ESX is the operating system and Hypervisor of choice for the majority of the servers in the world, due to its advanced capabilities, performance, and quality. This position is for the ESX CPU and Server platform system kernel team, responsible for the overall Arm and x86 architecture support for ESX kernel and hypervisor. The team owns the core CPU, hardware platform (bring-ups, boot, chipset, drivers, DDK), virtualization (CPU, IO & memory), and engages directly with Arm, Intel, AMD and silicon partners on new technologies. The team collaborates with wider teams and cross BUs to build Arm and x86 support across a wide range of hardware technologies, and engages in research to identify, architect future capabilities and future proof the ESX.  The team maintains a high bar for quality and works with customers as needed to solve issues.

In this role the engineer is expected to be able to successfully work on large systems and hardware enablement projects and collaborate across multiple cross-geo development teams. The candidate should be comfortable with all technical aspects of a project and should be able to represent the team technically internally and externally with partners.  In addition, the candidate would need to collaborate with engineers from partner’s software development teams
