Senior iOS Engineer, Ads & Monetization Platform

Our team owns NewsBreak’s first-party monetization stack end to end — from the client, through the auction server, to our in-house ad platform. 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.

Responsibilities

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; Measure your own work — ship behind experiments and be able to show that an experience change didn’t cost revenue

Requirements

3+ years of production iOS development in Swift and/or Objective-C; 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 third-party content inside a native app; Strong debugging instincts — can work backward from a crash stack and sparse logs to a root cause without a reliable local repro, and comfortable investigating systems without source; Judgment about AI tools — uses AI coding assistants as part of normal workflow and can articulate where they help and where to override; Comfort with numbers — shipped behind experiments and can reason about metric movement; Ownership — spots problems, defines them, drives them to done, and treats shipped as start of responsibility; Clear communicator comfortable working directly with product, QA, and other non-engineers

Nice to have

Mediation or in-app bidding experience; SDK development experience — public API design, backward compatibility, dependency discipline; Background in feed, video, or other latency-sensitive surfaces; Familiarity with mobile privacy and consent frameworks
