-- Craft: Games Design mentor other designers and contribute to the broader design community.
Skills to create thrills Demonstrable, hands-on experience designing and balancing economies for merge games.
Experience on Merge 2 titles is strongly preferred, with a clear understanding of generators, merge chains, board pressure, energy loops, order systems, and progression pacing.
A record of owning or materially shaping economies on games in development and live operation, ideally in free-to-play mobile games with meaningful scale.
Deep understanding of how merge-game economy decisions affect player motivation, retention, session frequency, monetisation, content cadence, and the perceived fairness of the game.
Strong analytical capability and confidence building spreadsheet models, simulations, and practical tools to test assumptions and communicate outcomes.
Experience using product data and experimentation to balance systems, assess feature performance, and improve player journeys.
Excellent systems thinking: able to connect individual mechanics into a coherent whole, anticipate second-order effects, and simplify complexity for players and teammates.
Strong design judgement, written communication, and presentation skills, with the ability to create clear specifications and align varied senior perspectives.
A collaborative leadership style.
You are comfortable working across disciplines, giving constructive feedback, and creating momentum in an evolving development environment.




Genuine enthusiasm for free-to-play games, merge games, and the craft of building player-first economies.
Nice to Have Experience taking a merge game from concept or soft launch through live operation.
Experience with economy telemetry, SQL, BI tools, or scripting used to investigate player behaviour and validate economy hypotheses.
Experience designing live events, offers, segmentation strategies, or content frameworks for a merge title.
Experience mentoring designers or leading economy design across multiple features or teams.
Why This Role You will have the opportunity to establish the economic DNA of a new game and influence its direction at every level.
This role is idóneo for a principal designer who wants to combine deep merge-game expertise with creative leadership, rigorous analysis, and close collaboration to build an experience players will return to for years.
