Core OS Build Engineer


Tokyo, Japan

full time

06 Oct 2020


As Build Engineer, you’ll oversee the build and verification process of the Kernel and related components for all of Apple’s OS releases. You’ll work as part of an agile team that is big on shortening feedback cycles for our internal customers.

Our aim is to provide fast feedback to all of our stakeholders. You will work hands-on with various tools to raise the bar for automation of day-to-day operations and rapidly deliver innovative solutions.

Key Qualifications

  • Demonstrate proficiency with scripting languages (Python, Perl, Bash)
  • Experience with creating, running, and troubleshooting native builds (Objective-C, C++) if you are the right person, we don’t mind which technology you are used to, as long as you show flexibility
  • Comfortable writing code and ideally have experience with TDD
  • Always iterating and seeking new ways to shorten the feedback cycle of build pipelines
  • Will work closely with engineering and QA teams, which requires very good communication and coordination skills
  • Proficient using Git and other version control systems
  • Experience with Docker and Kubernetes as well as modern configuration management tools like Salt/Ansible would be a big plus

We are working to take the build and test process of the low-level components of iOS, macOS, watchOS and tvOS to the next level (think kernel and low-level libraries). We don’t have all of the answers on how to do that yet, perhaps you do? We are exploring, measuring and trying new things. We are responsible for validating nearly a quarter of all changes that go into our OS releases and affect 1 billion+ customers, so this isn’t just a theoretical exercise. We won’t be satisfied with anything less than outstanding.

Education & Experience

  • B.S. in Computer Science or equivalent experience
