Senior Compute Runtime Software Engineer

The Apple Services Engineering (ASE) team builds the container and virtualization runtime technology that powers Apples next-generation compute platform. Were 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 filling multiple roles on this team both junior and senior. Were 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 whether thats engineers early in their systems programming career looking to grow fast on a high-paced experienced team or seasoned domain experts ready to take ownership of significant technologies.n

We build the container runtime technology that Apples 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 not a web-services or operations 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 Apples own hardware in the data center at a scale and with constraints the rest of the industry hasnt 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 looking for a domain expert with depth across multiple technical areas someone used to designing major features and resolving highly complex ambiguous problems creatively taking ownership of significant technologies to drive real impact across the organization ready to take risks course-correct quickly and drive ideas from inception to implementation building a reputation as someone the broader org seeks out for technical direction and standards and to actively mentor engineers at all love open source and collaboration at every level.n
