About The Position

As a member of the Packet Core Network Commissioning team, the Technical Support Engineer III provides advanced technical engineering and support for the IP/MPLS core network. The team is focused on commissioning and implementing new technologies, network architectures, lifecycle solutions, and core network capacity, delivering high-quality and supportable engineering solutions that accelerate the evolution of the network. The team provides advanced technical and engineering support to Packet Architecture, Packet Engineering, and Reliability Engineering in support of core network commissioning, implementation, network evolution, and lifecycle activities. This role applies advanced IP/MPLS engineering knowledge to commission, implement, validate, troubleshoot, and optimize carrier-class network infrastructure. The role works directly with network equipment and software vendors at the Technical Assistance Center (TAC) level to address complex technical challenges and support the implementation of approved network changes and lifecycle solutions. The role supports network deployments, migrations, integrations, upgrades, configuration changes, troubleshooting, and special engineering projects while providing the ongoing technical care required to maintain the IP/MPLS core network. The role also supports the continued evolution of Network as a Service (NaaS) and software-driven network operations through automation, APIs, server and application infrastructure, and integrated engineering workflows.

Strong troubleshooting skills with demonstrated ability to isolate complex network, hardware, software, configuration, and interoperability challenges and drive them through resolution, including direct engagement with vendor TAC organizations.
Experience with network software lifecycle management, including software transfer, installation, upgrades, rollback, and troubleshooting.
Working knowledge of Linux-based systems and server environments, including common system and troubleshooting utilities.
Ability to develop, review, and execute advanced Methods of Procedure (MOPs) and use scripts and engineering tools to implement network changes safely.
Ability to support mandatory after-hours maintenance and network-change activities.
Excellent written and verbal communication skills, including the ability to communicate complex technical issues across Packet Engineering, Packet Architecture, Reliability Engineering, and vendor support teams.
Flexible and adaptable in a changing technical and operational environment.
Strong interpersonal and collaborative skills with the ability to work across technical teams, vendors, leadership, and other stakeholders.
Excellent judgment and organizational skills, with the ability to manage multiple priorities and meet deadlines.
Ability to work independently and productively with minimal supervision.

Nice To Haves

Experience with Nokia and Juniper routing platforms is preferred; experience with Cisco, Ciena, Adva, or other carrier-grade platforms is also valuable.
Familiarity with Network as a Service (NaaS), network automation, APIs, DevOps tools and practices, and software-driven network operations is preferred.
Experience supporting server/application stacks used by network engineering and automation platforms is preferred.
Scripting and automation experience with Bash and Python is strongly preferred.

Responsibilities
