About the Role

As a Senior UX Designer, you will be a champion for user experience, leading the definition and delivery of digital products that are grounded in deep user understanding and evidence‐based decision‐making.

From planning and conducting research, framing problems, and defining experience strategy, through to validating and refining solutions, you’ll ensure our products are intuitive, inclusive, and impactful.

This role is ideal for a designer who is comfortable working upstream in discovery, confident leading research activities, and passionate about turning insight into meaningful experiences.
