About the role

Key responsibilities & impact

Design autonomously. You’ll define and drive design work from scratch - identifying what needs to be done while raising the quality bar.
Simple interfaces. Design products that solve problems in a simple and elegant way while taking care of every small detail, from wire-framing to designing end-to-end flows and prototypes.
Design for clarity and depth. Your job is to make powerful tools feel accessible, intuitive, and engaging across various categories.
Prototype quickly and test ideas. You’ll use tools like Figma, Cursor, and light code to explore concepts, validate assumptions, and refine interfaces based on real feedback.
Develop insights through research. Talk to users, analyse behaviour, and extract meaningful patterns that inform product direction.
Enhance our design system for both of our products. Redefine the standards and systems that keep our products cohesive.
Act as a force-multiplier. Raise the bar - not just through your own work, but by modeling great thinking, process, and collaboration across the company.
