Head of User Acquisition / User Acquisition Coach - Advisor

About the role

Our gaming business builds and scales a portfolio of casual, ad-monetized evergreen games (cards, words, puzzles, board games) from Barcelona. We’re rebuilding it as an AI-native team: instead of departments and management layers, we work in small squads, and each squad runs like a small studio that owns 1–3 games end to end: product, UA and monetization together. The reporting, coordination and analysis that used to need middle managers are handled by shared data and LTV models, AI agents and automation.

The model follows "From Hierarchy to Intelligence" by Jack Dorsey (Block) and Roelof Botha (Sequoia Capital), and uses a few simple roles:

• Builder (IC): everyone builds.
• DRI (Directly Responsible Individual): owns one result end to end, has real authority over the squad’s effort and picks the team. It’s a role, not a rank.
• Player-coach: sets the standard of a discipline for all squads and makes their expertise easy to reach. A coach is accountable for the standard and for being available, not for other people’s numbers or growth.
• Advisor: brings outside expertise without owning a result.

There’s no UA department in this model: UA specialists sit inside the squads and work with their squad’s DRI. What we need is senior UA judgment available to every squad and one clear UA standard across the portfolio. Eleven of our games run active UA, and UA is the biggest lever on our profit and growth today.

We’ll fill this seat in one of two ways:

• In-house (Head of UA): builder and UA Coach. Full-time in Barcelona, 4 days a week in the office. You run UA hands-on for 1–3 games inside one squad and set the UA standard for all squads.
• Advisor (UA Coach): not employment. You set and keep the UA standard and make UA expertise easy to reach for every squad. Scope and hours are agreed together.

Responsibilities:

As UA Coach (both formats):

• Set and keep the UA playbook every squad works to: channel mix, bidding and budget rules, ROAS discipline and when to kill a campaign.
• Own the creative testing framework, measurement and incrementality, and how we test new networks and DSPs.
• Make UA expertise easy to reach: regular office hours with squad DRIs and UA specialists, campaign and creative reviews, written playbooks and worked examples, and introductions in the market where they help.
• Speak up when a standard isn’t followed.

In-house, hands-on in one squad:

• Run and optimize UA for 1–3 games yourself, as the reference for how UA is done here.
• Turn data from our shared LTV and profit models into growth decisions, without a dedicated analyst.
• Build agents and automation that take over UA work: bidding, reporting and creative production.

What this role is not:

• Not a head of a UA department: there’s no team to manage. UA specialists report to their squad’s DRI.
• Not accountable for squad or portfolio numbers: each squad’s DRI owns their result. You’re accountable for the UA standard and for being available.

Requirements:

• 7+ years in mobile user acquisition or growth marketing, including leadership roles, in ad-monetized casual evergreen games.
• Hands-on experience running and optimizing campaigns across AppLovin, Meta, Google, DSPs and CPI networks.
• You’ve scaled mobile games through performance marketing and kept them profitable.
• Strong creative-driven UA: you’ve built a creative testing framework and know how to read its results.
• Strong analytical mindset: you turn data from shared analytics and LTV models into growth decisions and are comfortable without in-house analysts.
• AI-native: agents or automation you built that took over UA work (bidding, reporting, creative production), not only tools built by others.
• You work both at the strategic level and in day-to-day execution, and can explain a standard so that people outside UA can apply it.
• For the in-house format: ready to relocate to Barcelona and work from our office 4 days a week.

Nice to Haves:

• Experience scaling games to the top-grossing charts.

Why Join Us?

• UA is the biggest lever on our growth, and you’ll set how we use it across the whole portfolio.
• You choose the format that suits you: full-time in Barcelona or as an advisor.
• You’ll help shape how an AI-native games team works, with small squads that move fast and act on what you bring.
