About
We aim to create a world where sending and receiving money is effortless. Our app allows users to pay people, not numbers - no IBAN, account numbers, or sort code required. All you need is the recipient's name to send money. Sling leverages blockchain technology to transfer in any currency almost instantaneously for a negligible fee. We’re in 150 countries and the app is available in the Android and iOS app stores. Sling is from Avian Labs, Inc., created by product builders and engineers from Monzo, Square, and Cash App. About the role

to help shape the future of Sling Money. You’ll be the second designer on the team, working directly with Simon Amor (co-founder and designer) across product, design, and strategy. This is a hands-on role with high impact — your design decisions will shape a product used around the world. You’ll be simplifying complex problems in a way that communicates ideas clearly, and designing solutions that feel effortless for users, no matter how intricate the problem. Through close collaboration with product and engineering, you’ll craft experiences that are intuitive, elegant, and deeply user-focused. You’ll bring a sharp eye for visual design and a strong sense of craft, with the ability to balance detail and speed. You'll create a truly global product with consideration for internationalization challenges across all surfaces. And as one of the first designers at Sling Money, you’ll define not just the product, but the design culture as a whole. Beyond product, you’ll also contribute to brand and marketing design, helping shape how Sling Money shows up in the world. From launch campaigns to landing pages, you’ll work on creating a visual language that’s consistent, expressive, and clear. We’re looking for someone who can bring the same level of craft and simplicity to external touchpoints as they do to the product itself. Design at Sling Money
