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.
What you'll do:
- Own end-to-end physical design flow: synthesis support, floorplanning, placement, CTS, routing, and signoff
- Drive timing closure (setup/hold) across multiple PVT corners using advanced STA methodologies (OCV/POCV)
- Perform and debug DRC/LVS/EM/IR issues and drive clean signoff
- Work closely with RTL, architecture, and verification teams for design convergence
- Handle ECO flows, including late-stage timing and functional fixes
- Optimize designs for power, performance, and area (PPA)
- Integrate and validate hard macros (SRAMs, IOs, analog blocks)
- Support GLS, SDF generation, and debug timing-related issues
- Develop and enhance automation scripts (TCL/Python) for PD flows
- Collaborate with foundry/vendor teams during tapeout and signoff
Required Qualifications:
- Bachelor’s/Master’s degree in Electrical Engineering or related field
- 8–12 years of experience in ASIC physical design
- Proven experience in full-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
- Synopsys PrimeTime
- Mentor Calibre
- Experience with advanced nodes (7nm and below preferred)
- Strong debugging and problem-solving skills
Preferred Qualifications:
- Experience with low-power design techniques (UPF/CPF)
- Knowledge of EMIR analysis (e.g., Ansys RedHawk-SC)
- Familiarity with multi-voltage designs and power domains
- Experience with high-speed interfaces or complex SoCs (CPU/GPU/AI)
- Exposure to GLS and timing-related silicon debug
- Scripting expertise in Python/TCL
