- • Ability to run structured A/B tests, analyze full-funnel performance, and translate data into rapid, informed decisions.
- • Proactive, self-driven mindset with strong ownership of performance outcomes and comfort managing multiple campaigns and priorities simultaneously.
- • Excellent communication and collaboration skills, with experience working closely with creative, product, and analytics teams to align on KPIs and deliver data-backed insights.
