• Strong background in communication theory and wideband digitization.
• 7+ years of hands-on FPGA design and development experience for complex digital systems.
• Strong proficiency in synthesizable RTL design.
• Experience with Vivado, Vitis, equivalent toolchains.
• Extensive high speed serial interface design – JESD204B/C, PCIe Gen3/4, Ethernet, Aurora, equivalent SERDES protocols.
• Ability to partition problems and to define block level HW architectures, and extensive knowledge of VHDL.
• Knowledge of real time implementation of complex DSP parallel processing structures.
• Work with System-on-Chip FPGA platforms, including embedded processors, DMA engines, memory-mapped control interfaces, Linux-based software stacks, and hardware/software partitioning.
• Strong lab debugging skills utilizing high speed oscilloscopes, signal generators, spectrum analyzers, logic analyzers, FPGA debug tools.

Nice To Haves

• Working knowledge of 5G, LTE related wireless PHY layer concepts including OFDM, FFT/iFFT processing, channel coding, synchronization and DFE processing.
• Experience with AMD RFSoC, Zynq Ultrascale+, Versal AI Core, Microchip Polarfire development.
• Experience with ECSS-E-ST-20-40C and ECSS-Q-ST-60 standards.

Responsibilities

• Research and design of fast and efficient hardware realizable DSP algorithms to implement functions such as filters, equalizers, timing/carrier recover loops, multi-rate structures (Polyphase Filter Banks), FFT processing engines
• Development and utilize models that provide real life stimulus for testing the developed algorithms including phase and gaussian noise, non-linear RF effects, Doppler, multipath and other channel impairments
• Perform simulation, verification, hardware bring-up, lab debugging, timing analysis, and performance validation using FPGA vendor tools and test equipment.
• Collaborate with systems, RF, software, hardware, and test engineering teams to define requirements, interfaces, verification plans, and system integration approaches.
• Design and integrate high-speed serial interfaces including JESD204B/C, PCIe, Ethernet, Aurora, SERDES, DDR memory interfaces, and AXI-based data paths.
• Develop high-performance RTL using VHDL, Verilog, and/or SystemVerilog, with emphasis on timing closure, resource efficiency, scalability, and maintainability.
• Develop and maintain design documentation, interface control documents, verification reports, timing summaries, utilization reports, and reusable IP documentation.
