## Description

· Platform Infrastructure & Systems Deployment: Architect, configure, rack/stack, install, and sustain bare-metal compute servers, storage arrays, and enterprise networking hardware supporting mission-critical cyber defense infrastructure.

· Containerization & Virtualization Orchestration: Deploy, configure, scale, and maintain containerized workloads (Docker) and virtual machines (VMware ESXi, KVM, and cloud environments), ensuring multi-tenant resource isolation, resilience, and automated recovery.

· Linux Administration & Hardening: Administer and troubleshoot enterprise Linux operating systems across diverse distributions (e.g., Red Hat Enterprise Linux, Rocky Linux, Ubuntu). Implement rigorous system hardening in strict accordance with DoD Security Technical Implementation Guides (STIGs).

· Automation & Scripting: Develop, test, and maintain robust Python and Bash automation scripts to orchestrate system configurations, streamline health diagnostics, automate platform patching, and execute repetitive operational workflows.

· Network Forensics & Sensor Infrastructure: Integrate, configure, tune, and sustain network traffic capture and packet inspection engines (such as Zeek, Suricata, and network taps/aggregators) across high-throughput mission network segments.

· Data Pipelines & Telemetry Management: Support large-scale telemetry ingestion, index management, and cluster health for data search platforms such as the Elastic Stack (Elasticsearch, Logstash, Kibana), ensuring uninterrupted data flow from distributed endpoints and network sensors.

· Cloud & API Systems Integration: Manage system-level API integrations across secure cloud components and third-party cyber tooling; build connectors and data routing scripts to ensure reliable telemetry delivery to analytic engines.

· Performance Monitoring & Capacity Planning: Continuously monitor platform resource utilization, memory/CPU bottlenecks, I/O performance, and network throughput; formulate proactive capacity scaling recommendations.

· Cross-Functional Systems Collaboration: Collaborate closely with cyber defense operators, SOC analysts, and engineering teams to translate threat detection workflows and ATT&CK-aligned requirements into high-performing, resilient platform specifications.

· Technical Documentation & Accreditation: Author and update comprehensive systems architecture blueprints, standard operating procedures (SOPs), data-flow diagrams, and technical artifacts required for DoD Authority to Operate (ATO) packages and lifecycle sustainment.
