Game Systems Designer, Clash of Clans - Supercell Oy

Clash of Clans is our biggest and longest-running live game and after more than a decade, we're still asking what it can become. We're looking for a Game Systems Designer to join a Clash feature team focused on zero-to-one: new systems, progression loops, and player experiences built from a blank page rather than iterations on what's already live. You'll take open-ended questions; “How do we make a player's first hour unmissable? How do we make progression feel rewarding rather than like a wall?” and turn them into concrete, shippable design. You need real conviction about what works for Clash's current players, while exploring how Clash becomes relevant and attractive to audiences who've never played it. Holding both at once, without breaking faith with either, is the heart of the job. This is a role in equal parts quantitative and creative. The best ideas here are imaginative and survive contact with data. You should be as comfortable sketching a bold new system as you are reading a retention curve, designing an A/B test, and reading what it tells you. At Supercell, the best games come from small, independent teams with full creative freedom and real accountability, we call them cells. We greenlight teams, not ideas, and we default to trust over control. That means you'll own your work end-to-end, make the calls closest to the player yourself, and own the outcome, the wins and the misses both. Our quality bar is extraordinarily high. We shoot for the moon, and when something isn't reaching it, we have the courage to kill it and start over and we celebrate the attempt, because the only real failure is to stop taking risks. We pair that ambition with humility: we give and ask for direct, constructive feedback, because clear is kind, and we stay curious in the belief that however good the work is today, it can be better tomorrow. Players and Supercell first, team second, ego last. You’ll be doing design of new systems and player journeys end-to-end, from a blank page through concept, design, live release, and iteration. This could include progression systems, onboarding experiences, re-engagement flows, rewards, and other core parts of the player experience. You will tackle the hard player journeys: new-user onboarding, re-engagement flows for lapsed players, funnel optimization, and progression systems that feel genuinely rewarding to advance through. You will hold both audiences at once, designing that serves Clash's existing players while opening doors for players who've never touched the game. You will balance creativity with data, form hypotheses, design experiments, run A/B tests, and interpret live performance, player feedback, and community insight. You will own the player-first vision for your work, synthesizing community, creator, analytics, and team signals into experiences that fit the whole game rather than bolt onto it. You will drive execution with autonomy, push your work forward with minimal hand-holding, and bring the team with you. You have strong systems design experience, ideally on a live game, with experience on progression systems, player motivation loops, rewards, economies, onboarding, retention, or other systems that shape how players engage with a game over time. You have a genuine player-first mindset, comfort with analytics and A/B testing, and the ability to turn ambiguous problems into concrete design proposals. You have excellent communication and collaboration skills, a proactive sense of ownership, an eye for detail, and humility to kill your own good ideas when data or player feedback suggests so. You have a passion for games and a real appreciation for mobile. Background in progression systems, game economies, and long-term player motivation, experience designing new-user flows, re-engagement flows, funnel optimization, or progression revamps, and love Clash of Clans or are excited to fall in love with it are a plus. The role is based in Helsinki or London, with travel expected between offices. We support relocation from anywhere. We value applications from candidates with great skills and experience, even if they second-guess themselves. We are committed to diversity and inclusion. Apply through the form on the page.
