    Come do your best work and live your best life as part of the ONEXILINX team!

    Xilinx is looking for a talented individual to join the DFE Technology team in the position of DSP Engineer. This team develops high performance and low cost digital front end (DFE) Radio designs for 5G base stations and DOCSIS RemotePHY applications with Xilinx's unique RFSoC and Versal products and influences future device architectures.

    As DSP Engineer, you will have the opportunity to work on DFE design, development and system testing, with a strong focus on Digital Pre-

    distortion (DPD) and Crest Factor Reduction (CFR) which are critical to Xilinx's growth in sub-6GHz and mmwave 5G and cable communications applications. Key Responsibilities

  • Responsible for design, optimization and testing of communication signal processing algorithms and its fixed precision implementation and test with Matlab, C / C++
  • Responsible for writing optimized code for VLIW / SIMD processors
  • Developing a rich set of library kernels for 5G DFE, Beamformer, general signal processing functions and BLAS
  • Work closely with tools and design teams in US, Europe and India offices
  • Candidate will participate in different phases of a project, including architecture, system design, coding, unit testing, integration and maintenance and customer support
  • Create support documentation (data sheets, user guides, application notes, etc.) signal processing kernel and library products.
  • Assist software / tools engineering (or other dependent organizations) during integration phase of projects, i.e. integration testing and / or software flow testing.
  • Qualification and Requirements

  • MSEE preferred
  • 3+ years of experience developing optimized latest digital radio solutions with DSP processors and / or SIMD and VLIW processor architectures
  • 3+ years' experience in coding and optimization of signal processing kernels and library for DSP processor or GPU (examples would include LTE-
  • A, adaptive systems, synchronization, control systems, OFDM, MIMO, spatial multiplexing, beamforming, digital IF processing etc).

  • Theoretical and practical knowledge of digital signal processing (DSP), including digital filters, FFTs, fixed-point implementation of DSP data paths, digital communications.
  • Fluent in C / C++, Matlab, hands-on experience in fixed-point C / C++, communications system design using fixed-pint arithmetic in C / C++ is a must.
  • Excellent written and verbal communication skills in English
  • Experience creating internal and / or customer facing detailed documentation
