Employer Type
This Senior FPGA Developer role is critical for building the core Quantum Key Distribution system. The main responsibility is full ownership of the FPGA design, including architecture, implementation in SystemVerilog, and achieving timing closure for high-rate interfaces on AMD/Xilinx platforms. The developer must also collaborate closely with software and embedded teams to ensure reliable system integration and is expected to mentor junior engineers.
Key Responsibilities
Own the SystemVerilog RTL architecture and implementation for Artix-7 and Kintex UltraScale FPGAs used in the Quantum Key Distribution system.
Implement and integrate crucial hardware interfaces such as DDR3/DDR4 controllers, PCIe endpoints, and Ethernet/SFP paths, including evaluating and integrating third-party IP.
Manage XDC constraints, apply practical floorplanning, and ensure consistent timing closure across all operating corners.
Establish and maintain a professional verification environment using tools like ModelSim/Questa, self-checking testbenches, and Python/cocotb co-simulation.
Define clear register maps and interface contracts for system integration and collaborate closely with software and firmware teams.
Provide mentorship to a junior engineer and establish engineering discipline, style guides, and design documentation.
Required Skills
5+ years of experience in production FPGA development on AMD/Xilinx platforms.
Expertise in SystemVerilog RTL design.
Strong proficiency in XDC constraints, clock domain crossing (CDC) methodology, and achieving consistent timing closure.
Hands-on experience implementing high-speed interfaces like DDR3/DDR4, PCIe endpoints/DMA, and Ethernet/SFP.
Strong verification background using self-checking testbenches and proficiency with ModelSim/Questa simulation tools.
Experience with continuous integration (CI) for HDL, including scripted simulation, synthesis, and implementation using Tcl, Make, or Python.
Experience with system integration involving software/firmware (register maps, driver contracts, Hardware-in-the-Loop testing).
Nice-to-have Skills
Expertise in AXI4/AXI-Stream and DMA performance tuning.
Exposure to formal verification methods.
Scripting for automation (Python/Tcl) and experience with CI systems (GitHub Actions/Jenkins).
Familiarity with MicroBlaze/Zynq ecosystems and low-level firmware or C driver collaboration.
Proven delivery on Artix-7 and/or Kintex UltraScale using Vivado.
