We are seeking a highly skilled Network Engineer with strong experience in Cribl Stream/Edge/Cloud for managing, optimizing, and securing enterprise and mission-critical network environments. The Network Engineer will be responsible for designing, implementing, and supporting both traditional and software-defined networks while leveraging Cribl's observability pipelines to optimize data ingestion, routing, filtering, and enrichment across security and IT operations platforms.

This role requires an engineer who is equally comfortable in hands-on technical configuration, network troubleshooting, and observability/data flow management, while ensuring compliance with DoD cybersecurity frameworks.

• Implement data routing, transformation, masking, filtering, and enrichment policies within Cribl to support security, performance monitoring, and compliance use cases.
• Work with security operations (SOC), system administrators, and developers to ensure network and data flows are resilient, secure, and properly monitored.
• Manage and troubleshoot network performance issues, ensuring optimal availability and bandwidth utilization across hybrid environments (on-prem, cloud, tactical).
• Integrate Cribl with log forwarders, collectors, and agents (Syslog, Fluentd, Beats, Splunk UF/Heavy Forwarders, etc.).
• Perform packet capture and deep-dive analysis using Wireshark/tcpdump for troubleshooting and security investigations.
• Develop and maintain network diagrams, SOPs, and data flow documentation to support audits, assessments, and operational continuity.
• Ensure compliance with DoD RMF, DISA STIGs, NIST, and Zero Trust architectures.
• Support automation of network and data pipeline workflows using Python, Ansible, or scripting languages.

Required Qualifications

• Active DoD Secret clearance or higher.
• Bachelor's degree in Computer Science, IT, or related field (or equivalent experience).
• 5+ years of network engineering experience, with at least 1-2 years working with Cribl Stream/Edge/Cloud in production environments.
• Strong understanding of routing and switching (Cisco, Juniper, Palo Alto, Fortinet).
• Hands-on experience with Cribl observability pipelines, including data routing, transformation, and filtering.
• Familiarity with SIEM platforms (Splunk, ELK, QRadar) and how Cribl integrates with them.
• Expertise in TCP/IP, DNS, DHCP, VPNs, firewalls, and IDS/IPS.
• Experience with network monitoring and observ
