About the role:

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. This is an on-site role and will require presence in the office 5 days a week . No hybrid option is available.

What you'll do:

• Ownend-to-end physical design flow: synthesis support, floorplanning, 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

Required Qualifications:

• Bachelor's/Master's degree in Electrical Engineering or related field
• 8-12 years of experiencein ASIC physical design
• Proven experience infull-chip or large block implementation and tapeouts
• Strong expertise in:
• Floorplanning 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

Preferred Qualifications:

• Experience withlow-power design techniques (UPF/CPF)
• Knowledge ofEMIR analysis(e.g.,Ansys RedHawk-SC)
• Familiarity withmulti-voltage designs and power domains
• Experience withhigh-speed interfaces or complex SoCs (CPU/GPU/AI)
• Exposure toGLS and timing-related silicon debug
• Scripting expertise inPython/TCL

Compensation Range: $200,000-220,000 per year (California). This range represents the anticipated base pay for this role based in California; the final offer may vary based on qualifications, experience, and location.

• Medical, Dental, & Vision - 100% covered premiums
• Equity - Stock Options
