoring needs
• Develop and automate deployment workflows using scripts, orchestration tools, and configuration management
• Integrate Arkime with SIEM, SOAR, EDR, and threat intel platforms to enrich detection and investigation workflows
• Conduct regular tuning of parsers, views, tags, and sessions to support detection engineering and threat hunting
• Perform version upgrades, patching, configuration changes, data lifecycle management, and log retention optimization
• Align Arkime data capture with Zero Trust Architecture (ZTA) telemetry requirements
• Support development of visibility baselines, identity‑aware policies, and segmentation enforcement strategies
• Work with network engineering, cloud engineering, and security operations to ensure end‑to‑end telemetry coverage
• Develop dashboards, queries, workflows, and documentation for SOC, detection engineers, and incident responders
• Provide training, playbooks, and technical expertise to internal engineering and operations teams

• 5+ years of experience in cybersecurity, network security engineering, or security operations
• Strong background in packet analysis, PCAP management, DPI technologies, and network protocols (TCP/IP, DNS, TLS, HTTP, etc.)
• Familiarity with Suricata, Zeek, or other packet/flow analysis platforms
• Experience engineering within a Zero Trust Architecture (ZTA), including segmentation, continuous verification, and identity‑centric access
• Proficiency with Linux systems administration, containers, and distributed systems
• Experience leveraging SIEM/SOAR platforms and integrating packet telemetry with detection workflows
• Familiarity with automation tools (Ansible, Terraform, scripts) and infrastructure‑as‑code concepts
• Active TS/SCI clearance; willingness to take a polygraph exam
• Associate's degree and 5+ years of experience supporting IT projects and activities, Bachelor's degree and 3+ years of experience, or Master's degree and 1+ year of experience. Years of experience may be accepted in lieu of degree.
• DoD 8570.01‑M Information Assurance Technician (IAT) Level II Certification, including Security+, CCNA‑Security, GSEC, SSCP, CySA+, GICSP, or CND Certification
• Ability to obtain a DoD 8570.01‑M Cybersecurity Service Provider – Infrastructure Support Certification, including CEH, CHFI, CFR, Cloud+, or CND certification within 30 days of start date

• Hands‑on experience implementing and maintaining Arkime/Moloch in production environments
• Experience with cloud networking and traffic inspection in AWS, Azure, or GCP
• Experience with Elastic Stack or similar search/index pipelines
• Background supporting regulated or high‑security environments (FedRAMP, DoD, IC, PCI, etc.)
• Security certifications (e.g., CISSP, GCIH, GCIA, GNFA, GCED)
• Strong analytical and problem‑solving skills
• Ability to translate technical findings into clear operational guidance
• Comfortable leading discussions with engineers, analysts, architects, and leadership
