Company Overview:
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. Broadcom is a global technology leader designing, developing and supplying a broad range of semiconductor and infrastructure software solutions.

Role Description:
This position is for the ESXi CPU & Server Platform system kernel team, responsible for the overall Arm & x86 architecture support for ESXi kernel and hypervisor. 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. ESXi 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.

Responsibilities:
The team owns the core CPU, hardware platform (bring-ups, boot, chipset, drivers, DDK), virtualization (CPU, IO & memory), and engages directly with Arm, Intel and silicon partners on new technologies. You will collaborate with wider teams and cross BUs to build Arm & x86 support across a wide range of hardware technologies, and engage in research to identify, architect future capabilities and future proof the ESXi. The team maintains a high bar for quality and works with customers as needed to solve issues.
In this role, you are expected to successfully work on large systems and hardware enablement projects and collaborate across multiple cross-geo development teams. You should be comfortable with all technical aspects of a project and should be able to represent the team technically internally and externally with partners. You will collaborate with engineers from partner’s software development teams to jointly develop solutions on ESXi. You would be part of a strong technical team working across the full stack from bootloader to configuration scripts, fostering a research mindset focused towards developing new solutions.

Requirements:
* 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 OR PHD in Computer Science, Computer Engineering or equivalent and 3+ years of 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.).
* 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.
* Must have legal authorization to work in the US.

Desirable Skills:
* Familiarity with virtualization platforms, such as ESXi, 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.
