About UserWise

We're building a high-speed, AI-assisted game production team focused on developing and scaling mobile games globally.

This is not a traditional game team. We operate with ownership, clarity, and execution speed, leveraging AI-driven workflows to move faster than most studios.

We work across a integral team, building production-ready games and scaling them through LiveOps. Our focus is simple: increase the number of high-quality bets and turn them into scalable products.

Our team has already worked across established franchises such as Fruit Ninja and Wordscapes, contributing to both development and growth initiatives.

The Role

We're looking for a senior game designer with strong product management understanding to help us identify, build, validate, and scale new game products.

This is a product builder role. You'll work closely with our Chief AI Officer, combining strong game design, product thinking, data, and AI-assisted workflows to turn opportunities into playable products quickly.

You'll own the what and why behind the product,



while staying close enough to the work to turn ideas into prototypes, tests, and production-ready games.

What You'll Do

• Identify and evaluate new game opportunities through market analysis, competitor deconstruction, player insights, and product data
• Turn opportunities into clear product bets, defining the concept, target audience, core loop, product hypothesis, success metrics, and commercial opportunity
• Own AI-assisted game design across core loops, systems, progression, economy, UX, retention, and monetization
• Rapidly prototype and validate game concepts using AI-assisted tools and lightweight development workflows
• Define success metrics, analyze player behavior and test results, and make clear recommendations on whether to scale, iterate, or kill
• Own product priorities and make trade-offs based on player impact, data, development effort, and business potential
• Continuously improve games based on
