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, AI agents handle a lot of the day-to-day running and coordination in performance marketing. That changes what we need from people. This isn't a role about managing a team — it's about being the strongest technical and creative person on it. We're looking for someone who is expert at both performance marketing and creative development: you set up the creative and UA systems the AI runs on, decide what good looks like, and solve the hard problems that don't have a playbook yet.
Working Place
- Ha Noi: 1st Floor, Pax Sky Building, 63-65 Ngo Thi Nham Street, Hai Ba Trung District
- Ho Chi Minh: Floor 12, Diamond Plaza, 34 Le Duan, Ben Nghe Ward, Ho Chi Minh City
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 — not just variations of what already works
- 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
WHAT WE ARE LOOKING FOR
- 5+ years of strong, proven experience in both performance marketing / UA and creative development for mobile apps/games
- Background at a Top-tier Tech/E-commerce or gaming company
- Expert with ad platforms, performance metrics, and tracking/attribution
- Expert in creative development: content components, brief and content-flow design, and building new angles from insight
- Experience building or working closely with AI-driven marketing workflows or agents
- Systems thinking: you build repeatable, scalable processes, not one-off outputs
- Strong analytical and problem-solving skills; fluent English (written and spoken)
- Always testing, learning, and improving
