Is This Role For You?
- You've shipped performance campaigns on Google UAC, Meta, or TikTok at scale and can speak fluently about CPI/CPA/LTV tradeoffs
- You're comfortable with MMP setup, event tracking, SKAN nuances, and deep linking-and enjoy debugging attribution
- You thrive in hands-on roles where you execute *and* lead; you want to mentor others without waiting for a manager title
- You work in Portuguese or can ramp quickly; you're excited about e-commerce and repeat-purchase growth loops
- You have direct experience working with Product and BI teams to move the needle on retention and lifetime value
- You're purely a strategist-this role requires you to run campaigns, analyze data, and optimize in real time
- You need full remote flexibility; this is on-site in São Paulo
- You lack direct hands-on MMP or mobile marketing experience; the role expects technical depth from day one
- You're not comfortable with Portuguese-language stakeholder communication or don't have appetite for navigating a large, traditional retail organization
