SoC Top RTL Integration Engineer

• Integrate multiple subsystems (CPU clusters, memory, accelerators, peripherals and third-party IP) into the SoC top-level RTL.
• Connect subsystems through interconnects and NoCs using protocols such as AXI, APB and CHI.
• Define and integrate the chip’s IOs, including connections to pads.
• Write and maintain SDC timing constraints for the integrated design, working with physical design teams.
• Run, debug and close lint, CDC and RDC checks at SoC top level.
• Integrate the top-level clock, reset and power infrastructure, and contribute to UPF power intent.
• Develop Python and C scripts and tests to automate integration flows and support bring-up.
• Work closely with architecture, verification, DFT and physical design teams to drive the SoC through to tape-out.

• Degree in Electrical Engineering, Electronic Engineering, Computer Engineering or a related field.
• 8+ years of experience in digital/SoC design.
• Strong hands-on RTL design experience (SystemVerilog/Verilog).
• Proven experience integrating multiple subsystems on large SoCs.
• Experience connecting subsystems through interconnects and/or NoCs, with solid knowledge of AXI and APB.
• Proven track record on one or more tape-outs.
• Hands-on experience with lint, CDC and RDC checks.
• Experience writing and managing SDC constraints and integrating chip IOs.
• Working knowledge of Python and C for scripting and automation (user level).
• Fluent English, written and spoken.

Nice to have

• Knowledge of clock, reset and power architectures.
• Experience with the CHI coherent interconnect protocol.
• Experience with UPF-based low-power design flows and pad ring integration.
