Coin Master is Moon Active’s flagship game and one of the most successful mobile games in the world, with 300M+ downloads and 6M+ daily players. Our Kyiv office is one of Moon Active’s key development centers.
Behind a casual-looking game sits serious engineering: microservices, real-time social features for millions of players and a live product that changes every week. It’s a mature product with well-run processes, built by some of the strongest engineers and product people in mobile gaming, with a huge amount of data to learn from.
Unity doesn’t have to be your main stack. We’re looking for strong engineers who see new technology as motivation, not an obstacle. If you’ve been exploring Unity through pet projects, game jams or courses, we’d love to hear from you, whether you’re experienced or earlier in your career with solid fundamentals.
AI is at the core of how we work. For us, it goes far beyond Claude Code or Cursor: we constantly look for new tools, test them and bring the best ones back to the team.
What you’ll do
Build client-side features for Coin Master end to end, from technical design to production release.
Design clean, maintainable Unity architecture for a game played by millions of people every day.
Make AI part of every stage of your work, and help the team find and adopt new tools, building AI flows and ways of working.
Use data to investigate production issues and improve performance across a wide range of devices.
Integrate native plugins and third-party services.
What we’re looking for
Commercial software development experience and strong engineering fundamentals: design patterns, algorithms, data structures and memory management.
Hands-on experience with Unity, from commercial work or your own projects. Show us what you’ve built.
Real, everyday experience with AI tools: you use Claude Code, Cursor or similar in your work, keep track of new tools and enjoy experimenting with them.
English good enough to go through technical interviews and work with colleagues in Tel Aviv.
A genuine interest in games and in how they’re built.
Curiosity, ownership and clear communication.
Nice to have
Experience with mobile development.
Experience with analytics and data-driven development.
Experience building AI-driven tools, agents or automated workflows.
Our Kyiv office
Our office is a big part of who we are. It has its own atmosphere, a close-knit team and a real sense of community, and we love spending time there together. It’s fully equipped to keep working during power outages. We work in a hybrid format and would love for you to join us in the office when you can, while staying flexible given the current situation.
What we offer
We offer paid vacation, additional days off, including leave for important life events, and sick leave, and we follow the Ukrainian holiday calendar. You’ll get premium medical insurance for yourself and your family, reimbursement for sports, English courses and a personal learning budget for courses, conferences and workshops. We’re happy to walk you through all the details during the interview.
