You do not need to be an engineer, but you know why a design that is trivial in native mobile might be expensive in Unity or Unreal, and you design accordingly * Solid design and prototyping skills across modern tooling - Figma is required - with fluency in AI-assisted design and prototyping workflows (e.g. prompt-to-prototype or code-based prototyping tools); Our stack is still being defined, and we expect you to help define it * Excellent communication skills, with the ability to socialise research findings and articulate design decisions to internal teams, engineers and leadership * Comfort operating in early-stage environments where research practices and design standards are still being defined, * Experience designing for children in regulated digital environments * Experience building a mobile design system for a platform team, where multiple teams consume it * Experience designing embedded UI (overlays, webviews, native modules) that lives inside other applications * Familiarity with common engagement and monetization patterns in live digital products * Experience with localization and designing for global audiences * Working knowledge of mobile accessibility guidelines (WCAG, platform-specific standards) * A genuine love of games - you play on mobile and have opinions about what great platform UX feels like. ## Description This is a newly created role based in London; this is an individual contributor role reporting to the Senior Director, Product. Key Responsibilities * Partner in player research: plan studies, synthesise findings, and turn insights into design direction the whole team can act on * Own the UX for player-facing platform features on mobile - flows, wireframes, prototypes, and UI specs - grounded in evidence from research at every stage. * Research and design for a general audience spanning kids, parents, and adult fans - age-appropriate, safe by default, and delightfully playful for everyone * Use analytics, funnel data, and A/B testing alongside qualitative research to identify friction, propose improvements, and measure the impact of shipped work * Design mobile-first experiences that adapt gracefully across screen sizes, aspect ratios, notches, foldables, and both portrait and landscape orientations * Build a component design system that internal teams consume as a shared tool: components, patterns, and guidance that serve players of every age * Champion accessibility and inclusive design across the platform, meeting or exceeding mobile accessibility standards * Collaborate closely with product managers, internal teams, and platform engineers to balance player needs, team needs, and technical realities ## Related Videos - [Boost Productivity with AI: Figma & Playwright MCP Workflows - Aris Markogiannakis](https://www.wearedevelopers.com/videos/1768-boost-productivity-with-ai-figma-playwright-mcp-workflows-aris-markogiannakis) - [Xcode development redefAIned](https://www.wearedevelopers.com/videos/100195-xcode-development-redefained) - [Bringing the power of AI to your application.](https://www.wearedevelopers.com/videos/1010-bringing-the-power-of-ai-to-your-application) - [UX is a fullstack job!](https://www.wearedevelopers.com/videos/1020-ux-is-a-fullstack-job) - [Designing the Future of Human<>Agent Collaboration](https://www.wearedevelopers.com/videos/1447-designing-the-future-of-human-agent-collaboration) - [Beyond Autocomplete: Local AI Code Completion Demystified](https://www.wearedevelopers.com/videos/961-beyond-autocomplete-local-ai-code-completion-demystified) ## Related Articles - [Dev Digest 118 - not a total recall](https://www.wearedevelopers.com/magazine/452-dev-digest-118-not-a-total-recall) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [The future is here: How artificial intelligence is influencing UX design](https://www.wearedevelopers.com/magazine/65-the-future-is-here-how-artificial-intelligence-is-influencing-ux-design) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Top 5 Web Design Trends for 2023](https://www.wearedevelopers.com/magazine/155-top-5-web-design-trends-for-2023) - [Dev Digest 119 - ❤️ === ❤️](https://www.wearedevelopers.com/magazine/454-dev-digest-119)
