What you'll be doing:

  • Developing complex RTL designs targeting both FPGA and ASIC

  • Translating system and algorithm requirements into RTL micro-architectures

  • Creating testbenches and validating designs on the latest FPGA platforms

  • Optimising designs for timing, throughput, hardware resources and power

  • Working across the full design lifecycle, from micro-architecture and RTL through to verification and physical implementation

  • Collaborating closely with Algorithm, System Architecture and Verification engineers

  • Producing high-quality design specifications and technical documentation

What we're looking for:
  • Expert-level Verilog / SystemVerilog

  • Strong commercial FPGA and/or ASIC design experience

  • Experience with synthesis and timing analysis

  • Knowledge of high-throughput data or signal-processing designs

  • Experience optimising timing and hardware resources

  • Strong knowledge of industry-standard EDA simulation and synthesis tools

  • Experience delivering complex, integrated digital designs

Additional experience with 5G, communications/DSP algorithms, UVM, AMBA, SystemC/C++, PCIe, JESD, Python or AMD/Xilinx FPGA technology would be highly advantageous.

If you're an experienced digital design engineer looking to work on challenging technology at the intersection of semiconductors, 5G and space communications, I'd be keen to speak with you.
