• Drive end-to-end ownership of design modules from specification through RTL development, integration, and silicon bring-up.
• Design high-quality, synthesizable RTL using Verilog/System Verilog, ensuring optimal performance, power, area (PPA), and scalability.
• Develop complex data paths, control logic, finite state machines, arbitration mechanisms, and protocol engines.
• Design and implement solutions for high-speed interfaces and protocols, including CXL, PCIe, Ethernet, and AXI-based interconnects.
• Collaborate with Architecture teams to define microarchitecture and review functional specifications.
• Partner closely with Design Verification teams to develop verification strategies, debug design issues, and achieve functional closure.
• Work with Physical Design teams to resolve timing, power, congestion, and implementation challenges through RTL optimization.
• Support synthesis, lint, CDC/RDC, STA, DFT, and design sign-off activities.
• Participate in design reviews and ensure compliance with RTL coding guidelines and design best practices.
• Drive debug and resolution of RTL, integration, and post-silicon issues in collaboration with firmware, validation, and system engineering teams.

Required Qualifications

• Bachelor's or Master's degree in Electrical Engineering, Electronics Engineering, Computer Engineering, or a related field.
• 6–12 years of experience in digital design for complex semiconductor products.
• Strong expertise in Verilog/System Verilog RTL design.
• Experience with complete ASIC design cycles from microarchitecture through RTL implementation and silicon bring-up.
• Strong understanding of digital design fundamentals, computer architecture, and SoC integration.
• Experience with synthesis, lint, CDC/RDC, STA, and RTL sign-off methodologies.
• Excellent debugging and analytical skills.

Preferred Technical Skills

Experience in one or more of the following:

• Compute Express Link (CXL)
• PCI Express (PCIe)
• Ethernet MAC/PCS
• High-speed networking or connectivity IP
• AXI-based SoC architecture
• DMA engines
