About the role

Key responsibilities & impact

Own the product design of a consumer entertainment app heading into global launch — from concept to shipped feature.
Design the systems that make the product feel alive: relationship progression, character profiles, gamification, notifications and re-engagement, monetization.
Prototype, test, and iterate quickly — you're not just pushing pixels; you're designing how a product communicates warmth, care, and personality.
Transform research insights, analytics, feedback, and user testing into concepts and interactive prototypes.
Design detailed workflows, high-quality mockups, and intuitive mobile-first interfaces.
Work side-by-side with engineers to perfect implementation.
Build and maintain a cohesive design system across mobile, desktop, and web.
Jump into brand visuals and marketing when needed — we love designers who go beyond the screen.

Requirements

What you’ll need

4+ years of experience in product design with a portfolio that proves it — ideally including consumer mobile products.
Experience working on live products at scale (millions of users/installs) — you understand real user behaviour, funnels, and how design decisions play out in metrics.
Experience designing for global audiences (US, Asia, or other international markets) — you understand how visual language and product patterns differ across cultures.
A genuine interest in entertainment, gaming, social, or companion-type products — and fluency in contemporary internet culture, anime/gaming aesthetics, or fandom communities is a big plus.
Fluency with modern AI tools (image/video generation, AI-assisted design workflows) — or strong curiosity and willingness to learn fast. We use them daily as accelerators, but we hire people who think for themselves.
A flexible, fast-iterating mindset: you'd rather ship three quick iterations and learn than polish one concept in isolation.
Startup or early-stage experience is a plus — you can navigate ambiguity and adapt as the product evolves.
You communicate clearly — no ego, no drama, just great ideas and collaboration.
You believe in simple, elegant solutions — complexity is the enemy of great design.
English proficiency (minimum B1) to collaborate effectively with the team, plus conversational skills in Russian, Ukrainian, or Belarusian, as these are currently our primary internal languages.
