Job description
As an ASIC STA Engineer at Apple, you will play a crucial role in the timing aspects of SoC design. Your work will involve timing sign-off, developing STA and sign-off flows, and managing timing constraints for both regular and custom requirements. You will collaborate closely with RTL designers, CAD teams, and physical design teams to ensure timing closure and high-quality sign-off. This position requires innovation in timing constraints and flow to address potential issues in timing analysis.
Requirements
- Bachelor of Science in Electrical Engineering.
- Proven knowledge of the ASIC design timing closure flow and methodology.
- 2+ years of experience in writing ASIC timing constraints and timing closure.
- Expertise in STA tools such as Primetime and knowledge of timing corners/modes.
- Hands-on experience in timing/SDC constraints generation and management.
- Proficient in scripting languages such as Tcl and Perl.
- Familiarity with synthesis, DFT, and backend related methodology and tools.
- Strong communication skills.
Responsibilities
- Perform timing sign-off and develop STA and sign-off flows.
- Own IP and block level timing constraints from synthesis to sign-off.
- Collaborate with RTL designers to understand design intent and clock structure.
- Work with CAD teams to develop and understand flow.
- Engage with the physical design team to close and sign-off timing.
- Innovate timing constraints and flow to facilitate timing closure.
- Verify timing constraints and address potential pessimism in timing analysis.
Benefits
- Employees at Apple are often offered comprehensive benefits that support physical and mental well-being—flexible medical plans, confidential counseling, onsite wellness centers at major campuses, and resources for fitness and daily life. Families typically receive fertility support, paid parental leave with gradual return, caregiving leave, and dependent-care guidance, while financial perks commonly include stock grants (with purchase discounts), 401(k) matching, and income-protection coverage. Employees also see robust time off, Apple University learning and tuition reimbursement, donation matching and paid volunteer hours, and deep product and partner discounts.
