About this role

IC/RTL Design Engineer/ Front-End Engineer

About the role. You design and implement the digital front-end RTL at the heart of the chip - including the high-speed datapath that moves data between UCIe and the optical front end. Guided by the interface specs and coding standards, you take blocks from micro-architecture through clean, timing-aware RTL and block-level verification. It's a hands-on role with room to grow your scope as the team and the chip mature.

What you'll do

  • 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.

Required

  • 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.
