OS Kernel Engineer for Semiconductor CPU Scheduling Team in Palo Alto, CA
You will join a global Semiconductor CPU experience team modernizing data center for greater agility and productivity, integrating public clouds for faster time to market, empowering digital workspaces to improve mobile experiences, and transforming cyber security.
You will join the Cloud Foundation (CF) virtualization technology team developing the ESXi Operating System. It is an operating system and virtualization infrastructure built from scratch for the explicit purpose of running virtual machines. ESXi is the leading data center operating system in the world, and is used by most large corporations, due to its advanced capabilities, performance, and quality.
The Kernel Memory Resource Management team is responsible for design, implementation, and architectural direction of the memory scheduling kernel subsystem, which is central to the operation of ESXi Operating System. Efficient allocation of memory to virtual machines (VMs) is one of the key differentiators for ESXi, which gives us a strategic advantage over other hypervisors. It is something that we do better than our competition through constant innovation. This allows us to not only increase the scope of the workloads that can be virtualized, but to build strategic relationships, enter new markets and handle security crises.
As a member of VMKernel CPU experience team, you will:Learn the tools and processes necessary to become a successful VMKernel engineer and will participate in the design and development of novel operating system techniques and algorithms for managing both virtual and real computer hardware.
Work closely with a technical lead and your manager to grow in your new position and define goals to continue growing in your career.
Implement advanced kernel-level memory scheduling-related resource management features, with emphasis on scalability, performance, reliability, and support of new hardware technologies.
Work with multiple engineering teams to architect, design, implement and deliver new products based on the enterprise-class VCF virtualization platform.
Take on opportunities to own parts of CPU Scheduling projects and with experience, take on ownership and leading larger parts of projects.
Our work will challenge your systems software development and problem-solving skills!
