Sr. Physical Design (ASIC) Engineer

Role: Senior ASIC PD Engineer ( 8+ Years experience )
Own the end-to-end RTL-to-GDSII implementation for complex IP/SoC subsystems and build the backend team that scales it. You’ll define the methodology, constraints, and quality metrics that the team shall adhere to. The team you lead will be responsible for synthesis, floor planning, P&R, clock tree synthesis, multi-corner STA, design for testability, and ECOs to achieve sign-off. You and your team will collaborate tightly not only with our RTL/digital team but also with our full-custom and full-custom layout team, integrating our full-custom design blocks into a digital-on-top mixed ASIC design. This is a hands-on technical leadership role, where you will not only set the flow and lead the team, but also personally de-risk and own the most challenging aspects of the design.
What you’ll do
Methodology: Define and maintain a modern RTL-to-GDS flow, including constraint strategy, libraries/PDKs, UPF/CPF, and sign-off checks.
Implementation: Run synthesis, floorplan, partitioning, P&R, CTS, routing, extraction, and closure.
PPA & quality: Create predictable PPA targets and tracking, lead timing/power ECOs; correlate pre/post-layout timing
Integration: Integrate custom macros, SRAMs, and I/O, manage clocking strategy, CDC, and hierarchical/hard-macro integration with LEF.
Low power: Own power intent (UPF/CPF), isolation/retention strategies, level shifting, and power-aware STA/simulation.
DFT & test hooks: Partner with DFT on scan/MBIST insertion and test timing; ensure routes and constraints don’t compromise test coverage or bring-up.
Automation & CI: Industrialize the flow with Tcl/Python automation, reproducible configurations, metrics dashboards, and CI/CD for nightly builds and regression testing.
Foundry interface: Engage with foundries on PDK updates, waiver handling, antenna/density rules, and reliability guidance; maintain the flow of information.
Requirements
Deep expertise in one complete tool chain (Synopsys or Cadence)
Hands-on experience in power-optimization techniques, including glitch reduction and activity-based power correlation (VCD/SAIF).
Strong MCMM STA and timing-closure experience
Experience with grid planning, IR/EM analysis, and fixes. Proven floorplanning/partitioning and hierarchical integration (hard-macros, abstracts/LEF, feedthroughs, blockage strategy).
UPF/CPF know-how for multi-voltage, power-gated designs, including isolation/retention and power-aware STA and sim.
Scripting for automation (Tcl, Python) and version control (Git, Perforce, or similar)
Ability to work and lead the activities independently and assume responsibility for major decisions
Nice to have
DFT exposure (scan planning, test timing, MBIST integration) and formal equivalence workflows.
Package/board co-design awareness (bump/rail planning, SSO/PI, thermal assumptions).
Experience at advanced nodes (≤ 7 nm FinFET) with multi-patterning/EUV constraints and variability considerations.
Familiarity with sign-off for safety-/quality-critical markets (automotive-style reliability targets, waiver governance, documentation rigor).
