  • Strong problem-solving skills and ability to work in a fast-paced environment 
  • Excellent communication skills with both technical and non-technical stakeholders 

Preferred Qualifications

  • Experience with additional ServiceNow modules such as: ITOM, CSM, HRSD, SecOps, GRC 
  • Experience in federal or public sector environments
