Responsibilities

  • Build and maintain Splunk Apps and Technology Add-ons (TAs)
  • Onboard new data sources and normalize them to the Common Information Model (CIM)
  • Optimize data flow and ingestion using aggregation, filtering, and pipeline tuning
  • Configure notable event actions, action menus, and Adaptive Responses
  • Tune detections to cut noise and surface what matters, including risk-based alerting where applicable
  • Build dashboards that highlight anomalies, trends, and security and operational metrics
  • Support and optimize large distributed clustered Splunk environments (search heads, indexers, forwarders, deployment servers)
  • Partner with the client's security and SOC teams, debug complex integration and configuration issues
  • Document processes, procedures, and key engineering decisions
Requirements
  • Several years of hands-on Splunk experience, with real ES implementation, content development, and tuning
  • Strong SPL and regular expressions
  • Scripting in Python, Perl, or Bash
  • Solid grasp of CIM and data onboarding and normalization at scale
  • Experience supporting clustered Splunk environments in SOC or NOC settings
  • SIEM data modeling experience on a platform at scale
  • Proficiency in Linux, including editing and maintaining Splunk config files and apps
  • Comfortable working consultatively with client teams and explaining the why behind the work
  • Splunk certifications (Core Certified Consultant, ES Certified Admin, Architect) are a plus but not required
  • Demonstrated ES delivery experience carries more weight than paper
