• Aid in the creation and review of requirements and develop solutions to meet design goals.
• Architect and design digital logic solutions for the latest AMD FPGA and SoC devices such as Zynq Ultrascale+ and Zynq Ultrascale+ RFSoCs.
• Design and implement HDL components for data acquisition, digital signal processing, command and control, external hardware interfaces, high-speed communication protocols such as Ethernet and PCIe, and more.
• Perform timing closure and create well-constrained, maintainable solutions that are easily extensible and employ an efficient use of resources.

• Integrate and test new designs in simulation, lab, and field environments.

• Use Python, TCL, and other scripting languages to automate and improve workflows.

• Strong interest in FPGA development, digital design, and embedded systems.
• Analytical problem-solving skills and attention to technical detail.
• Ability to collaborate effectively within a cross-functional engineering team.
• Curiosity and willingness to learn new tools, technologies, and technical concepts.
• Strong communication, organization, and time-management skills., * Bachelor’s degree in Electrical Engineering, Computer Engineering, or related field
• Proficiency with VHDL and/or Verilog to configure FPGAs and other embedded systems.
• Understanding of synchronous digital design, such as finite state machines, pipelining, combinatorial and sequential logic.
• Ability to create testbenches and use simulation to verify RTL behavior.
• Ability to travel 10%

Preferred Qualifications:

• Familiarity with AMD FPGAs, the Vivado design environment and their capabilities

• Experience writing thorough, self-checking testbenches for automated unit-tests

• Familiarity with source control, preferably Git.
• Excellent written and oral communication skills, coupled with the ability to listen, question, and understand stakeholder needs.

• Experience with or the willingness to learn about:

• Communication, Radar, and other Sensor systems
• Real-time control of RF front-end, memories, high-speed interfaces, and other hardware components
• Matlab, Simulink, HDL Coder, IP Integrator, and Xilinx System Generator
• Digital Signal Processing, Software Defined Radios, and RF System Design
