The Enterprise Information Security (EIS) team is responsible for cybersecurity across our organization. We support our business and members by reducing risk, rapidly responding to threats, focusing on business resiliency and securing new acquisitions.

UHG operates one of the largest and most complex Splunk environments in the world - supporting a massive user base, 10,000+ applications, and data ingestion volumes exceeding hundreds of TB/day across on‑premises, cloud (AWS, Azure, GCP), and hybrid infrastructures. Our mission is to ensure this platform is not only operational and performant, but intelligently governed - delivering security intelligence that is trustworthy, searchable, and actionable at enterprise scale.

The Splunk Knowledge Manager is a critical, specialized role responsible for the governance, lifecycle management, and strategic oversight of all Splunk knowledge objects across the enterprise SIEM. This individual serves as the authoritative custodian of how data is classified, normalized, searched, and consumed - bridging platform engineering, detection engineering, and SOC operations. In a deployment of this scale, ungoverned knowledge objects directly drive alert fatigue, missed detections, redundant content, and degraded platform performance;

this role exists to prevent that entropy and ensure the SIEM delivers high‑fidelity security outcomes.

You’ll enjoy the flexibility to work remotely from anywhere within the U.S. as you take on some tough challenges. For all hires in the Minneapolis or Washington, D.C. area, you will be required to work in the office a minimum of four days per week.

• Knowledge Object Governance & Lifecycle Management
  - Provide centralized governance of all Splunk knowledge objects (saved/correlation searches, field extractions, tags, aliases, event types, lookups, macros, data models, workflow actions, KV store). Establish naming conventions, conduct audits to retire duplicate/orphaned content, maintain a registry/catalog, manage permissions, and lead CI/CD promotion pipelines (Git Hub, Git Hub Actions)
• CIM Normalization & Data Model Management
  - Serve as the enterprise CIM authority; design and maintain CIM‑compliant field mappings, data models, and acceleration strategies (TSIDX, tstats, summary indexing) across endpoint, network, identity, cloud, and application domains. Enforce source type/index taxonomy standards and maintain CIM-to-MITRE ATT&CK coverage matrices
• Knowledge Architecture & Standards Program
  - Own the enterprise Splunk knowledge architecture, publish and maintain the Knowledge Management Standards document, chair the Knowledge Governance Working Group, and define reusable content type templates for searches, dashboards, lookups, and macros
• Custom Automation & Data Quality Monitoring
  - Build automations to track data ingest, flow consistency, and drift from normalization standards, surfacing issues before they degrade detection efficacy
• Documentation, Training & Enablement
  - Maintain a comprehensive internal knowledge base (runbooks, SPL reference library, object catalogues), deliver training and office hours, mentor junior staff, partner with Splunk Professional Services, and produce executive reporting on knowledge base health
• Cross-Team Collaboration & Strategic Alignment
  - Serve as primary SME and liaison across Detection Engineering, SOC Operations, Platform Engineering, Compliance, and application teams - driving content quality, version migration planning, regulatory alignment (NYDFS, PCI DSS, HIPAA, SOX, NIST CSF), and AI/LLM‑ready knowledge…
