Job description

Custom Timing and Verification CAD Engineer

Apple's custom silicon is among the most sophisticated in the world — and getting it right requires rigorous transistor-level timing verification and formal verification at every step. Our Custom Timing CAD team builds and owns the flows, tools, and methodologies that make that verification possible. We are looking for an entry-level engineer who is eager to learn, technically curious, and excited to work at the intersection of circuit design and CAD engineering.

Description

In this role, you will support and develop flows for two of the most critical sign-off disciplines in custom IC design — transistor-level timing verification using NanoTime and formal verification using ESP. You will partner closely with analog and digital designers across multiple programs and technology nodes, helping them set up flows, debug issues, and achieve clean sign-off. The work you do will directly shape the quality and schedule of Apple's most advanced chips.

Responsibilities

• Develop, maintain, and improve CAD flows and automation scripts for NanoTime and ESP
• Support design teams in setting up timing and verification runs, interpreting results, and resolving tool and methodology issues
• Drive timing and formal verification closure in collaboration with circuit designers
• Contribute to methodology documentation and guidelines adopted across programs and design organizations
• Engage with EDA vendors to report issues, evaluate new features, and drive tool improvements
• Build automation to improve flow efficiency, reduce runtime, and scale support across concurrent programs

Minimum Qualifications

• BS degree (MS preferred) in Electrical Engineering, Computer Engineering, Computer Science, or related field
• Programming or scripting experience in Perl, Python, TCL, or similar language
• Foundational understanding of digital or custom IC design and static timing analysis through coursework or internship experience

Preferred Qualifications

• Exposure to tools such as NanoTime, ESP, PrimeTime, or HSPICE is a plus
• Knowledge of dynamic logic, memory arrays, or mixed-signal circuit techniques
• Familiarity with SPICE netlists, device models, and parasitic extraction formats such as DSPF or SPF
• Knowledge of formal verification tools and concepts and experience with SystemVerilog RTL
• Interest in AI/ML-driven innovation for CAD workflows
• Strong communicator who can accurately describe technical issues and follow them through to resolution
• Highly motivated and able to work independently in a fast-paced environment
