Position Summary

Responsible for development of product requirements, feature requirements, systems, and performance analysis, conduct deep-dive customer sessions on 4G/5G Call processing related features and air interface technologies. Analyze the customer requirements, converting then into system requirements and capturing of detail design for the development team for all Samsung product features. Responsible for technical discussions on Samsung products/scheduler related features with several customer vertical organization including 4G/5G RAN Development groups and RAN performance groups. Author technical proposals, technical research and white papers, design documents, Operator network design, RFI/RFP, and Patent filings. Aid in product & feature performance analysis, evaluation of new product & SW releases and third-party product evaluation to build product synergies. Provides expert technical support in the pre-sales process and creates compelling technical and commercial solutions in order to help achieve the assigned sales goals and business objectives. Translate and communicate complex technical design considerations between the Samsung sales team and carriers' network business. Works closely with various support organizations, logistics, and cross-functional teams from SEA and Samsung HQ to achieve successful new product rollouts and developments. Accountable for leading field integration testing efforts (FFA/FIT/FSA) of all 4G/5G key features with customers, including test plan development, reviewing test plan with customers, driving cross-functional teams to execution, review of test results, issue identification, analysis and quality proofing until software acceptance is achieved. Responsible for Tier3 support, analyzing and troubleshooting scheduler related issues reported from customer labs, field sites and production network. Review and provide recommendations to improve LTE RAN network performance by evaluating and trending key KPIs, performing trials and providing optimization guidelines.

Role and Responsibilities

A core tenant of network engineering is ensuring the network infrastructure is robust and capable of supporting the software/applications being developed. The Engineer II, System Structure Design is accordingly responsible for designing network and performance features/systems that support Samsung's software product releases. Specifically, the Engineer II, System Structure Design must bridge the gap between new product development and design with Samsung's 4G/5G call processing (the entire sequence of events that occur from the initiation of a call to its completion) and air interface technologies (methods for wireless communication between a mobile device and a base station in cellular networks). Within this context, the Engineer II, System Structure Design must consider the software being employed, the capabilities and limitations of the cellular network, and the networks engineering processes and features that bridge the gap between software and the desired product. Additionally, the Engineer II, System Structure Design is responsible for designing products/scheduler related features for managing product release dates, setting start and end dates for product availability, production planning, and supply chain integration for 4G/5G Radio Access Network (RAN) Development groups and RAN performance groups.
