Job Description

As a Test Engineer, you will be part of the Regional National Development Team. You will work directly with our Regional Implementation teams, SWOPS (Switch Operations) Transport, and FOPS (Field Operations) to complete the integration, commissioning, and test turn-up of IP infrastructure to the highest standards. The Engineer will provide cost-effective support and implement solutions as part of the Magenta Build Initiative. You will be responsible for providing remote integration support on multiple backhaul solutions in a live production network deploying the following transport solutions: Dark Fiber, Lit Fiber Dedicated Ethernet (1 Gig-100 Gigabit Circuits). The position will require the Engineer to be directly involved in implementing backhaul solutions across multi-vendor platforms such as Nokia (formerly Alcatel-Lucent), Ericsson, Cisco, Ceragon, Dragon wave, and SIAE. In addition, the Engineer will remotely assist field installation teams in the commissioning/test and turn-up of new site builds as well as augments to optimize network performance. The engineer will be tasked with configuring network devices and triaging technical problems. Develop and enforce policies and procedures, properly organize projects, tasks, and provide the best possible end-user support experience. Use best practices in system installation, configuration, and monitoring to ensure minimum downtime and disruption to the network.
