Description

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. MINIMUM QUALIFICATIONS Minimum of BS degree in Electrical Engineering, Computer Engineering, Computer Science, or related field + 10 years relevant industry experience Strong programming or scripting experience in Perl, Python, TCL, or similar language Solid understanding of digital or custom IC design and static timing analysis through coursework or internship experience PREFERRED QUALIFICATIONS Hands-on experience with transistor-level timing and formal verification tools such as NanoTime, ESP, PrimeTime, or HSPICE, including flow ownership and methodology development In-depth knowledge of dynamic logic, memory arrays, or mixed-signal circuit techniques, and ability to debug complex timing and verification issues independently Experience with SPICE netlists, device models, and parasitic extraction formats such as DSPF or SPF in the context of timing sign-off Experience with formal verification methodologies and SystemVerilog RTL, including RTL-to-schematic equivalence checking Track record of driving cross-functional collaboration with design, layout, and EDA vendor teams to resolve tool and methodology issues Experience developing or contributing to organization-wide CAD methodology documentation and best practices Familiarity with AI/ML-driven CAD workflows and interest in applying GenAI techniques to flow automation and timing analysis Strong communicator with the ability to present technical work clearly to both peers and management, and drive issues to resolution across teams

Responsibilities

Develop and support CAD flows for transistor-level timing and formal verification to ensure the quality of custom silicon. Partner with analog and digital designers to debug issues and achieve clean sign-off across multiple technology nodes.
