About Crossian

Crossian is a high-growth, technology-driven e-commerce business. Behind our success is our people. Founded in 2020, we have built a fast-paced and dynamic environment that enabled a cumulative average growth rate of over 1000% in under 3 years. Our mission now is to build global direct-to-consumer brands and increase customer lifetime value.

About the Role

• We are looking for an experienced Digital Growth Manager (AppLovin and similar networks) to own and scale user acquisition for our global e-commerce mobile app across AppLovin, Google and other ad networks. This is a leadership role: you will set the UA strategy, own the budget and growth targets, build and lead a high-performing team, and shape how our people work alongside AI to acquire users more efficiently than our competitors.
• You will be accountable for the business outcome, not just the campaigns: growing the paying user base profitably, improving ROAS and LTV, and turning data into decisions that the wider business can act on.

What You Will Do

Strategy & Business Ownership

• Define and own the UA and performance marketing strategy for the mobile app, with AppLovin as a core channel alongside Unity, Mintegral, Google (UAC/App campaigns)
• Own channel budget allocation, growth targets and P&L-level KPIs (CPI, ROAS, CAC, LTV, payback period, retention), and forecast performance for leadership.
• Identify new channels, inventory sources and growth levers; build the business case and lead their launch and scale-up.

Team Leadership

• Build, lead and develop a team of Applovin, setting goals, coaching, reviewing performance and growing future leaders.
• Design team structure, workflows and playbooks so the team scales without losing speed or quality.
• Hire and onboard talent together with the TA team, raising the bar for performance marketing at Crossian.

Human <> AI Performance Operations

• Lead the adoption of AI and automation across the UA workflow: bidding, budget pacing, creative testing, reporting and insight generation.
• Define where AI accelerates the team and where human judgment stays essential, and measure the productivity and performance impact.

Optimization, Measurement & Insight

• Set the testing roadmap across creatives, audiences, placements and bidding strategies, ensuring experiments are rigorous and learnings are shared.
• Oversee cohort analysis, LTV modeling and attribution (AppsFlyer, Adjust, Singular, SKAdNetwork) to guide investment decisions.
• Present regular performance reviews and strategic recommendations to senior leadership.

Cross-functional & Partner Management

• Partner closely with Creative, Content, Data/Analytics, technology teams to align on goals, creative pipeline and the in-app funnel.
• Own strategic relationships with AppLovin and other network partners, including account reviews, beta access and negotiations.
• Stay ahead of industry trends, algorithm and privacy changes, and translate them into action for the team.

What We Are Looking For

Education

• Bachelor's degree or higher in Marketing, Finance, Business, Economics, Data/Analytics, Computer Science or a related quantitative field, Preferred: graduated from a reputable overseas university.
• 8+ years of experience in performance marketing / growth, including 3+ years of hands-on mobile app user acquisition on AppLovin or similar networks (Unity, Mintegral, Google UAC).
• Proven track record of owning and scaling large UA budgets profitably, with clear results on ROAS, LTV and payback.
• Experience in global, multi-market campaigns; e-commerce, D2C or consumer app experience is a strong plus.
• Excellent communication and presentation skills
• Ability to work autonomously and manage multiple projects simultaneously
