We are looking for a Junior–Middle User Acquisition Manager to help us scale our portfolio of consumer mobile apps through Meta Ads.

What you’ll be responsible for

• Launching, managing, and optimizing Meta Ads campaigns for iOS mobile apps.
• Building and managing a structured testing pipeline for:
  • creative concepts;
  • hooks and marketing angles;
  • audiences;
  • offers;
  • geos;
  • campaign structures;

What we offer

You will work directly with the founder and have a lot of ownership over the acquisition process.

We are actively building and launching consumer mobile apps, so there will be plenty of room to test ideas, learn quickly, and directly influence growth.
 

This role is a good fit for someone who wants to grow from a strong Junior / Middle UA specialist into a person who can eventually own paid acquisition and scaling for multiple mobile products.
