On any given day you will:

  • Tenaciously manage on premise and cloud-based DNS and DHCP environments to ensure they are operating at optimal levels through proactive monitoring/tuning

  • Implement new platforms/designs, code versions, and features to meet lifecycle management and business requirements
  • Contribute to enterprise strategy development/design standard development efforts
