ASO Specialist

At Breinton, we know the F2P market inside out — driving performance where it counts.

Location: Remote

Compensation & Employment Type: 15,000–21,500 PLN/month (B2B contract), depending on seniority.

ABOUT BREINTON

Breinton is a performance-driven user acquisition agency helping mobile games scale profitable player growth. We were founded by industry veterans who recognised a key challenge in mobile gaming: even the best releases can struggle if they don't reach the right players at scale. Today, we partner with studios worldwide to help high-potential titles compete at the top of the charts.

THE ROLE

We're looking for someone to own App Store Optimization for our portfolio end to end — from strategy down to the day-to-day test plan — and to bring dedicated focus to a function that's ready to be built out further, including a backlog of creative tests ready for direction.

This is fundamentally an analyst and planner role, not a design role. You don't need to be able to design an icon or a screenshot yourself — you need to be able to read the store and ranking data, form a clear hypothesis, and write a brief sharp enough that our designers can execute against it without back-and-forth.

If you happen to be both a sharp analyst/planner and a genuinely strong visual designer, that's a 12/10 for us — but it's not what we're requiring. We'd rather hire an excellent analyst who can brief a designer well than hold out for someone who does both.

WHAT YOU'LL DO

• Own ASO strategy end to end across the App Store and Google Play for the full game portfolio.
• Lead keyword research and metadata/store-listing optimization across markets and languages.
• Plan and prioritize icon, screenshot, and video creative tests, and write clear briefs for the design team to execute.
• Design, run, and analyze A/B tests (icons, screenshots, video, metadata), and turn results into the next round of hypotheses.
• Track rankings, impressions, installs, and conversion rate; report on performance on a regular cadence.
• Partner with User Acquisition, product, and design leads to align ASO work with launch and live-ops calendars.
• Select and manage ASO tooling (e.g., AppTweak, Sensor Tower, data.ai) as needed.
• Stay current on App Store and Google Play algorithm changes and ASO best practice.

WHAT WE'RE LOOKING FOR

• 2-3+ years in ASO or a related analytics/growth role — though what you've shipped matters more to us than the number itself.
• Experience owning ASO for at least one mobile app or game portfolio, in-house or agency-side.
• Strong analytical skills — comfortable working with ranking, conversion, and funnel data to make decisions.
• A proven track record of briefing and directing designers, without needing to produce the creative yourself.
• Working knowledge of ASO tooling and app-store A/B testing platforms.
• Comfortable working with LLMs/AI tools to speed up research, briefs, and reporting.
• Clear, concise written communication — we favor open, async-friendly channels over closed threads and status meetings.
• Self-directed: able to prioritize and move a backlog forward with limited day-to-day oversight.

NICE TO HAVE

• Genuine design skill on top of the analytical core — icons, screenshots, video. The 12/10 unicorn hire, not a requirement.
• Experience with idle, tycoon, or simulation mobile games specifically.
• Multi-market, multi-language ASO experience (20+ languages).
• An SEO background.
