We're modernizing data centers for greater agility and productivity, integrating public clouds for faster time to market, empowering digital workspaces to improve mobile experiences, and transforming cyber security.


ESXi Operating System is at the core of VMware Cloud Foundation's (VCF) virtualization technology. It is a platform built from scratch for the explicit purpose of running virtual machines and containers. ESXi is widely used by most large corporations, due to its advanced capabilities, performance, and quality.


The VMKernel Core team is responsible for the design, implementation, and architectural direction of the VMKernel – the operating system kernel for ESXi. The VMKernel Core team works across ESXi but its focus is the core kernel subsystems providing key functionality used by other groups within VMware by Broadcom as well as partner companies.

  • 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.
  • Design and implement kernel locking techniques, filesystems, various forms of kernel APIs to interface with device drivers (vmkapi) user programs (POSIX) and other subsystems and invent new OS security and patching infrastructures.
  • 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 the core kernel infrastructures and with experience, take on ownership and lead larger parts of projects.

Requirements:
  • BS degree in Computer Science or related field and 8+ years of relevant industry experience. Or MS degree in Computer Science or related field and 6+ years of relevant industry experience. Or PhD and 3+ years of relevant industry experience

  • Extensive kernel-level development experience and expertise with synchronization in preemptive multi-threaded environments. Experience with Intel x86 CPU architecture and Intel based server architecture. Similar experience and understanding of AMD architecture, a plus.
  • Excellent analytical, debugging and C programming skills
  • Strong verbal and written communication skills
    Must have legal authorization to work in the US
