Job Level

About the role

  • Own physical implementation for SoC blocks and/or top-level, including floor-planning, placement, CTS, routing, and physical optimization to meet PPA targets.
  • Drive timing closure (setup/hold) across multi-mode/multi-corner (MMMC) scenarios; partner with RTL, architecture, and STA/signoff to converge designs.
  • Collaborate with design and integration teams to ensure clean implementation of clocking/reset strategy, power architecture, and SoC integration requirements.
  • Integrate and implement complex IP (e.g., controllers, microcontrollers, NOC, interfaces, MBIST/DFT logic, buffers, PHY‑adjacent logic) with focus on robust physical integration and timing/power integrity.
  • Perform and/or coordinate physical signoff, including DRC/LVS, IR drop/EM, and timing signoff, addressing violations efficiently.
  • Partner with DFT teams to ensure scan/MBIST requirements are physically realizable and do not compromise PPA or schedule.
  • Work with packaging, assembly, test, probe, and manufacturing collaborators to ensure builds meet manufacturability and quality requirements.
  • Support tape-out execution (checklists, ECO flows, signoff reviews) and contribute to post-silicon debug by correlating silicon behavior with PD/STA/power analysis.
  • Identify flow gaps and improve productivity through scripting/automation and best-practice methodology development.

Requirements

  • Strong experience in SoC physical design implementation from netlist to GDSII on advanced nodes and complex designs.
  • Proficiency with industry EDA tools (e.g., Cadence Innovus/Tempus, Synopsys ICC2/PrimeTime, Siemens Calibre or equivalent).
  • Solid understanding of STA fundamentals, clocking, constraints (SDC), and common closure techniques (buffering, path shaping, useful skew, etc.).
  • Experience with power intent and power delivery considerations (e.g., UPF/CPF concepts, power grid planning, power gating implications).
  • Familiarity with physical verification/signoff concepts: DRC, LVS, ERC, parasitic extraction awareness, and signoff handoff quality.
  • Knowledge of IR/EM analysis, noise, coupling/crosstalk considerations, and mitigation strategies.
  • Strong scripting/automation skills using Python, TCL, Perl, and/or shell.
  • Experience with HBM / DRAM adjacent SoC designs, or memory-subsystem-heavy SoCs.
  • Bachelor’s or master’s degree in electrical engineering, Computer Engineering, or a related field.
  • Minimum 10 years of experience in a related field.
  • Proven ability to mentor and develop engineers early in their careers.
Benefits
  • choice of medical, dental and vision plans
  • benefit programs that help protect your income if you are unable to work due to illness or injury
  • paid family leave
  • robust paid time-off program
  • paid holidays
