• Be Fearless: Unmute yourself. Test boundaries and get proven right.
• Remain Adaptable: Stay comfortable in a continuously changing world. If you’re wrong, concede and move on.
• Educate Your Ego: Selflessly collaborate towards our shared purpose.

As a Staff /
Senior Staff Physical Design Engineer , you will be responsible for driving full-chip or block-level physical implementation from netlist to GDSII. You will play a critical role in achieving timing, power, and area (PPA) targets while ensuring high-quality tapeouts.

• Ownend-to-end physical design flow: synthesis support, floor planning, placement, CTS, routing, and signoff
• Drivetiming closure(setup/hold) across multiple PVT corners using advanced STA methodologies (OCV/POCV)
• Perform and debugDRC/LVS/EM/IRissues and drive clean signoff
• Work closely with RTL, architecture, and verification teams fordesign convergence
• HandleECO flows, including late-stage timing and functional fixes
• Optimize designs forpower, performance, and area (PPA)
• Integrate and validatehard macros (SRAMs, IOs, analog blocks)
• SupportGLS, SDF generation, and debug timing-related issues
• Develop and enhanceautomation scripts(TCL/Python) for PD flows
• Collaborate with foundry/vendor teams duringtapeout and signoff

• Bachelor’s/Master’s degree in Electrical Engineering or related field
• 8–12 years of experience in ASIC physical design
• Proven experience infull-chip or large block implementation and tapeouts
• Strong expertise in:
• Floor planning and power planning
• Placement, CTS, routing, and physical verification
• Static Timing Analysis (STA) and timing closure
• Hands-on experience with industry-standard tools such as:
• Synopsys ICC2/Cadence Innovus
• Experience with advanced nodes (7nm and below preferred)
• Strong debugging and problem-solving skills

• Experience with low-power design techniques (UPF/CPF)
• Knowledge ofEMIR analysis(e.g.,Ansys Red Hawk-SC)
• Familiarity withmulti-voltage designs and power domains
• Experience with high-speed interfaces or complex SoCs (CPU/GPU/AI)
• Exposure toGLS and timing-related silicon debug
• Scripting expertise in Python/TCL
