We're hiring a Senior Freelance Digital Product Designer to support a creative/digital agency on a short-term project focused on engaging, reward-driven digital experiences. This role is ideal for a designer with strong experience in mobile apps, gamification, loyalty apps, and repeat-visit product journeys.

You'll be designing products that users want to tap, scroll, and return to, with a clear emphasis on emotion, interaction, and craft.

The role
