Performance Creative Specialist (UA - App/Game)

Crossian is a technology-driven e-commerce business. Behind our success is our people. As a start-up formed in 2020, we have created a fast-paced and dynamic environment, enabling our people to reach a cumulative average growth rate of over 1000% in just under 3 years.

To support our mission of building Direct-to-Consumer brands and increasing customer lifetime value, we are scaling our team from 350 to 600 talents in 2026. Join us as we redefine the future of global commerce.

At Crossin, we leverage AI to automate data analysis and campaign optimization — so creative has become the real competitive edge in user acquisition. We're looking for a Performance Creative Specialist who turns market and data insights into winning ad creatives: someone with strong content development instincts and enough performance-marketing sense to know what the data is telling them, ready to steer the AI algorithm toward the creatives that scale.
