About the role

Senior UA role joining a pre-PMF AI companion startup to build and own paid acquisition from zero, collaborating directly with founders to shape growth and scaling across US, Japan, and Korea.

Responsibilities

  • Paid UA from zero. Channel selection, media plan, test structure, budget logic. You decide what we try first and why.
  • Finding what works. Geo × channel × creative × audience.
  • The numbers. MMP setup, attribution, cohorts, CAC / ROAS / LTV. Including the part where you tell us the math doesn't converge.
  • Creative direction. You'd brief it yourself at first, and later help us hire a dedicated creative producer and set up the production pipeline together.
  • Store and platform moderation. AI companions sit in a sensitive category almost everywhere. Navigating that is part of the job here.

Qualifications

  • 4+ years in paid UA on mobile consumer products. Gaming or entertainment is a strong plus.
  • Buying experience in Japan, or across Asia more broadly (Japan / Korea). This is the one that matters most to us.
  • Experience running meaningful budgets. We're not looking for a specific number, but we want someone who has been through a scale, not only through tests.
  • Mobile ad networks (AppLovin, Unity, Moloco, Mintegral, Liftoff) — hands-on.
  • Meta and TikTok — creative-driven buying, where you've owned the pipeline and not only the account.
  • Google App Campaigns as a working baseline.
  • Apple Search Ads and Japanese platforms (LINE Ads, Yahoo! Japan) — a strong signal, though we don't expect all of it.
  • You read cohorts before you read spend, and you're comfortable killing your own campaigns.
  • A feel for global consumer culture and where trends move. We build for the US, Japan, and Korea.
  • Working English. Plus Russian, Ukrainian, or Belarusian — that's how the team talks internally today.

Benefits

  • Remote across Europe, Warsaw hub — coworking covered wherever you are.
  • 29 days of paid leave.
  • Care bonus to spend on benefits that matter to you.
  • Any hardware you want.
  • A small team that has done this before, and a product with no precedent to copy.
  • Your first campaign live within weeks of joining, not quarters.
