With SiFive, the future of RISC-V has no limits.\nAt SiFive, we are always excited to connect with talented individuals, who are just as passionate about driving innovation and changing the world as we are.\nOur constant innovation and ongoing success is down to our amazing teams of incredibly talented people, who collaborate and support each other to come up with truly groundbreaking ideas and solutions. Solutions that will have a huge impact on people's lives; making the world a better place, one processor at a time.\nAre you ready?\nTo learn more about SiFive’s phenomenal success and to see why we have won theGSA’s prestigious Most Respected Private Company Award(for the fourth time!), check out ourwebsite andGlassdoor pages.\nJob Description:\nThe Role:\nAs 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.\nKey Responsibilities\nFlow Execution & Validation:Implement, validate, and maintain production-ready RTL-to-GDS recipes using Synopsys Fusion Compiler based on established methodology guidelines.\n\nBlock Ownership:Take end-to-end implementation ownership of medium-sized CPU sub-blocks, driving them from RTL synthesis through to final GDS sign-off.\n\nPPA Optimization:Drive block-level PPA closure and contribute to hierarchical closure efforts, utilizing advanced techniques in timing-driven placement, CTS, and routing.\n\nML Deployment:Hands-on utilization of ML optimization tools (such as DSO.ai) to perform design space exploration and achieve optimal PPA targets.\n\nTechnical Execution & 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.\n\nCross-Functional Collaboration:Partner with IP teams (SRAM/Std Cell) and technical leads to analyze and model PPA impacts within your design blocks.\n\nAutomation & Scripting:Develop, enhance, and maintain robust Tcl/Python scripts to improve flow efficiency, ensuring repeatable and predictable results across design iterations.\n\nRequirements\nExperience:2+ years of hands-on experience in Physical Design/Methodology, with a strong track record in digital implementation.\n\nNode Knowledge:Solid experience with FinFET nodes (N5/N3); familiarity with N2/GAAFET challenges is a strong plus.\n\nTool Proficiency:Deep hands-on knowledge of the Synopsys digital implementation suite (Fusion Compiler, ICC2, PrimeTime, StarRC).\n\nDesign Understanding:Strong grasp of physical design concepts, including floorplanning, pin assignment, and timing budgeting within a hierarchical environment.\n\nAutomation Skills:High proficiency in Tcl and Python for flow customization, debugging, and data analysis.\n\nProblem Solving:Proven ability to analyze and resolve complex timing, power, and congestion issues in high-speed, high-density blocks.\n\nTeamwork:Excellent communication skills with a proven ability to collaborate effectively within a structured team environment and align with technical milestones.\n\n Additional Information:\nThis position requires a successful background and reference checks and satisfactory proof of your right to work in:\nIndiaAny offer of employment for this position is also contingent on the Company verifying that you are a authorized for access to export-controlled technology under applicable export control laws or, if you are not already authorized, our ability to successfully obtain any necessary export license(s) or other approvals.\nSiFive is an equal opportunity employer.
