Role Summary

Today we sell 3rd party products for radio to go with our 4G Cloud RAN. To expand our product portfolio, we will develop own high-end Massive MIMO radios for sub 6 GHz for our 5G cloud RAN based on Open Interfaces. Focus will be on advanced technology and product development together with customers. We will progress this as a start-up company in Mavenir and leverage the whole organization. If you would like to work for a startup with resources, this is it.

Key Responsibilities

• Responsible for micro-architecture design, optimization and testing of uplink and downlink beamforming building blocks as per the ORAN 7.2 CAT-B fronthaul specifications.
• Responsible for development of unit-test framework to validate the beamformer performance
• Responsible for requirements gathering from the DU (distributed unit) and CU (centralized unit) teams, and end-to-end beamfomer performance testing by taking into account the DU-PHY, fronthaul, the channel emulator and test/commercial UEs
• Lead designer of fixed precision implementation and validation
• Responsible for writing VHDL/Verilog and using tools to emulate system test conditions for beamformer functionality on ORAN split solutions
• Develop embedded FPGA solutions on next generation FPGAs from Xilinx and Altera
• HW board bring-up in the lab for new products and design
• Deep knowledge on performing validation of functionality with MATLAB/python/C/C++ based environment
• Owner and creator of beamformer processing requirements documentation, including micro-architecture design documents, test specifications, test reports and user guides
• Participates into system feature specifications creation from the radio development team
• Perform technical evaluations of major system enhancements and major new customer requirements
• Create detailed system level functional requirements and specifications
• Monitor standards body activities to and participate (if necessary) to influence the industry with innovative vision of the company
• Identify opportunities for innovation and market disruption.
• Provide active support and guidance for program management
• Provide support for PLM and pre-sales in RFI/RFQ cases
• Provide system level technical support in customer meetings
