Roles and Responsibilities

• Lead and perform configuration and development activities related to XSIAM data onboarding, ingestion, parsing, normalization, enrichment, and storage lifecycle management within the primary security analytics platform
• Onboard new client and internal data sources into the Managed Security SIEM environment through a variety of collection and transport methods, including API-based ingestion, syslog, agents, file-based collection, forwarders, cloud-native connectors, and other supported methods
• Develop, maintain, and tune parsers, field extractions, transformations, and normalization logic to ensure incoming telemetry is usable, consistent, and aligned to Managed Security standards
• Partner with Managed Security analysts, detection engineers, and client technical teams to define log source requirements for visibility, detection content, investigations, and reporting
• Establish and maintain data standards for source naming, field usage, tagging, metadata, categorization, and normalization across multiple client environments
• Support and optimize ingestion pipelines to ensure reliability, scale, and performance across diverse client log sources and varying data volumes
• Perform troubleshooting of data collection, transport, parser, and indexing issues, including validation of connectivity, format, mapping, field extraction, and downstream search usability
• Manage data tiering, storage allocation, retention strategies, and index lifecycle practices to ensure telemetry is retained appropriately and efficiently based on operational, contractual, and cost requirements
• Perform storage optimization and capacity planning activities within the SIEM platform to ensure ingestion remains within contracted scope while preserving the data needed for security operations and investigations
• Analyze data quality and data health across sources, including completeness, timeliness, parsing success, normalization coverage, duplication, and consistency
• Identify and implement opportunities to improve data pipeline efficiency, reduce noise, eliminate unnecessary data, and improve search and analytics performance
• Partner with SIEM, detection, and SOAR engineering resources to ensure standardized and enriched data supports dashboards, detections, automations, and incident workflows
• Build and maintain dashboards, reports, and health checks related to ingestion performance, parser quality, storage consumption, retention compliance, and onboarding progress
• Create tooling and scripts in Python or similar languages to automate onboarding checks, parser validation, data quality assessments, and platform administration tasks
• Assist with the development of processes and procedures to improve onboarding consistency, parser governance, data quality, and overall Managed Security functions
• Participate in client-facing security and technical meetings to support onboarding efforts, explain data requirements, review issues, and coordinate implementation activities
