AppsFlyer & GTM Ownership Manage configurations and serve as the primary subject-matter expert for AppsFlyer and Google Tag Manager (both client-side and server-side) across all brands.

Requirements Experience: 2–4+ years of hands-on experience with marketing tracking/tagging (GTM) and implementation of CAPI or server-side solutions. Technical Skills: Strong proficiency in SQL, with experience querying and validating data within a data warehouse environment (Snowflake preferred). Domain Knowledge: Deep understanding of client-side vs. server-side/API event delivery, mobile measurement platforms (AppsFlyer or equivalent), and the conversion mechanics of Google Ads and Meta Ads. Problem Solving: Proven ability to diagnose production data issues systematically using data analysis rather than trial and error. Communication: Ability to explain complex technical data issues clearly to business stakeholders and collaborate effectively with development teams.
