• Using data to inform and balance existing content and form hypotheses and direction for future content.
• Assisting the level design team with improving our content pipeline and processes.
• Supporting and collaborating with the wider team in their disciplines from a level design perspective (Production, QA, RND, Art, etc).

Requirements

• A passion for gaming, particularly casual mobile games.
• A solid grasp of design methodologies and an up-to-date knowledge of the casual mobile audience, casual game markets and player motivations.
• Proficiency in Unity (Unreal or similar acceptable), including scripting (C# preferred).
• Hands‑on experience with automation and AI‑powered tooling to streamline design workflows (e.g. scripting, web tooling / HTML, LLM‑based tools).
• Ability to analyse player data, specifically engagement/monetisation/performance metrics, and to make informed decisions regarding status and any needed changes.

Advantages

• Experience in mobile game design/QA/development or similar field.
• A Game Design (or similar) degree.
• Experience building design or production pipelines/tooling at scale.
• Experience mentoring or upskilling designers on technical practices.
