About the Role
You will own end-to-end block and subsystem physical design, from synthesis through GDSII sign-off. You will drive timing and signoff closure, optimize power, performance, and area, create integration collateral, collaborate with RTL designers, and oversee outsourced physical-design deliverables.
Requirements
- 5–10+ years of physical-design experience
- Knowledge of RTL-synthesis-to-GDSII tools, flows, and methodology
- Experience with backend design and timing closure on 5 nm or smaller process nodes
- Experience with Cadence Innovus and Genus or Synopsys Fusion Compiler
- Experience with signoff tools including PrimeTime, Tempus, or Voltus
- Experience with UPF low-power methodology, power verification, synthesis, scan insertion, ATPG, formal verification, floorplanning, placement, CTS, routing, IR-drop analysis, and EM or antenna analysis
- Tcl, Python, or Perl scripting ability
Responsibilities
- Own end-to-end block and subsystem physical design from floorplanning through GDSII
- Drive timing closure, constraint development, STA debug, and ECO implementation
- Close signoff across EM, IR drop, RC extraction, and physical verification
- Generate abstracts, views, and timing budgets for hierarchical integration
- Provide physical-design feedback to RTL designers to improve PPA
- Improve block PPA and contribute learnings to the RTL-to-GDSII flow
- Supervise outsourced physical-design work and ensure delivered-block quality and closure
Benefits
- Medical, dental, and vision coverage with generous premium coverage
- USD 500 monthly credit for waiving medical benefits
- Wellness benefits for fitness and mental health
- Daily office lunch and dinner
- Unlimited compute budget subject to ROI justification
