Senior Elastic Stack Data Integration Engineer

Senior Elastic Stack Data Integration Engineer

At cb5, we are on a mission to find exceptional talent. Our tight-knit organization is led by five brothers, each technology leaders in their respective technical fields and driven to foster a culture of excellence through solidarity. We are seeking a Senior Elastic Stack Data Integration Engineer to serve as a member of a Service Infrastructure team. This team is on the front lines, shaping the systems that protect us from advanced threats.

We are looking for highly motivated, results-oriented professionals who thrive on solving complex technical challenges in a dynamic environment.

The Senior Elastic Stack Data Integration Engineer supports a DOD/DOW customer and will serve as the primary technical authority for designing, building, and maintaining data ingestion pipelines supporting Elastic SIEM. This role focuses on creating scalable, resilient Logstash architectures; developing advanced pipeline logic; normalizing, enriching, and transforming security telemetry; and ensuring reliable delivery of high-fidelity data to Elasticsearch.

This is a full-time position working onsite at a location in Colorado Springs, CO or Huntsville, AL, requiring less than 10% travel.

• Architect, build, and maintain Logstash pipelines to ingest and transform logs from diverse systems, including network devices, servers, cloud services, and security platforms.
• Implement parsing, grok patterns, JSON transformations, conditional routing, enrichment logic, and ECS mapping.
• Optimize pipeline performance, resiliency, and scalability (e.g., persistent queues, pipeline workers, memory tuning, load balancing).
• Ensure all ingested data aligns to ECS (Elastic Common Schema) or internal schema requirements.
• Implement data enrichment workflows (GeoIP, threat intel lookups, metadata injection).
• Validate data completeness, integrity, and fidelity across ingestion flows.
• Maintain and optimize Logstash clusters, including version management, scaling, tuning, and high-availability configurations.
• Manage integrations with Beats, Elastic Agent, Kafka, syslog endpoints, and custom data collectors.
• Monitor ingestion throughput, latency, and error rates; implement proactive alerting and troubleshooting processes.
• Create and maintain technical documentation, including pipeline diagrams, data flow maps, runbooks, and schema references.
• Establish enterprise standards for parsing, enrichment, normalization, and ingestion patterns.
• Support internal and external audits by documenting data handling flows and pipeline logic.
• Work closely with SIEM integration engineers to align pipelines with customer environments and logging requirements.
• Partner with detection engineering teams to ensure data supports analytic coverage and rule development.
• Collaborate with infrastructure and platform operations for deployment, scaling, and reliability engineering.

The successful candidate will have:

• Demonstrated ability to work independently, drive pipeline architecture decisions, and mentor junior engineers.
• Strong documentation, workflow diagramming, and communication skills.
• Deep command of Logstash architecture, patterns, and performance optimization.
• Mastery of parsing, enrichment, normalization, and ECS alignment.
• Strong understanding of network protocols, logging patterns, and telemetry generation from enterprise systems.
• Advanced troubleshooting skills across data ingestion, pipeline logic, and Elastic Stack processing layers.
• Capability to design scalable, HA ingestion workflows with clear operational boundaries.
• Ability to conduct data modeling, schema design, and transformation mapping.
• Effective at interfacing with multiple teams, gathering requirements, and aligning pipeline designs with SIEM analytics needs.
• Focused on reliability, maintainability, and observability across all pipeline components.
• Strong attention to detail and a disciplined approach to documentation, versioning, and configuration management.

• 5+ years of experience in log ingestion, data engineering, or SIEM pipeline development.
• 2+ years of experience in a lead or senior role, mentoring and guiding other team members.
