Job description

About the Role

We are looking for an HTML Developer with a strong interest in gamification and interactive experiences to help build engaging, responsive, and dynamic user interfaces for game-driven products. This role focuses on translating briefs for game mechanics and design concepts into polished, performant front-end experiences.

You will work closely with designers, UX/UI designers, and engineers to implement gamification elements such as progress states, rewards, animations, transitions, and interactive feedback systems.

This is a hands-on role for someone who enjoys turning mechanics into clear, satisfying player experiences.

Key Responsibilities

• Build and maintain interactive, game-like UI components using HTML, CSS, and JavaScript for a mobile first environment
• Implement gamification elements such as:
• Progress indicators and meters
• Persistent states (e.g. collected items, activated features)
• Animations, transitions, and visual feedback
• Reward and unlock sequences
• Translate UI and interaction designs into high-quality, responsive layouts
• Work with designers to refine timing, motion, and visual clarity of interactive elements
• Understand and comprehend CMS systems to facilitate the building of the gamification
• Ensure interfaces perform smoothly across all platforms and devices
• Maintain clean, modular, and reusable front-end code
• Debug and optimise interactive elements for performance and stability

Required Skills & Experience

• Strong proficiency in HTML5, CSS3, and JavaScript (ES6+)
• Experience building interactive UI components, not just static pages
• Solid understanding of CSS animations, transitions, and transforms
• Familiarity with managing UI state and dynamic updates
• Experience with responsive design and mobile-first development
• Ability to work accurately from design mockups and interaction specs
• Comfortable collaborating in a multidisciplinary team environment

Nice to Have

• Experience working on games, gamified products, or interactive media
• Familiarity with canvas, SVG animations, or lightweight animation libraries
• Experience with frameworks or tooling (e.g. React, Vue, or similar)
• Understanding of game UX principles (player feedback, anticipation, reward timing)
• Interest in game mechanics, player psychology, or interactive storytelling

What We’re Looking For

• Someone who thinks in states, progression, and feedback, not just layouts
• Attention to detail in motion, timing, and visual clarity
• A problem-solver who can suggest improvements to interaction flow
• Passion for building experiences that feel responsive, rewarding, and intuitive
• A can-do attitude that allows for context switching from gamification to other player-centric design elements when required
