Job description

  • Develop block-level micro-architecture for your assigned blocks, and contribute to interface and register definitions.
  • Design and implement front-end RTL blocks in SystemVerilog - datapath elements, the UCIe streaming/RDI adapter, elastic FIFOs, and supporting logic.
  • Integrate IP and support parameterization for configurability.
  • Write clean, lint-clean, CDC/RDC-clean RTL that follows the coding and quality standards.
  • Write block-level testbenches, sanity checks, and assertions (SVA) for your own blocks before handoff to DV.
  • Power- and timing-aware design - managing block activity, clock-gating, pipelining, and retiming; partner with the backend team on physical closure for your blocks.
  • Bring-up and debug across simulation and emulation / FPGA prototyping; support DV and silicon bring-up, including DFT/debug hooks in your blocks.
  • Collaborate with the architecture, modelling, DV, DFT, and backend teams as your blocks move through the flow.

Requirements

  • BS or MS in Electrical/Computer Engineering (or equivalent experience).
  • 3+ years of digital RTL design in SystemVerilog, with blocks taken from micro-architecture through to verification handoff.
  • Solid digital design fundamentals: pipelining, FSMs, FIFOs, clock-domain crossing, and streaming/bus interfaces (e.g., AXI).
  • Lint and CDC/RDC discipline and clean-RTL practices.
  • Power- and timing-aware design practices; comfort with synthesis and timing closure, working with the backend team.
  • Strong debug skills in simulation; scripting in Python, Perl, or TCL.

Preferred

  • High-speed datapath, SerDes-adjacent, or interface design exposure (UCIe, PCIe/CXL, or similar).
  • FEC/coding datapath familiarity (e.g., Reed-Solomon) and gray-code mapping.
  • Assertion-based verification (SVA) and familiarity with UVM block-level testbenches; emulation / FPGA prototyping experience.
  • Exposure to scale-up / scale-out interconnects or network switch / NIC / memory-controller datapaths.
  • Low-power / UPF and DFT (scan) concepts.
  • Optical transceiver, CPO, or linear-drive optics background; advanced-node (N5/N3/N2) design experience.
