About the Team

Nutanix Cloud Infrastructure is designed to enable the broadest range of virtualized server workloads to run on widely available server hardware, utilizing direct attached flash drives to provide scale-out storage, and integrated with compute and networking services. Customers can choose from multiple hypervisors options, including our own increasingly popular open-source based Acropolis Hypervisor (AHV), to utilize the latest CPU and platform technologies. The rapid development of advanced CPU and memory technologies - as well as the rising prominence of compute-intensive workloads in the datacenter - provide Nutanix with unprecedented engineering challenges and opportunities for product innovation. What's unique about our Core Platform Software CPU enablement team at Nutanix is that we are on the cutting edge of the latest CPU and platform technologies from the industry leading vendors. We engage in new technology and open-source analysis far in advance of new CPU launches, and we get hands-on access to very early equipment to engineer software support for the latest compute technologies. We also interact closely with other Nutanix engineering teams and collaborate on software layers across our stack.

Your Role

• Collaborate with cross functional teams (Acropolis OS, AHV, Foundation, etc.) to enable new CPU and new compute technologies for the Nutanix core product stack.
• Technical analysis of new processor and CPU platform technologies including CPU, memory and PCIe as well as integrated CPU accelerators.
• Develop and maintain software that monitors and governs hardware platform functionality, including power state management, memory RAS, PCIe error handling, and support for predictive failure indicators.
• Evaluate and integrate upstream Linux kernel patches and system utilities to support new CPU generations.
• Perform early hypervisor software bring-up on CPU simulators, prototype platforms, and pre-production systems from server vendor partners.
• Build tooling for CPU performance counters, memory bandwidth utilization, NUMA performance, and PCIe bus utilization.
• Ensure broad compatibility of Nutanix AHV hypervisor with industry standard server platforms.
• Drive reliability and performance improvements in the Nutanix software stack through Linux kernel advancements, OS/hypervisor tuning, and BIOS optimizations.
