Technical Artist

You’ll be the in-house designer responsible for the look, feel and motion of our digital game products - both in-game and UI, with occasional web and marketing asset work. You’ll own the visual design of game UI from concept to delivery, working closely with our developers to produce polished, on‑brand experiences across mobile, tablet and TV.

In-Game Assets

• Design game assets for Unity titles
• Create UI assets production-ready for Unity’s uGUI system: sprite sheets, atlases, UI components, and screen layouts
• Design stylised assets in line with game art direction, including toon/flat aesthetics consistent with FlatKit and similar rendering styles
• Produce assets that work across the Universal Render Pipeline (URP), including any overlay or focus effects
• QA your own work in Unity - verifying assets render correctly, checking layout at target resolutions, and flagging integration issues to the developer
• Collaborate with the Game Developer on shader-driven UI effects and stencil-based UI overlays where required

Flutter App UI Design

• Design screens, components and flows in Figma, ready for Flutter implementation
• Maintain and evolve app design systems - components, tokens, spacing, typography and colour
• Design for Android and iOS - respecting platform conventions while maintaining a consistent Big Potato visual identity
• Work with the Full Stack Developer to ensure Figma handoff is clean, annotated and implementation-ready

Motion & Animation

• Design and deliver motion for both Unity and Flutter surfaces: UI transitions, button states, loading sequences, celebration moments and FTUE flows
• Produce After Effects or Lottie animations for Flutter, and Unity Timeline‑compatible animation briefs for game UI
• Bring energy and polish to key moments in the product - onboarding, game launch, win/lose states

Cross-Product Design Consistency

• Maintain visual coherence across all digital products
• Own and evolve the digital design system, ensuring reusable components are well‑documented in Figma
• Work with the Head of Digital and PM to understand product goals and translate them into considered design solutions

Production & Delivery

• Deliver assets to spec and on time, adapting to sprint cycles and game launch schedules
• Reduce reliance on freelance design resource by being the reliable in‑house owner of design output
• Use AI design tools to increase throughput without compromising quality
• Maximize asset efficiency to ensure builds are as snappy as can be.

What success looks like

• Freelance design dependency is materially reduced within six months
• Game UI assets are delivered to Unity spec with minimal rework from the developer
• Motion design is a consistent, valued part of product releases - not an afterthought
• App design system is coherent, documented and used consistently
• Design is never the bottleneck in a sprint
• The team has a designer they trust to own work end-to-end within scope

We’re committed to building a team that reflects a wide variety of backgrounds and perspectives, and we encourage applications from underrepresented groups.

Essential

• Strong UI design portfolio demonstrating work across mobile apps and/or games
• Proficiency in Figma - components, auto layout, variables/tokens, and developer handoff
• Experience designing UI assets for Unity (uGUI) - understanding of sprite atlases, canvas scaling, and asset export requirements
• Ability to QA your own work in Unity: verify renders, check resolutions, identify integration issues
• Motion design skills - you can independently deliver UI animations, transitions, and micro‑interactions (After Effects, Lottie, or equivalent)
• Experience designing for both Android and iOS, respecting platform conventions
• Comfortable working within an established visual style and game art direction
• Organised, self‑directed, and able to manage your own workload within sprint cycles

Desirable

• Experience designing stylised / toon UI - flat design aesthetics, bold outlines, expressive colour
• Familiarity with Unity’s Universal Render Pipeline (URP) and how it affects UI asset requirements
• Experience with shader‑driven UI effects (stencil buffers, focus/overlay, custom UI shaders)
• Flutter/Dart design system experience - understanding how Flutter renders components
• Unity Timeline familiarity - ability to brief or contribute to animation sequences
• Experience designing FTUE (First Time User Experience) and onboarding flows
• Exposure to WebGL UI - understanding of resolution constraints and browser rendering
• Experience at a games studio or on consumer entertainment products
• Familiarity with Lottie for cross‑platform animation delivery
• Use of AI design tools to accelerate production

Working Style

• Takes ownership of their work and sees it through to a polished finish
• Is comfortable working across multiple products and surfaces simultaneously
• Collaborates closely with developers and understands technical constraints
• Has strong visual taste and can articulate design decisions clearly
• Is energised by games and understands what makes a digital play experience feel good
• Is excited about using AI to increase output without sacrificing craft

We’re currently growing our digital team, so the process may take a little longer - but we’ll keep you updated throughout.
