  • Build and support integrations with cloud platforms, Service Graph Connectors, and custom REST/SOAP interfaces
  • Develop scripts and tooling to improve data quality, deduplication, orphan detection, link validation, and bulk remediation
  • Create reports and dashboards to monitor ITOM health, coverage, reconciliation, and service map freshness
  • Produce and maintain technical documentation such as runbooks, architectural decisions, and integration designs
  • Stay current on ServiceNow platform releases and recommend enhancements and automation opportunities

Knowledge and Experience
  • Bachelor's degree in Computer Science, Information Technology, or related field, or equivalent practical experience
  • 5+ years of combined experience in ServiceNow and infrastructure/systems
  • Working knowledge of ServiceNow, including CMDB navigation, reporting, dashboards, and basic platform configuration
  • Hands-on understanding of servers, networks, cloud resources, and terminal-based administration
  • Familiarity with protocol used for ServiceNow Discovery, such as SSH, WMI, SNMP, WinRM, and cloud APIs
  • Ability to troubleshoot discovery issues across both platform and infrastructure layers
  • Scripting experience in Python, JavaScript, PowerShell, or shell scripting
  • Experience with REST and SOAP API integrations and large data extracts
  • Strong written and verbal communication skills, including technical documentation and stakeholder communication
  • Ability to work independently and collaborate effectively across cross-functional teams

Preferred Knowledge and Experience
  • Deep ServiceNow ITOM expertise across hybrid cloud and on-premise environments
  • Strong knowledge of CMDB and CSDM data models, including IRE, identification and reconciliation rules, data source precedence, and CI hierarchy
