Senior Manager, Technical Support

Mavenir•Richardson, TX

About The Position

Mavenir is building the future of networks and pioneering advanced technology, focusing on the vision of a single, software-based automated network that runs on any cloud. As the industry's only end-to-end, cloud-native network software provider, Mavenir is transforming the way the world connects, accelerating software network transformation for 250+ Communications Service Providers in over 120 countries, which serve more than 50% of the world’s subscribers. Role Summary Mavenir builds 5G Open Radio Access Network (RAN) software, a type of telecom software that helps mobile operators within the telecommunications industry run their cell phone networks by connecting phone to the towers. The 5G Open RAN system is made up of: 1. Centralized Unit (CU) – higher-level processing, the part of the network that makes higher-level decisions, such as how to handle user data and connections; 2. Distributed Unit (DU) – lower-level, real-time processing that is closer to the cell towers and handles the real-time, fast decisions like which tower your phone should connect to; and 3. Management Nodes – the control and monitoring elements in the Network that operators use to monitor, configure, and troubleshoot the whole system. Key Responsibilities Mange a team of engineers and provide technical expertise. Ensure faster resolution of the field issue and very minimal customer impact. Install and integrate Mavenir 5G open RAN software (CU, DU & management nodes). Monitor the performance of the new software in the FOA markets and make sure there are no degradations in the KPIs. Plan for the nationwide roll out of the software and address issues during the execution. Triage new software performance and integration issues. Engage with the customer for new projects planning including Cloud migration/deployment. The Senior Manager, Technical Support manages and technically leads a team of engineers in the following activities: Install and set up this software, including any new release/s for any bug fixes or new features to ensure it runs properly Test the software in pilot markets (First Office Application (FOA)) to make sure the customer’s network performance is improved or at par with old software Monitor Key Performance Indicators (KPI) anomalies like Throughput, which includes download/upload speed, dropped calls, etc. Work with the customer on planning future projects such as migrating specific components of the Network into the cloud. The Senior Manager, Technical Support manages two employees: 1. Lead Engineer - II, Support Engineering 2. Technical Architect, RAN These employees are responsible for installing and setting up the software so it runs properly, testing the software in pilot markets (FOA) to make sure the customer’s network performance doesn’t worsen, monitor KPIs (speed, dropped calls, etc.), and work with the customer to plan future projects such as moving parts of the system into the cloud. The Senior Manager, Technical Support will work on specific client projects to support the bringing up and management of the 5G networks. This role works with 5G CU, 5G DU, xcal (to analyze Mobile device logs), Wireshark (to analyze network packet captures, i.e. snapshots of the data that makes up the network), and Couchbase Data base (to store documents, related to configuration of the management nodes). They will also work with 5G Open RAN systems, Amazon cloud, and VMWare cloud. 15% domestic travel to customer locations for site commissioning, sales workshops, and business meetings.
