- Utilize tools from Synopsys/Cadence and apply expertise in UVM-based verification flows
Basic Qualifications:
- Bachelor's in Electronics/Electrical Engineering (Master's preferred).
- 12+ years of digital design experience, with 5+ years focused on high-speed PCIe/CXL implementation.
- Proven expertise in RTL development, synthesis, and timing closure.
- Experience with front-end design, gate-level simulations, and design verification.
- Strong work ethic, ability to handle multiple tasks, and a proactive, customer-focused attitude.
Required Expertise:
- Hands-on experience with high-speed protocols like PCIe/CXL (Gen4+).
- Strong proficiency in System Verilog/Verilog and scripting (Python/Perl).
- Experience with block-level and full-chip design at advanced nodes (≤ 16nm).
- Silicon bring-up and post-silicon debug experience.
- Familiarity with Synopsys/Cadence tools and UVM-based design verification.
Preferred Experience:
- Knowledge of system-level design for Gen4/5/6 PCIe.
- Understanding of PCIe PHY, DFT, and floor planning.
- Experience with NIC, switch, or storage product development.
- Familiarity with working in design and verification workflows in a CI/CD environment.
