Responsibilities
Be a technical leader on in-depth RF, Wireless, and RAN topics, provide technical guidance for next generation products and solutions, working closely with related architecture, design, engineering and deployments teams.
Lead 3GPP RAN or O-RAN Alliance standards participation and contribution
Lead prototype and proof-of-concept development on forward-looking products and solutions internally or in partnership with lead customers
File patents and/or author publications on innovative RF, Wireless, and RAN topics
Analyze customer needs as it relates 5G NR and RAN solutions and then communicate product requirements and communicate them to the product management and engineering teams
Work closely with business units and solutions teams on in-depth study of 5G
NR Radio Access Network design, configuration, implementation and optimization
Responsible for integration, validation and implementation of 5G NR RF and RAN functional, load, performance, optimization and assurance use case-based solutions.
Develop and communicate use case scenarios for Non-Stand Alone (4G-5G) and Stand Alone (5G) including beamforming, RF test and measurements, RAN optimization and assurance.
Educate the business unit, customers and partners on VIAVI’s 5G RF and RAN solutions
Present strategic thought-leadership to our customers and industry forums and standards bodies
Requirements
