App Attribution & Growth Specialist
We're looking for an App Attribution & Growth Specialist — someone who has spent years in mobile UA and, at some point, got pulled into the messy side of things: tracking that didn't match, attribution that didn't make sense, data pipelines that broke at the worst possible time. Instead of ignoring it, you leaned in. You've debugged installs at 2am, questioned MMP logic, checked raw tables in BigQuery, and thought there has to be a better way to do this. Now you’re looking for something different. Not just running campaigns. Not just fixing things alone. You’re looking for a place where you can work on a portfolio of apps, go deeper into how growth actually works under the hood, and be surrounded by people who are as curious and stubborn as you are.

* Debug issues across the full funnel: click → install → event → revenue
o Click → Install → Event → Revenue

o Ad Networks (Meta, TikTok, Google, ASA, programmatic, etc.)
o Data Warehouse (BigQuery / Databricks)
o Product & analytics layer (e.g. Firebase)
* Design and validate postbacks (S2S), event mappings, attribution logic & windows
* Work on Web2App flows: capture parameters on landing pages, stitch into app attribution
* Configure and maintain deep linking / OneLink setups: parameter passing, click_id logic, deferred deep linking
* Collaborate with UA, Product, and Engineering: validate SDK implementations, ensure events are triggered correctly, raise and propose fixes when something breaks
* Work with subscription & monetization data: integrate RevenueCat / Adapty, handle webhook / S2S flows into the warehouse
* Support UA Managers by ensuring data reliability and correct implementation of campaign signals (events, revenue)
