## Description

We are seeking a Workload Porting & Performance Engineer to evaluate new hardware platforms by porting benchmarks and real-world workloads, analyzing performance, and identifying system bottlenecks.

In this role, you will bring up workloads on new systems, characterize performance behavior, and adapt workloads to better utilize hardware capabilities. You will play a critical role in validating new platforms and ensuring that performance aligns with expectations across compute, memory, and networking subsystems.

This role requires strong hands-on experience with performance analysis, workload optimization, and system-level debugging across hardware and software boundaries., * Port and enable benchmarks and real-world workloads on new hardware platforms.

 * Evaluate system performance across compute, memory, storage, and networking subsystems.
 * Identify and analyze performance bottlenecks and inefficiencies.
 * Adapt and optimize workloads to better utilize hardware capabilities.
 * Develop and run performance experiments and profiling workflows.
 * Compare expected vs. observed performance and provide feedback to:
 + hardware architecture teams
 + performance modeling teams
 + system and software engineers.
 * Debug issues across the stack, including software, runtime, and hardware interactions.
 * Provide actionable insights to guide platform readiness and deployment decisions.
