Your work will affect hundreds of millions of users and be essential to the success of some of the most visible current and future Apple features. The role involves understanding the team's priorities; taking ownership of projects or deliverables; designing solutions and building buy-in for those designs; and successful delivery of those designs in order to meet the project goal. The role involves giving technical feedback to colleagues to assist them in the delivery of their designs, features and projects, as well as driving technical standards across the two-site team in collaboration with other senior members of the team. The team has an on-call rota including the week-ends and the successful candidate should expect to handle alerts and other escalations in order to maintain a high level of availability and functionality for our provided services.

You'll learn these tools and have opportunities to improve them. We think critically and strive to balance the best solution with the need to get things done for each engineering challenge we face. Good ideas are heard and results are rewarded. The candidate may be expected to travel to other Apple locations from time to time e.g. the USA.
