• Integrate and customize AMD/Xilinx FPGA reference designs, IP cores, board support packages, and development platforms.
• Develop and maintain Tcl scripts to automate Vivado project creation, design configuration, synthesis, implementation, bitstream generation, and hardware handoff workflows.
• Develop and integrate embedded Linux solutions using PetaLinux, including hardware handoff, boot configuration, device trees, board-support packages, and driver integration.
• Configure, integrate, and validate FPGA digital interfaces for high-speed converters, RF transceivers, memory, Ethernet, PCIe, JESD204, AXI, and other board-level peripherals.
• Support FPGA board bring-up, FPGA debugging, timing closure, interface troubleshooting, hardware validation, and laboratory integration activities.
• Collaborate with RF, software, systems, and hardware engineers to develop integrated system solutions.
• Support architecture development, technical trade studies, and future technology roadmaps for next-generation SDR, EW, sensing, communications, and PNT systems.
• Participate in customer meetings, technical reviews, demonstrations, and proposal activities.
• Contribute to innovative solutions for distributed sensing, remote operation, and advanced RF processing architectures.

• Bachelor’s degree from an ABET-accredited college or university in Electrical Engineering, Computer Engineering, Physics, or a related technical field.
• 8+ years of experience developing FPGA-based systems.
• Strong hands-on experience with AMD/Xilinx FPGA devices and Vivado development tools.
• Proficiency in VHDL and/or Verilog; SystemVerilog experience is a plus.
• Experience implementing digital signal-processing algorithms in FPGA architectures.
• Experience integrating AMD/Xilinx FPGA reference designs, IP cores, processor subsystems, board support packages, and high-speed digital interfaces.
• Experience writing Tcl scripts for Vivado project creation, build automation, implementation, and bitstream generation.
• Experience with PetaLinux, Vitis, or embedded Linux development for FPGA-based systems, including BSP, device-tree, boot, and driver configuration.
• Experience with software-defined radio platforms, digital RF systems, or real-time signal-processing systems.
• Familiarity with high-speed digital interfaces, data-movement architectures, and FPGA timing closure.
• Experience supporting board bring-up, FPGA debugging, hardware troubleshooting, and laboratory testing.
• Ability to work effectively in multidisciplinary engineering teams.
• U.S. Citizenship and ability to obtain and maintain a security clearance., * Experience with AMD/Xilinx RFSoC, Zynq UltraScale+, Versal, Kintex UltraScale, or similar FPGA architectures.
• Experience with high-speed data converters, JESD204B/C, DDR memory, PCIe, Ethernet, AXI, DMA, and high-throughput streaming architectures.
• Experience with FPGA simulation, verification, and debug tools such as Vivado Simulator, ModelSim/Questa, and Integrated Logic Analyzer.
• Knowledge of electronic warfare, SIGINT, radar, communications, or PNT systems.
• Experience with MATLAB, Python, C++, or embedded software development.
• Familiarity with fixed-point DSP design, FPGA resource optimization, and performance trade studies.
• Experience supporting government R&D, prototype development, or advanced technology programs.
• Active security clearance.
