As a Game Designer, you will design, tweak, and optimize the player experience. Your analytical skills, player insight, and creativity aid in crafting in- and out-of-game experiences that engage and surprise players. You will collaborate with interdisciplinary teams and work with every tool at hand to innovate and iterate player-focused designs that'll delight millions around the world.

As a Game Designer III specializing in AI you will build and iterate on the core foundations of our AI. Creating believable and readable AI characters that present challenging and exciting combat puzzles for the player to solve is the key area of focus for this role. A strong core AI foundation will be the bedrock for a huge variety of interesting enemies, allies, and encounters. We are still small, so this requires plenty of hands-on work creating, iterating, and tuning levels and mechanics. You are comfortable operating in an ambiguous environment where goals and constraints are mostly team driven and where change, big and small, is a critical part of the process. You will report to the Combat Design Lead on the team.
