Compute Runtime Software Engineer

Compute Runtime Software EngineerThe 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 filling multiple roles on this team, both junior and senior. 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 — whether that's 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.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.Minimum QualificationsBachelor's Degree in Computer Science, or equivalent related experience.At least 3+ years of Software design and development experience in infrastructure engineering (compute, storage and network virtualization), containerization, or systems programming, with strong fundamentalsProgramming proficiency in C, C++, Swift or GoFamiliarity with some or all of the following topics: Linux containerization, Linux filesystems, Image distribution, Content storage, Kernel and container securityAbility to contribute to design docs and technical discussions, and to write clear, well-tested codeLove open source and collaborationPreferred QualificationsExperience with Linux system programmingExperience participating in code review, giving and receiving feedback on correctness and test coverageExposure to writing tests for regression prevention or negative-case validationDevelopment experience in one or more of: Cloud security, Container / Linux Kernel security and API securityExperience troubleshooting and diving into metrics to identify resource contention and bottlenecksExperience designing benchmarks and load tests to characterize performance and establish scalability modelsDevelopment experience with container orchestration systems such as Docker, Kubernetes or Mesos is a plusDevelopment experience with virtualization and container technologies such as Apple Container, Kata, Firecracker, or KubeVirt is a plusSystems programming experience on Darwin with Swift is a plusProgramming system virtualization based on Cloud Hypervisor, rust-vmm, macOS Virtualization Framework, QEMU, or KVM is a plusPay & BenefitsAt Apple, base pay is one part of our total compensation package and is determined within a range. This provides the opportunity to progress as you grow and develop within a role. The base pay range for this role is between $142,300 and $263,300, and your base pay will depend on your skills, qualifications, experience, and location. Apple employees also have the opportunity to become an Apple shareholder through participation in Apple's discretionary employee stock programs. Apple employees are eligible for discretionary restricted stock unit awards, and can purchase Apple stock at a discount if voluntarily participating in Apple's Employee Stock Purchase Plan.

You'll also receive benefits including: Comprehensive medical and dental coverage, retirement benefits, a range of discounted products and free services, and for formal education related to advancing your career at Apple, reimbursement for certain educational expenses — including tuition. Additionally, this role might be eligible for discretionary bonuses or commission payments as well as relocation.
