At Meta, we continuously optimize our workloads with the goal of reducing their resource requirements. Newer server generations arrive at our datacenters with enhanced hardware capabilities, incentivizing us to rethink, redesign, and reimplement key algorithms. We explore SIMD vectorization, offloading, and leveraging new instruction sets. This iterative process is carried out by constantly updating CPU instructions, low-level kernel instructions, and testing and profiling workloads on new systems. Our solutions may lead to general software optimizations that also impact older servers. As a member of our team, you'll have the opportunity to work with top talent in the industry, collaborating with highly skilled engineers and researchers who are experts in performance optimization and software development. You'll be contributing to Meta's infrastructure evolution, playing a critical role in shaping the future of our technology stack. If you're excited about working on cutting-edge technology, driving innovation, and making a meaningful impact on our infrastructure, we'd love to connect with you.
