IT Senior Network Engineer
Position #: 126109

The Senior Network Engineer’s role is to ensure the on-going stability, integrity, functionality and evolution of the University of Maryland’s Cisco CUCM VoIP telephony, call center, collaboration and E911 systems and processes. In addition this position will provide engineering support for the UMD local area networks, external connectivity and network services.

The position is heavily involved with full life-cycle service planning and implementation, which includes developing plans for the network aspects of service strategy, service design, service transition, service operations and continual service improvement. This work is done in collaboration with the Principal Network Architect and other Network Engineering colleagues, as well as other stakeholders to gather and refine requirements, while also staying current with industry trends and vendor capabilities. This position requires strong analysis and planning skills in order to develop both high-level voice system, network and network-related service roadmaps as well as detailed implementation plans. Implementation plans include, but are not limited to service improvements and upgrades (both client facing and administrative), equipment upgrades/replacements, and general design, security, and architecture improvements. This position requires an extensive understanding of and experience with VoIP-based telephony, the SIP protocol and Cisco’s CUCM VoIP platform, and may require the development, deployment or integration of new voice services.

This position also involves the planning, design, and implementation of voice and network infrastructure projects. The Senior Network Engineer should be able to work both independently and as part of a team. Project management skills and experience are required. The Senior Network Engineer is expected to be the project manager/lead on a portion of the department’s projects. This includes meeting with the stakeholders, gathering requirements, pulling in resources within the team and outside in order to coordinate their efforts, create and present designs, oversee and effect the implementation of assigned projects, and handoff support to the Operations Organization.

Documentation is a critical component of this position. Design documents will contain diagrams, purpose statements, stakeholder requirements, test plans, required personnel and hardware resources, cost estimates and schedules. Other duties include managing network resources and assisting in the management of network management systems and other support systems. Presentation skills are required to present designs, market solutions to stakeholders, and to provide training to operations staff and medium sized groups (<50). This position requires the mentoring of junior personnel within the Division of IT. This can involve a considerable amount of effort and time training, shadowing, guiding, and reviewing colleagues’ work activities and products.
