IC/RTL Design Engineer
San Jose. Posted 4 months ago
The role
You will design and implement digital front-end RTL, including high-speed datapaths between UCIe and the optical front end. You will take blocks from micro-architecture through timing-aware RTL and block-level verification.
What you will do
- Develop block-level micro-architecture and contribute to interface and register definitions.
- Design and implement front-end RTL blocks in SystemVerilog.
- Integrate IP and support parameterization for configurability.
- Write clean, lint-clean, CDC/RDC-clean RTL following coding and quality standards.
- Write block-level testbenches, sanity checks, and assertions for blocks.
- Perform power- and timing-aware design including clock-gating, pipelining, and retiming.
- Partner with the backend team on physical closure for blocks.
- Bring-up and debug across simulation and emulation or FPGA prototyping.
- Support DV and silicon bring-up, including DFT/debug hooks.
- Collaborate with architecture, modelling, DV, DFT, and backend teams.
Required qualifications
- BS or MS in Electrical/Computer Engineering or equivalent experience.
- 3+ years of digital RTL design in SystemVerilog.
- 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.
Nice to have
- 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.
