Technical Lead Physical Design Engineer

$140,000–$180,000 year

On-siteToronto, Ontario, Canada

Full TimeSenior LevelMediumSemiconductors

Job Summary

Drive timing closure from RTL through sign-off, ensuring robust timing across complex SoCs. Develop and validate SDC constraints, including MMMC setup, to enable accurate STA analysis. Define and manage I/O timing budgets across hierarchical designs while applying advanced sign-off methodologies at TSMC 7nm and below. Leverage ETM libraries for hierarchical timing analysis and correlation, balancing runtime and accuracy. Provide actionable timing feedback at both block and full-chip levels, including root cause analysis and ECO guidance. Manage large-scale multi-corner/multi-mode STA runs with automation and partner closely with design, implementation, and verification teams to drive timing convergence. This role is fully on-site and in-person.

Required Qualifications

  • Bachelor's in Electrical Engineering or Computer Science
  • ≥5 years of experience in timing analysis and sign-off for complex SoCs in Server, Storage, or Networking applications
  • Expertise in timing constraints, STA methodology, and timing closure at both block and full-chip level
  • Strong knowledge of synthesis, place-and-route, extraction, and equivalence checking flows in advanced nodes (7nm or below)
  • Proficiency with Cadence and/or Synopsys physical design/STA toolchains
  • Strong scripting ability (Tcl, Python, Perl)
  • Ability to work independently with strong prioritization and a professional, customer-focused mindset

Desired Qualifications

  • Master's
  • Familiarity with high-speed SERDES and Ethernet PHY timing challenges
  • Knowledge of ECO methodologies, DFT tools, and test coverage analysis
  • Experience working with IP vendors for both RTL and hard-macro integration
  • SystemVerilog/Verilog familiarity
