Hybrid | Senior Level | Full Ownership

We are not looking for a campaign operator. We are looking for someone who knows how to scale app growth — and wants to build something meaningful. Appiness is an AI-powered App Growth Partner turning app users into shoppers. We don’t optimize for cheap installs. We optimize for incremental post-install value. Now we are hiring the person who will help build and scale our Media Buying capability together with our Head of Supply. This role starts deeply hands on. Shortly, you will evolve into Media Buying Lead and build the team around you.

Your job is to make them work.

You will:

• Launch and optimize campaigns across new traffic sources
• Structure testing frameworks

• Adjust (preferred)
• AppsFlyer / Singular or similar

You understand:

• Postbacks & event mapping
• SKAN complexity
