Job Description: 
The Role:
As a Senior Physical Design Engineer , you will be responsible for executing and optimizing the RTL-to-GDS implementation flow for our high-performance CPU cores. In this role, you will take ownership of block-level implementation and contribute to advanced design recipes to drive PPA (Power, Performance, Area) closure on leading-edge N3/N2 process nodes. This position focuses on high-quality technical execution, hands-on design closure, and utilizing automated, ML-enhanced methodologies to hit aggressive frequency and power targets within a highly collaborative team environment.
Key Responsibilities
<ul><li>Flow Execution &amp; Validation: Implement, validate, and maintain production-ready RTL-to-GDS recipes using Synopsys Fusion Compiler based on established methodology guidelines.
</li><li>Block Ownership: Take end-to-end implementation ownership of medium-sized CPU sub-blocks, driving them from RTL synthesis through to final GDS sign-off.
</li><li>PPA Optimization: Drive block-level PPA closure and contribute to hierarchical closure efforts, utilizing advanced techniques in timing-driven placement, CTS, and routing.
</li><li>ML Deployment: Hands-on utilization of ML optimization tools (such as DSO.ai) to perform design space exploration and achieve optimal PPA targets.
</li><li>Technical Execution &amp; Troubleshooting: Identify, debug, and resolve flow and tool-related issues at the block level, collaborating closely with the wider methodology and core engineering teams to bypass bottlenecks.
</li><li>Cross-Functional Collaboration: Partner with IP teams (SRAM/Std Cell) and technical leads to analyze and model PPA impacts within your design blocks.
</li><li>Automation &amp; Scripting: Develop, enhance, and maintain robust Tcl/Python scripts to improve flow efficiency, ensuring repeatable and predictable results across design iterations.
</li></ul>Requirements
<ul><li>Experience: 4+ years of hands-on experience in Physical Design/Methodology, with a strong track record in digital implementation.
</li><li>Node Knowledge: Solid experience with FinFET nodes (N5/N3); familiarity with N2/GAAFET challenges is a strong plus.
</li><li>Tool Proficiency: Deep hands-on knowledge of the Synopsys digital implementation suite (Fusion Compiler, ICC2, PrimeTime, StarRC).
</li><li>Design Understanding: Strong grasp of physical design concepts, including floorplanning, pin assignment, and timing budgeting within a hierarchical environment.
</li><li>Automation Skills: High proficiency in Tcl and Python for flow customization, debugging, and data analysis.
</li><li>Problem Solving: Proven ability to analyze and resolve complex timing, power, and congestion issues in high-speed, high-density blocks.
</li><li>Teamwork: Excellent communication skills with a proven ability to collaborate effectively within a structured team environment and align with technical milestones.
</li></ul>Additional Information:
This position requires a successful background and reference checks and satisfactory proof of your right to work in:
