Screen time has become one of the defining issues of our era, affecting more than 5 billion people who carry a smartphone every day. Public awareness is rising fast, regulators are paying attention and Apple has made Screen Time a headline feature of its recent OS releases. It is also a genuinely interesting moment to be an iOS engineer. The way apps get built has changed more in the last two years than in the previous ten. We want someone who is already living in that change, has built their own way of working with AI, and is improving it while maintaining ownership and a high bar for craft and excellence. Here's why this is the right moment to join: A small team where your work is visible: You'll own real surfaces of an app that millions of people open every day.
