It’s a small team with wide surface area, which means two things: the distance between the code you write and the revenue it drives is very short, and you’ll own your area outright rather than picking up tickets from a queue. You’ll be the person responsible for how ads load, render, and behave on iOS — in our own app, in the SDK we ship to third-party publishers, and across the external ad networks we mediate. What You'll Do Build and maintain iOS ad functionality across our app and our publisher-facing SDK Own ad rendering and the ad experience: how creatives load, display, and perform, for both rich-media and native formats Own viewability and event accuracy — impressions, clicks, and billing signals have to be right, and they have to reconcile with what our partners measure Own the client-side mediation layer: how we request, prioritize, cache, and fall back across demand sources Integrate and maintain external ad SDKs (Google, Meta, and others) through version upgrades and platform changes, and own the tradeoffs when their behavior conflicts with ours Own production health for the iOS ad stack — you’re the person who responds when something breaks, including problems originating inside vendor SDKs you can’t see into. Ad code ships in our app and in our publishers’ apps, so a rendering bug is an app stability problem, not just a bad ad Measure your own work — ship behind experiments and be able to show that an experience change didn’t cost revenue What We're Looking For 3+ years of production iOS development in Swift and/or Objective-C. We care more about the depth of what you’ve owned than the exact number of years. You’ve owned a meaningful module end to end — design, implementation, launch, and the aftermath. Experience with ad rendering standards such as MRAID or OMID — or comparable experience rendering...
