The Opportunity:
We're looking for a talented and driven Physical Design Engineer to execute critical aspects of our chip implementation flow. In this hands-on role, you will be responsible for driving the physical design of cutting-edge SoCs from floorplanning through signoff. You'll work closely with front-end design, verification, and other teams to deliver high-performance, power-efficient, and area-optimized silicon.

What You'll Do

• Own and drive block-level and top-level physical design through place and route (P&R).
• Develop and optimize floorplans for complex IP blocks and SoC integration.
• Implement and manage clock tree synthesis (CTS) and optimize clock distribution for performance and power.
• Perform detailed routing and analyze timing, signal integrity, and power integrity issues.
• Ensure physical design closure: Drive timing closure, power optimization, and DRC/LVS/ANT signoff.
• Collaborate closely with front-end design teams to ensure seamless RTL to GDS handoff.
• Contribute to and improve physical design flows, methodologies, and automation for better PPA and turnaround time.

What You Bring

• A Bachelor's or Master's degree in Electrical or Computer Engineering.
• 5+ years of hands-on experience in physical design, including recent experience with advanced node Tape Outs (e.g., 3nm, 2nm).
• Deep expertise in place and route using Cadence toolchain (Genus, Innovus, Tempus, Voltus).
• Strong understanding of STA (Static Timing Analysis) and timing closure methodologies.
• Solid understanding of clock tree synthesis, EM/IR drop analysis, DRC/LVS signoff, and ECO implementation.
• Strong scripting skills (TCL, Python, Perl, BASH) for flow automation and efficiency improvements.
• Excellent communication and teamwork skills – you thrive in a collaborative, fast-paced environment

Bonus Points

• Knowledge of RISC-V-based SoCs or datacenter-class CPU designs.
• Familiarity with hierarchical design methodologies.
• Experience with low-power design and multi-voltage domain implementation.
• Exposure to DFT insertion and ATPG flows.

If you're excited about pushing the boundaries of computing and working on truly innovative technology in a rewarding environment, we'd love to hear from you
