Software Engineer Darwin Server, Core OS

The Darwin Server team in Core OS is looking for enthusiastic engineers interested in developing system software for Apples operating systems. Darwin is the UNIX-like foundation at the heart of all Apples operating systems stretching from the kernel up through low-level user components. The Darwin Server team is responsible for ensuring this foundation is adaptable for use in server environments such as with the Private Cloud Compute service that powers Apple Intelligence. nnIn this role youll have an opportunity to dive into complex technical challenges shaping OS architecture and design of cross-functional features actively influencing our technical direction. We are seeking candidates who are eager to learn tackle new problems and drive innovation through their work while actively mentoring and supporting each other in our quest to learn and grow as technical leaders. Our environment values diverse perspectives ideas and collaborative styles with the goal of creating opportunities for everyone to thrive and grow.n

You will be responsible for working on a range of technologies that form the foundation of Apples operating systems with a focus on improving these technologies for use in server and cloud environments. Projects you work on as part of the Darwin Server team could include:nn* Building technologies to enable server application packaging and distribution (like OCI images or Flatpak)n* Enabling Darwin to be integrated with cloud management and orchestration technologies (similar to cloud-init or Kubernetes)n* Improving Darwins support for observability at scale (e.g. OpenTelemetry)n* Developing new security or privacy features to improve Private Cloud ComputennAn engineer on the Darwin Server team would regularly:nn* Participate in all phases of the software development cycle: from problem definition and design through implementation testing and debuggingn* Work with client teams to build the features required for Darwin to meet their development and product requirementsn* Partner with technology owners throughout Apple to enable their technologies for use in server environmentsn* Engage cross-functionally to effect technical change across Applen
