Boom Castle runs 100,000 games a day. Every feature, every economy tweak, every A/B test generates data that either drives a decision or gets ignored. Your job: make sure nothing useful gets ignored. You’ll own analytics end-to-end – from instrumentation to recommendation – working closely with product, game design, and marketing. Eventually, you’ll build the data team around you.

What you’ll do:

• Own data analytics for Boom Castle – business, product, game economy, and monetisation
• Design and evaluate A/B tests on features, economy mechanics, and monetisation levers
• Analyse player behaviour, retention, and spend to inform product and design decisions
• Work with game design, development, and marketing as a collaborator, not a service desk
• Ensure data integrity across pipelines so decisions are built on trustworthy numbers
• Later: hire and lead the data team you’ll shape from scratch

What we’re looking for:

• 4+ years in data analytics – games or mobile apps experience is a strong plus
• Fluent in BigQuery, SQL, and at least one BI tool
• Experience running A/B tests, building forecasts, and presenting findings that change decisions
• Methodical about data quality – a broken source makes the insight worthless
• Clear communicator: your reports get read, not archived
• Based in Brno, or ready to relocate

What you get:

• Fair contract – employment or freelance, your call
• Modern office in downtown Brno
• Small team, serious experience – 19 people total, including you
• Managers who get it, and real flexibility
• Real input into where the company and our games are headed
• Full transparency – you’ll always know what’s going on
• Zero-bullshit policy
