Job Description

Embedded Kernel ESX Engineer

Overview: As a member of the ESX Core Platform Quality team, you will contribute to the design and development of novel validation techniques and algorithms for ESX OS that manages virtual and real computer hardware. The role focuses on delivering high-quality software solutions for the ESX hypervisor, ensuring the reliability, scalability, and performance of the platform used by major enterprise customers.

You’ll work closely with a technical lead and manager, gaining valuable experience and developing core competencies in kernel-level memory scheduling, OS virtualization, and hardware resource management. As you progress, you’ll take on greater ownership and leadership responsibilities in validation projects for ESX core platform components.

Responsibilities:

• Collaborate with engineering teams to design, implement, and validate new test coverage for ESX kernel and user space features.
• Focus on scalability, performance, reliability, and support for emerging hardware technologies in data centers.
• Develop and implement advanced test strategies to ensure ESX is a reliable, enterprise-class platform.
• Take ownership of parts of validation projects, progressing to larger project leadership roles as experience grows.
• Focus on low-level system software, primarily dealing with kernel and memory management, device drivers, and resource management.
• Troubleshoot and debug complex systems to optimize ESX OS performance and enhance reliability.

Requirements:

• 8+ years of relevant industry experience
• Strong experience with kernel-level OS architecture, particularly Linux, Unix, Solaris, BSD-like systems, or embedded real-time Operating Systems.
• Advanced proficiency in C and Python for systems development, debugging, and automation.
• Deep expertise in OS virtualization, particularly hypervisors such as ESXi, Hyper-V, KVM, or XEN.
• Solid understanding of memory scheduling, memory management, CPU management, and hardware resource management.
• Experience working with Intel x86 CPU architecture and server architectures (AMD experience is a plus).
• Desired Technical Skills:
• Experience with OS resource management and virtualization.
• Understanding of underlying hardware architecture (BIOS, device drivers).
• Ability to work on low-level system components with a focus on reliability and performance.
