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.

About the role

This is a junior position. You don't need years of mobile UA experience. You need the right foundation - strong marketing knowledge, real curiosity, analytical instinct, active AI use, and a creative eye - and we'll build the rest together.

You’ll join the 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 energised 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.

What you'll do

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 optimise 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.

What we are looking for

• 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.

What we are not looking for

If you’re applying because the role sounds exciting but you haven’t looked up what CPI means, haven’t downloaded the app, and haven’t done anything to bridge the gap between where you are and what this role needs — this probably isn’t the right moment. The role is genuinely junior, the expectation is that you’re already moving toward it.

What 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!
