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 retention, engagement, monetization, experimentation, and player behavior
  • Partner closely with leadership to evolve how AI is used to design, prototype, build, and scale games faster

Environment

  • High ownership: You own product decisions and outcomes
  • High speed: We build, test, ship, and iterate quickly
  • AI-assisted workflows: AI is embedded into how we design and build
  • Data-driven: Product decisions are informed by player behavior and measurable outcomes
  • Global team: Work across multiple regions and disciplines
  • Low bureaucracy: Minimal process, maximum execution
