Virtualisation Engineer

The Virtualization team is looking for a highly skilled and motivated software engineer to join our core development group. We are responsible for building the foundational virtualization technologies that power innovative features, enabling developers and users to run diverse operating systems and environments reliably on their Mac. As a member of this team, you will work at the heart of our virtualization stack, contributing to the kernel-level support, the Hypervisor framework, and the Virtualization framework. This is a unique opportunity to work on low-level system software, influence hardware-software co-design, and build highly reliable systems that are critical to the Apple ecosystem. If you are passionate about operating systems, computer architecture, and building robust, high-performance systems, we encourage you to apply. Key Responsibilities - Design, implement, and maintain kernel-level virtualization support for Apple platforms. - Develop and enhance features within Apple's Hypervisor and Virtualization frameworks. - Implement and improve device emulation and bus emulation logic to support a wide range of virtualized hardware. - Collaborate with hardware teams to integrate support for new virtualization-related features. - Write high-quality, well-tested, and maintainable code in C/C++. - Design and implement comprehensive test suites to ensure the reliability and correctness of virtualization components. - Debug complex issues spanning kernel, hypervisor, user-space, and guest operating system layers. - Optimize performance of virtual machines. - Work cross-functionally with other teams (e.g., drivers, frameworks, QA) to deliver integrated solutions. - Participate in code reviews and technical design discussions.
