- Lead international growth strategy , identifying priority markets, localizing creative and targeting approaches, and navigating platform and attribution challenges in non-US environments
- Own the MMP stack — maintain integration with mobile measurement partners (Airbridge), ensuring clean attribution, deep link tracking, SKAdNetwork compliance, and fraud monitoring across all paid channels
- Build a full-funnel measurement framework connecting paid acquisition data to in-app product analytics — tracking not just installs and signups, but downstream retention, engagement, and community activation metrics by cohort, channel, and creative
- Partner with the Product and Engineering teams to instrument the right events, interpret retention curves, and feed performance insights back into campaign strategy
- Own creative strategy and testing — develop a rigorous creative testing framework across static, video, and UGC formats; collaborate with design and social to iterate on winning concepts

- Fluency in product analytics tools (Amplitude, Mixpanel, or equivalent) and the ability to independently pull and interpret cohort retention data, funnel analyses, and engagement metrics — not just rely on a BI team to do it for you
