Is This Role For You?

- You want to grow into a leadership role, mentoring junior marketers and shaping team processes within 12 months
- You're fluent in English and comfortable collaborating across distributed global teams
- You prefer strategic planning over tactical execution; this role is hands-on campaign management and optimization
- You lack direct experience managing large product catalogs (200+ SKUs) or e-commerce PPC platforms
- You're not comfortable with ambiguity or rapid iteration; you need everything pre-defined and stable
- You're location-inflexible; this requires 2 days/week on-site in Medellín
