Principal Physical Design Engineer
San Jose, California, United States. Posted 7 months ago
The role
You will own the backend implementation of complex, high-performance SoCs. You will drive floorplan, timing, power, and signoff decisions for connectivity silicon.
What you will do
- Own the full RTL2GDS flow on advanced process nodes
- Drive block- and chip-level place & route strategy, congestion resolution, and routing convergence
- Architect clock tree synthesis and clocking topology
- Lead tapeout execution including final ECO closure, GDS handoff, and post-tapeout support
- Drive multi-mode multi-corner STA closure, low-power implementation, and IR/EM analysis
- Own physical verification and reliability signoff
- Define methodology for ECO flows, hierarchical timing, and full-chip signoff
- Partner with RTL, DFT, analog/mixed-signal, package, and CAD teams
- Establish and evolve physical design methodology, scripts, and flows
- Mentor engineers, drive design reviews, and represent Physical Design in program-level technical decisions
Required qualifications
- Bachelor's degree in Electrical Engineering, Computer Engineering, or related field
- 8+ years of physical design experience with multiple tapeouts on advanced process nodes (7nm or below)
- Deep expertise in synthesis, place & route, CTS, and timing closure using industry-standard tools (Synopsys Fusion Compiler / ICC2, Cadence Innovus, PrimeTime)
- Strong command of low-power design techniques (multi-Vt, power gating, DVFS, UPF)
- Proficiency in Tcl/Python scripting for flow automation
- Proven track record delivering high-frequency, high-complexity SoC blocks or full-chip implementations to production
Nice to have
- MS in Electrical Engineering or Computer Engineering
- Experience with high-speed SerDes-heavy designs, PCIe Gen 6/7, or UALink/UCIe-based connectivity SoCs
- Hands-on experience with hierarchical implementation and full-chip integration of large designs (>500M gates)
- Familiarity with EMIR, thermal, and package co-design considerations
- Experience mentoring senior engineers and driving methodology adoption across teams
