Position: FPGA Engineer – Xilinx / RISC-V

Great Opportunity to work on cutting edge RISC-V and FPGA based compute platforms!

We are seeking an experienced FPGA Engineer with deep expertise in Xilinx FPGAs and hands on experience integrating and mapping SiFive RISC-V cores onto FPGA platforms. The ideal candidate will play a key role in prototyping, validating and optimizing SoC architectures for high performance and energy efficient computing platforms.

Responsibilities
  • Design, implement, and debug FPGA based systems using Xilinx FPGA platforms (Ultra Scale / Ultra Scale+ / Versal is preferred.
  • Map, integrate and validate SiFive RISC-V cores into FPGA designs.
  • Customize and configure RISC-V cores, interconnects, memory subsystems, and peripherals.
  • Develop and optimize FPGA designs using Vivado
    , Vitis
    , and related Xilinx tool chains.
  • Implement AXI-based interconnects and manage clocking, resets, and timing closure.
  • Perform functional verification, synthesis, place & route, and timing analysis.
  • Debug hardware and software interaction using simulation tools, logic analyzers, and on-chip debug features.
  • Collaborate with architecture, software and ASIC teams to transition FPGA prototypes to silicon.
  • Optimize designs for performance, power, and area (PPA).
  • Document architecture, design decisions, and validation results.
Qualifications
  • Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or related field.
  • At least 5 years of experience in FPGA design and development.
  • Strong hands on experience with Xilinx FPGAs and tool chains using Vivado, Vitis, SDK.
  • Proven experience mapping or integrating SiFive RISC-V cores into FPGA designs.
  • Strong proficiency in Verilog/System Verilog and/or VHDL.
  • Experience with AXI, AHB, and other standard SoC bus protocols.
  • Solid understanding of SoC architecture, memory controllers and peripherals.
  • Experience with FPGA based system bring up and debugging.
  • Familiarity with Linux or RTOS bring-up on RISC-V platforms.
  • Experience with RISC-V customization and extensions is a plus.
  • Knowledge of FPGA prototyping for ASIC development.
  • Experience with PCIe, Ethernet, DDR, HBM or high-speed interfaces is a plus.
  • Familiarity with UVM, simulation and formal verification.
  • Scripting experience with Python, Tcl, Bash for build and automation flows is a plus.
  • Exposure to power optimization and performance tuning on FPGA platforms.
