SoC QoS/Fabric Performance Architect, Platform Architecture - Austin, United States
Originally posted 26 October 2026 by the employer.
Model interconnect and memory QoS trade-offs using full-chip C++ simulation for iPhone, iPad, Mac, and Watch SoCs.
About the role
As a member of the Platform Architecture team, you will work with hardware and software engineering groups to define the architecture of Apple's future System-on-Chips (SoCs). You will focus on on-chip communication interconnects and memory Quality-of-Service (QoS) features across iPhone, iPad, Mac, and Watch products.
What you'll do
- Help create a full-chip C++ simulator for iPhone, iPad, Mac, and Watch SoCs. - Model emerging workloads including Augmented Reality (AR) and Machine Learning (ML). - Use performance models to evaluate a range of performance and power trade-offs in SoCs. - Drive architecture improvements for future products based on simulation results. - Collaborate across hardware and software engineering teams to define interconnect and memory QoS features.
What you'll need
- BS degree. - C++ programming experience. - Experience in computer architecture and the HW/SW stack. - Experience with performance modeling and debugging.
Nice to have
- 20+ years of relevant experience. - Examples of substantial HW or SW projects brought to completion. - Coursework and/or practical experience with scripting for automation and data visualization. - Coursework and/or practical experience with network-on-chip architecture and design. - Experience with Cellular/5G modem architecture. - Demonstrated ability to study problems in depth, design experiments, analyze data, and present results.
