About The Role
This is a senior, hands-on media buying role with end-to-end ownership. You will own the whole acquisition process on Paid Social acquisition channels: strategy, account structure, bidding, budget allocation, creative testing, measurement, scaling and account health. You decide what to test, what to scale and what to cut, and you are accountable for the results. We need someone who has already run Paid Social Ads at scale, who knows how to grow profitably in a policy-sensitive niche, and who can operate independently on large budgets. You will manage performance against real revenue data (CPA, FTD, ROAS, payback, player LTV and cohorts), not surface-level platform metrics. Own the process end-to-end: take full ownership of acquisition across all paid social ad networks (TikTok, Meta, AppLovin, Snapchat, and more): planning, launch, optimization, scaling, reporting and documentation. Scale spend profitably in the US market while holding payback, ROAS and CPA targets based on real revenue and player-value data. Build and optimize account structure, conversion events, value-based bidding and budget allocation across paid social networks. Decide budget allocation across acquisition channels and find new scaling levers: audiences, formats, placements, campaign types and additional channels. Run a structured, high-velocity creative testing process with the creative team on all channels, with clear hypotheses and kill/scale rules. Manage signal quality: conversion events, event value,



deposit / purchase optimization, attribution. Document tests, learnings and playbooks, and use Claude and automation to speed up builds, QA, reporting and optimization. 5+ years of hands-on paid social / user acquisition experience. Large-scale experience running acquisitions in the US market. Hands-on AppLovin (AppLovin Ads / AXON) experience, scaling it as an acquisition channel. Direct ownership of large budgets, ideally $1M+/month hands-on. LTV, ROAS, payback windows, cohorts, high-value-user dynamics and value-based optimization. Strong creative testing discipline and measurement rigor. Ownership mentality: you run channels end-to-end with minimal supervision and take responsibility for outcomes.
