Mobile UA Execution Specialist — 10-week iOS paid-media test (remote)

We're launching an iOS augmented-reality tourism app in Boston this summer and running a structured paid-media test to establish defensible customer-acquisition costs ahead of a fall raise. The test is already designed and the product is ours — we need a hands-on operator to execute it, not a strategist. You will: set up and run six paid-media cells (Meta, Apple Search Ads, Google, TikTok, TripAdvisor) to a pre-defined plan; configure the MMP (AppsFlyer/Adjust/Singular) including SKAN 4 / AdAttributionKit conversion values and fraud protection; instrument and validate end-to-end attribution with our developer (web app + iOS app); run a pre-launch smoke test; manage pacing, caps, and reallocation; and report weekly on clean per-cell metrics. Must-have: hands-on iOS UA across Meta and Apple Search Ads; MMP setup and iOS-privacy attribution fluency; and a real grasp of incrementality / geo-based measurement — you know why a platform's reported CAC overstates paid. Nice to have: subscription/eCommerce-web-funnel experience, the travel vertical, ASO. ~10 weeks, part-time, fixed scope, start ~July 1.
