Physical Design Signoff CAD Engineer

Job Title

Physical Design Signoff CAD Engineer

Role Summary

Develop and maintain physical-design and signoff CAD flows and methodologies for networking SoCs within NVIDIA's Networking Silicon engineering team. The role focuses on STA, timing closure, power integrity, IR-drop/EM analysis and back-end verification to deliver signoff-quality chips.

Work closely with block owners and full-chip STA engineers to converge designs and resolve complex physical-design issues across multiple projects.

Experience Level

Entry-level / Early-career — 2+ years of relevant full-time experience in physical design, backend CAD, or STA and timing-closure work.

Responsibilities

Primary responsibilities include developing flows, driving signoff readiness, and collaborating across teams.

• Design, implement and maintain physical design, STA, logic equivalence, and power-integrity flows and methodologies for networking chips and SoCs.
• Collaborate with block owners and full-chip STA engineers to achieve timing closure and signoff criteria.
• Perform timing analysis, power and noise analysis, IR-drop and EM checks, and back-end verification.
• Develop and improve tool flows and automation to accelerate convergence and debug complex signoff issues.
• Provide technical solutions and guidance to meet project schedules and quality targets.

Requirements

Must-have skills and experience required to perform the role; nice-to-have items listed separately.

• 2+ years of full-time relevant experience in physical design, backend CAD, STA and timing-closure methodologies.
• Proven experience in Physical Design, Backend CAD, Static Timing Analysis and timing-closure techniques.
• Familiarity with industry-standard tools such as PrimeTime and PrimePower.
• Strong problem-solving skills, attention to detail, and a high degree of ownership.
• Good written, verbal, and presentation skills; ability to work independently and within global teams.

Nice-to-have:

• Experience with signoff tools: PrimeTime, PrimePower, RedHawk, Formality.
• Scripting skills: Tcl, Perl, Python.
• Experience across multiple signoff domains and cross-team collaboration.

Education Requirements

B.Sc. or M.Sc. in Electrical Engineering or Computer Engineering, or equivalent practical experience.
