Principal Member of Technical Staff Broadband Access Technologies

This position requires a candidate that is a technical expert in broadband Access technologies with a high level of expertise in Wireless technologies, OSS/EMS systems/integration, Software Defined Networking (SDN) and developing Access Transport Architectures, Requirements and User Stories for Software Development and Testing. The PMTS will work with multiple Network and IT architects to develop end to end solutions that integrate wireless and wireline network elements and the associated support systems. This position is focused on the Next Gen Fixed Wireless RAN and CPE elements and the supporting management systems. The candidate will serve as the team subject matter expert in the wireless area and work closely with other peers and workgroups that are experts in IP networking, home networking and CPE and IT systems. The candidate must possess excellent technical documentation and presentation skills.

Candidates for this position apply intensive and diversified knowledge of wireless technologies, software development/management, SDN/NFV technologies in the design of Fixed Access End to End Solutions. The PMTS will apply engineering principles and practices in broad areas of complex technical project work that requires an in-depth evaluation using advanced techniques, knowledge and expertise derived from a strong educational background and progressive experience. The PMTS develops Gold Standards, Engineering Guidelines and Network Technology Development Documentation (NDR), on next generation Fixed Wireless and Wireline technologies, Domain 2.0 technologies and platforms involving end-to-end IP broadband networks. These technologies and platforms include and are not limited to cell site Fronthaul and Backhaul, MIMO technology and techniques, Frequency Division Multiplexing (FDM), Carrier Aggregation, Time Division Duplex (TDD) and QoS solutions for hybrid wireline and wireless ETE solutions. Additional areas of focus are integration with existing transport and cloud networks along with key network services applications, such as GPS, Radius, DHCP, NTP and NMS systems or micro applications. The PMTS works directly with cross functional teams including team members from Product Management, Network Planning, AT&T Labs, Chief Security Office, Network Operations and IT teams to develop an Integrated Solution. A large portion of the job involves collaboration with internal AT&T experts and vendors and developing technical documents which define the architectures, technical requirements, Agile EPICS/User Stories for a given Product, network enhancement or project. The candidate may design and validate logic of the steps to introduce complex new technology into the network. The PMTS may also be developing transition strategies and plans to achieve the new architecture.
