Senior Digital Marketing Specialist (AI Focus)

Công việc cụ thể là gì?

ABOUT THE ROLE 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. At Crossian, our AI agent system automates the operational side of performance marketing. That changes what we need most from people. This is a senior individual-contributor role, not a people-management one: you lead through technical depth, not headcount. We're looking for someone who is expert at both performance marketing and creative development — the person who sets up the creative and UA systems the AI runs on, decides what "good" looks like, and solves the hard problems that don't have a playbook yet. You own strategy end-to-end, without a middle-management layer above you, and you use AI agents to turn that strategy into performance at scale. WHAT YOU WILL DO - Set the creative and UA strategy: define the angles, frameworks, and testing approach that drive results across app/game titles. - Build the creative pipeline and workflows that AI agents run on — the logic, briefs, and quality standard behind them. - Take on the hardest data problems: work out why performance drops, decide what to change, and turn funnel data (CTR, CR, CPM, CPI, ROAS...) into action. - Come up with new creative concepts and content directions from market, competitor, and data insight. - Own creative testing end-to-end: set the hypotheses, structure the tests, read the results, and turn wins into repeatable patterns. - Run UA across major ad platforms (Applovin, Google Ads, Meta, TikTok, Mintegral, Affiliate, etc.), going deep on targeting, bidding, and scaling. - Set how people and AI work together in the creative-to-campaign loop, and raise the team's technical level through the systems you build. • Ngày làm việc: • Cấp bậc: • Loại công việc:
