## About the role

As the founding technical lead, this expert will spearhead the HW/SW co-design of next-generation HBF–xPU systems, translating complex AI workload traces into precise architectural policies for caching, prefetching, and data movement. The role demands deep hands-on expertise in memory controllers and performance modeling to define interface contracts and optimize system-level efficiency across the hardware and software stack.

## What they're looking for

- Experience owning system architecture decisions, technical requirements, interface definitions, and performance acceptance criteria across multiple hardware and software components
- Experience defining functional partitioning and interface contracts across hardware, firmware, drivers, compiler/runtime, and application software
- Experience developing or extending simulation tools for architectural modeling using Python, C/C++, SystemC, or comparable modeling environments, including event-driven, trace-driven, or queueing-based models
