Software Engineer ESX CPU & Server Platform

At VMware by Broadcom, we are building new possibilities for our customers by accelerating digital business transformation. 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.

ESX 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. 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

to jointly develop solutions on ESX. The candidate would be part of a strong technical team that is fully motivated and engaged, working across the full stack from bootloader to configuration scripts.  Further, the candidate is expected to foster a research mindset focused towards developing new solutions.

Requirements:

• Minimum BS degree in Computer Science, Computer Engineering or equivalent and 8+ years of relevant industry experience Or MS degree in Computer Science, Computer Engineering or equivalent and 6+ years of relevant industry experience.
• Excellent C programming skills.
• Solid understanding of modern microprocessor architectures (multiprocessor

programming, cache architecture, barriers etc.).

• Strong operating systems and kernel internals knowledge such as Linux/BSDs/Windows NT.
• Good knowledge of modern computer systems, esp. around I/O - x86 PC or

ServerReady Arm. (PCI, ACPI, IOMMUs, DMA, UEFI, etc.).

• Hands on experience in developing OS/Kernel features, device drivers and system software components.

• Expertise in version control and collaborative code review tools such as git, gerrit, perforce.
• Ability to understand, create, modify, and troubleshoot build issues, makefiles, linux shell scripts.
• Self-starting – you will be frequently working outside your or your teammate’s comfort zones.
• Strong analytical and debugging skills.
• Excellent oral and written communication skills.

Desirable:

• Familiarity with virtualization platforms, such as ESX, KVM, Hyper-V.
• Experience with hardware bring-ups: CPU, boot loaders, chipset, SMP/NUMA, interrupt controller, SMMUs, PCIe quirks.
• Familiarity with hardware virtualization technologies.
• Assembly (Arm or x86 or RISC) programming experience.
• Arm Architecture knowledge highly desirable (AArch64/ARMv8 preferred).
• Familiarity with kernel performance analysis and optimization.
