Job description

Summary

Do you love creating sophisticated solutions to highly complex challenges? As part of our Silicon Technologies group, you’ll help design and manufacture our next-generation, high‑performance, power‑efficient GPU! You’ll ensure Apple products and services can seamlessly and expertly handle the tasks that make them beloved by millions. Joining this group means crafting and building the technology that fuels Apple’s devices. Together, we enable our customers to do all the things they love with their devices.

Description

This role requires a mix of strategic engineering along with hands‑on, technical work, being responsible for implementing complete chip design from netlist to tape‑out, and having hands‑on experience in physical design and large chip integration.

Responsibilities

• Collaborate with FE team to understand chip architecture and drive physical aspects early in the design cycle.

• If you are a confident problem solver who thrives under pressure to find new, creative solutions, we are excited to hear from you!

Minimum Qualifications

• MSEE or equivalent is required.
• Deep experience with all aspects of ASIC integration including floorplanning, clock & power distribution, global signal planning, I/O planning and hard IP integration.

Preferred Qualifications

• Knowledge of issues such as multiple voltage and clock domains, ESD strategies, mixed signal block integration, and package interactions.
• Familiar with hierarchical design approach, top‑down design, budgeting, timing and physical convergence.
• Depth of expertise on integrating IP from both internal and external vendors and be able to specify and drive IP requirements in the physical domain.
• Experience with large subsystem designs (over 20M gates) with frequencies in excess of 1 GHz applying brand‑new technologies.
• Familiar with various process related design issues including design for yield and manufacturability, multi‑Vt strategies and thermal MGT.
• From a CAD tool perspective, experience with floorplanning tools, P&R flows, global timing verification and physical design verification flows is required.
