Troubleshoot deployment issues across multi-vendor NEM environments (vCCAP, RPD vendors) and complex customer IT environments

Support expansion deployments, including adding DAA capabilities to existing PathTrak/PNM systems and RCI deployments

Validate deployments post-installation and troubleshoot issues through to resolution, including simplified RCI expansion installs on existing PathTrak / PNM systems.

Augment Tier II/III TAC capacity by troubleshooting complex DAA issues escalated from Tier I.

Act as liaison to Engineering for issues requiring R&D involvement, ensuring escalations arrive well-vetted with all required logs and diagnostics, and owning customer-side actions during investigations.

Serve as the primary technical point of contact for a major strategic XPERTrak account, and communicate product issues and feedback directly back to the XPT business unit.

Develop process documents, methods of procedure, and work instructions for customers and internal teams.

Provide excellent customer service throughout the entire project and support lifecycle; ability to travel as required to support customer sites.
