Job description

We are looking for a Senior/Staff STA Engineer to lead full-chip timing signoff activities for cutting-edge SoCs at advanced technology nodes (5nm / 3nm / 2nm).

The candidate should possess deep expertise in MMMC timing closure, hierarchical timing budgeting, ECO convergence, and final tapeout signoff.

This role requires close collaboration with RTL, Physical Design, Clocking, to achieve timing closure for high-performance silicon.

Key Responsibilities

  • Own full-chip STA across all modes and PVT corners.
  • Drive MMMC timing closure and convergence.
  • Develop and maintain timing constraints and hierarchical timing budgets.
  • Analyze setup/hold violations and drive ECO closure.
  • Execute timing signoff using industry-standard tools.
  • Collaborate with Physical Design and Clock teams to improve timing QoR.
  • Debug complex timing issues at top-level integration.
  • Improve signoff methodologies for runtime and convergence efficiency.
  • Present timing closure status and risks to leadership teams.

Frequently asked questions

Q: What skills or qualities help someone succeed as a Physical Design Engineer?

A: To succeed as a Physical Design Engineer, key technical skills include proficiency in computer-aided design (CAD) software, such as SolidWorks or Autodesk Inventor, as well as expertise in finite element analysis (FEA) and computational fluid dynamics (CFD). Soft skills like effective communication, collaboration, and problem-solving abilities are also crucial, as Physical Design Engineers often work in cross-functional teams and must interpret complex data to inform design decisions. By combining technical expertise with strong interpersonal and analytical skills, Physical Design Engineers can drive innovation, optimize product performance, and contribute to the success of their organization.

Q: What is the career path for a Physical Design Engineer?

A: A Physical Design Engineer's career path typically begins with entry-level roles such as Design Engineer or Junior Physical Design Engineer, where they develop foundational skills in design automation, layout, and verification. As they gain experience, they progress to mid-level roles like Senior Physical Design Engineer or Design Lead, where they oversee design teams, mentor junior engineers, and contribute to design methodology improvements. Ultimately, senior Physical Design Engineers can move into leadership positions like Technical Lead or Department Manager, or transition into specialized roles like Design Methodology Engineer or Technical Program Manager, with opportunities for further growth in the fields of engineering management, technical sales, or entrepreneurship.
