Compute Runtime Software Engineer

The Apple Services Engineering (ASE) team builds the container and virtualization runtime technology that powers Apple's next-generation compute platform. We're a fast-moving, highly skilled team of systems engineers designing and developing the virtualization-based runtimes that run Virtual Machines and Linux Containers across our data center and Apple platforms — with privacy, security, and performance as first-class requirements. Beyond the datacenter, we maintain Apple Container, our open source project bringing native container support to macOS desktops.

We're looking to add talented, passionate people who love hard systems problems and want to build foundational technology used across Apple and the open source community — engineers early in their systems programming career looking to grow fast on a high-paced, experienced team.

We build the container runtime technology that Apple's own services and developers depend on. Our systems engineers develop virtualization-based runtimes — using macOS virtualization and VMM solutions like Cloud Hypervisor and sandboxed container solutions — to run Virtual Machines and Linux Containers across our data center and Apple platforms, with a relentless focus on privacy, security, and performance. This is a foundational systems team: we work at the level of kernel and container security, image distribution, filesystems, and virtualization. Much of this work is greenfield, solving problems unique to running on Apple's own hardware in the data center, at a scale and with constraints the rest of the industry hasn't had to solve for. Beyond the datacenter, we maintain Apple Container, our open source desktop tooling that lets developers around the world run containers natively on macOS.

We're looking for a strong foundation in systems programming and a genuine curiosity about how containers and virtualization work under the hood, paired with the drive to learn quickly on a high-paced, experienced team.

We love open source and collaboration at every level.
