Senior Elastic Stack Data Integration Engineer IRES - SSFB/HSV

The Senior Elastic Stack Data Integration Engineer 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., * 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.

• 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.

• Demonstrated ability to work independently, drive pipeline architecture decisions, and mentor junior engineers.
• Strong documentation, workflow diagramming, and communication skills.
