Role Overview

As a Senior Digital Design Engineer, you will design and integrate high-performance connectivity silicon for the next generation of AI infrastructure. You will contribute across architecture, micro-architecture, RTL implementation, synthesis, timing closure, and IP integration for PCIe and Ethernet controllers, bridges, switches, and related SerDes interfaces.

You will work with cross-functional teams to turn complex connectivity requirements into robust, production-ready designs. Your work will span block-level and full-chip development at advanced process nodes and help enable reliable, high-bandwidth connections among CPUs, GPUs, memory, storage, and networking devices in rack-scale AI systems. You will help improve product quality, accelerate time to market, and strengthen customer confidence in every release.

Key Responsibilities

  • Digital Architecture and RTL Implementation
  • Develop micro-architecture and implement synthesizable RTL for high-performance PCIe or Ethernet controllers, bridges, switches, and SerDes-related IP.
  • Translate architecture and protocol requirements into scalable designs using SystemVerilog and Verilog.
  • Own block-level and full-chip design deliverables from specification through implementation and GDS handoff.
  • Contribute to designs at advanced process nodes of 16 nm or smaller, including PCIe Gen 6/7, UALink, or UCI-based connectivity where applicable.
  • Integration, Timing, and Design Quality
  • Integrate controller, SerDes, processor, peripheral, and other IP while partnering with RTL, physical design, DFT, verification, and firmware teams.
  • Drive synthesis, timing analysis, timing closure, clock-domain crossing, lint, and design-quality reviews.
  • Support gate-level simulation, emulation, and pre-silicon and post-silicon design implementation activities.
  • Contribute to top-level integration, floor-planning discussions, PAD planning, and DFT implementation.
  • Cross-Functional Execution and Debug
  • Collaborate with verification and system teams to assess verification completeness, debug design issues, and close implementation gaps.
  • Partner with firmware and embedded software teams to define and validate hardware-software interfaces.
  • Use Synopsys and Cadence design and analysis tools, along with Python or Perl scripting, to improve design productivity and automation.
  • Communicate technical status, risks, and tradeoffs clearly while managing multiple priorities with appropriate ownership and urgency.

    • Basic Qualifications

  • Bachelor’s degree in Electrical Engineering, Electronics Engineering, or a related field.
  • 2 - 5 years of experience in digital design and implementation for complex SoC or silicon products.
  • Hands-on experience developing RTL in SystemVerilog or Verilog, including synthesis and timing closure.
  • Experience with PCIe or Ethernet controller, bridge, switch, PCS, PHY, or SerDes design and IP integration.
  • Experience with front-end design, gate-level simulation, clock-domain crossing, lint, or related design-quality methodologies.
  • Experience using Python or Perl to automate design, integration, or analysis workflows.
  • Ability to collaborate effectively across design, verification, physical design, DFT, firmware, and system teams.
  • Authorized to work in Canada.

    • Preferred Qualifications

  • Experience with PCIe or Ethernet SerDes controller or IP-level design, including PCIe Gen 6/7, UALink, or UCI.
  • Experience with block-level and full-chip implementation at advanced process nodes of 16 nm or smaller.
  • Knowledge of PAD design, DFT, floor planning, and top-level integration.
  • Experience developing NIC, switch, storage, or other high-performance connectivity products with embedded firmware interaction.
  • Familiarity with continuous integration and continuous delivery workflows for design and verification.
  • Experience with FPGA-based prototyping, emulation, or post-silicon debug.

    • Salary range is $139,500 to $155,000 CAD depending on experience, level, and business need. This role may be eligible for discretionary bonus, incentives and benefits.
