Junior User Acquisition Manager

About the Position

Nanobit is a Zagreb-based mobile entertainment studio and part of Stillfront Group. For 15+ years we've built games and interactive stories played by tens of millions of people worldwide. We're now expanding into a new product category: short-form vertical drama for mobile audiences. We're building it with the same craft and audience focus that has defined our games.

We are looking for a Junior User Acquisition Manager to join our UA team working on ReelSaga, Nanobit’s short-form drama app (anime and live-action vertical series). The short drama category is new, the playbook is being written in real time, and we’re looking for someone energized by that, not someone who needs a fully defined role to thrive.

From day one you’ll work directly with the Marketing Team Lead on live campaigns. You’ll learn by doing - real budgets, real data, real consequences - and grow into owning channels and workstreams within your first six months.

Responsibilities

In the first 30 days

• Get fully up to speed on our active campaigns - structure, naming, creative logic, bid strategy, and why each decision was made.
• Run daily campaign checks: spend pacing, CPI, CTR, creative performance. Flag anomalies and ask questions.
• Learn how our attribution stack works - AppsFlyer, SKAN basics, UTM hygiene.
• Take ownership of at least one small test or reporting task end-to-end.

As you grow into the role

• Set up, manage, and optimize paid campaigns across Meta, TikTok, Google, and AppLovin.
• Run structured creative tests - hooks, openers, CTAs, formats - and feed clear learnings back to the creative team.
• Build and maintain dashboards tracking CPI, retention, ROAS D1/D7, and cohort LTV.
• Work with the web-to-app funnel - landing pages, attribution, deep linking - and learn how to measure and optimize the full chain.
• Use AI tools actively: for creative variation, audience research, reporting, brief writing, and anything else you can automate.
• Stay close to the product and content teams. UA doesn’t sit in isolation here.

Requirements

• Marketing fundamentals: You've worked in or studied marketing seriously enough to have opinions about what makes an ad or a campaign work. You think about why things work, not just whether they do.
• You've tried to understand how paid campaigns work - whether that's running something small yourself, doing a course, or just pulling apart an ad you saw and thinking about why it was built that way.
• Analytical comfort: You’re at home in a spreadsheet, you’ve tracked performance metrics before, and you think in cause-and-effect terms when you look at data.
• Active AI use in your current work. You don’t just use AI occasionally - it’s part of how you work. You’ve built something with it, even if it’s small.
• Creative literacy: You notice what makes an ad stop the scroll. You can write a brief. You have opinions about hooks, pacing, and CTAs.
• Bias for action. You’d rather test something today and learn than plan for a week.
• Fluent English

Nice to Have

• Any exposure to mobile apps, AppsFlyer, or SKAN - even from reading or a course.
• Experience with short-form video: TikTok, Reels, vertical content.
• Background in a performance-adjacent category: subscriptions, entertainment, gaming, DTC, or anything where you measured results rather than impressions.
• You’ve used ReelSaga, ReelShort, DramaBox, or a similar app and have opinions about what makes the format work.

We Offer

• A new product, a real budget, and the opportunity to test, automate and scale how UA runs from day one.
• Direct collaboration with the product, content and creative teams that ship the actual show - not just the marketing surface.
• Backing of Stillfront Group: cross-studio peer network, shared learnings, established marketing services and BI infrastructure.
• Additional financial benefits based on annual success, such as a Christmas bonus, Easter bonus, summer bonus, as well as referral bonuses and covered transportation expenses.
• Work-life balance: we are dedicated to our work, but also understand the importance of flexibility, switching off and recharging. Based on that, we offer flexible working hours and a hybrid work model, with office days mandatory from Tuesday to Thursday. Each one of our teammates enjoys an hour-long lunch break and 24 days of annual leave.
• We sponsor your monthly Multisport membership and offer you a free annual health check-up, healthy (and not so healthy) snacks, free lunch each day when working from the office and occasional discounts on various services and products.
• Parents, you are included too! We got your back with kindergarten compensation and soon-to-be parents can look forward to a baby bonus!
