• Build and troubleshoot ingest pipelines, parsers, index templates, data streams, mappings, and Index Lifecycle Management policies for high-volume security telemetry.
• Monitor and tune cluster health, capacity, performance, availability, shard allocation, retention, snapshots, and recovery processes.
• Implement secure access and data protection controls, including TLS or mTLS, certificate management, CAC or enterprise identity integration, role-based access control, Kibana spaces, and data segregation.
• Develop and refine dashboards, detection rules, alerting, and threat-hunting content aligned to mission use cases and MITRE ATT&CK.
• Integrate Elastic with endpoint, network, vulnerability, identity, ticketing, and security automation technologies used by the Agency CSSP.
• Support deployment and troubleshooting in disconnected, air-gapped, and classified environments, including offline repositories and controlled software transfer processes.
• Participate in customer workshops, testing, dual-run validation, cutover, and post-migration optimization at Fort Belvoir and other approved locations.

• Two or more years of hands-on experience engineering or operating Elastic Stack environments, or equivalent experience demonstrating the ability to perform the responsibilities of this role.
• Practical experience with Elasticsearch cluster architecture, Kibana, Fleet, Elastic Agents, ingest pipelines, data lifecycle management, monitoring, and troubleshooting.
• Experience securing enterprise platforms with TLS, certificates, identity integration, role-based access, and logical data separation.
• Linux administration experience, preferably Red Hat Enterprise Linux, and working knowledge of platform tuning such as vm.max_map_count, ulimits, memory, storage, and swap settings.
• Experience supporting DoD, federal, classified, or otherwise highly regulated environments and applying RMF, STIG, and NIST security controls.
• Experience supporting DoD CSSP or comparable SOC operations across multiple network enclaves.
• Ability to communicate technical issues clearly, work directly with customers, document solutions, and operate effectively during time-sensitive migration and cutover activities.
• Active Secret clearance and ability to maintain required access. Candidates supporting JWICS activities must be eligible for the applicable TS/SCI access.
