5G Principal Engineer

RedRiver Systems L.L.C.
Richardson, Texas, United States

International manufacturer and supplier in the electronics industry is growing organically and through acquisition and seeking a 5G Architect. You will be involved in defining technical requirements and working toward continued architectural and quality improvement for 5G active antenna products. You will be a member of the Systems Engineering team where you will utilize your technical depth to develop detailed integrative designs as well as high-level conceptual approaches.

Relocation will be offered but 100% remote is not a possibility


  • Development of beamforming and MIMO radio system architectures and antenna array systems for existing 3G/4G wireless standards and developing 5G systems.
  • Condense high level standards and specifications into detailed requirements for sub-systems, blocks, and devices.
  • Conduct analysis and simulation of RF, MIMO, and beamforming behavior from baseband through the antenna and wireless link using Microwave Office, Keysight ADS, MatLab, and SimuLink.
  • Conduct chain analysis to optimize parametric distribution and RF impairment analysis to ensure system dynamic range and channel fidelity.
  • Perform link budget analysis to appropriately scale power amplifier and antenna characteristics.
  • Conduct simulation and analysis of system throughput for various channel conditions and hardware impairments.
  • Optimization of functional partitioning between DSP, mixed signal, and RF blocks.


  • Product development experience in 4G and 5G Massive MIMO
  • Experience in 5G Massive MIMO Radio Design and Systems Design
  • Experience on 5G Massive MIMO or Beamforming algorithm
  • Experience in sub-6 active/passive mMIMO Antenna systems including calibration algorithms.
  • Experience in active and adaptive beamforming RF systems.
  • Understanding of receiver and transmitter functional blocks and capabilities including antennas, power amplifiers, filters, duplexers, oscillators, frequency converters, modulators, and demodulators.
  • Wide range of experience in RF system phased array and/or beamforming simulation and analysis using Microwave Office, Keysight ADS, MatLab, and Simulink.
  • Experience in link budget analysis, chain analysis, EVM analysis, and throughput analysis.
  • Experience in analyzing high level system requirements to extract block level hardware and software level requirements.
  • Understanding of transmitter and receiver impairments including sources of thermal noise, phase noise, non-linearities, PIM, group delay, intermodulation, spurious and simulation of impairment impact.
  • Understanding of wireless receiver and transmitter architectures, antennas, and devices.
  • Knowledge of wireless infrastructure architectures and air interface standards including LTE and HSPA.
  • Skilled in thorough documentation of requirements and architectures and presentation of radio architecture concepts.
