Project Summary

We are looking for a Senior UX/UI Designer / Senior Product Designer to design GenAI products end-to-end, from business and user needs to polished, testable prototypes. Products target both knowledge workers and operational users, and technical users such as developers. The environment is fast-paced, access to end users can be limited, and the designer may switch between projects.

Main Responsibilities

• Translate business and user needs into tangible UX/UI solutions

• Design digital products end-to-end, with hands-on UI and interaction design

• Turn requirements into testable, reasonably polished prototypes quickly

• Work with incomplete information: document assumptions, reduce scope and prioritise value

• Collaborate with Product Owners, developers and domain experts, making pragmatic UX/UI trade-offs within technical constraints

• Onboard onto unfamiliar products and leave well-organised Figma files, decisions, assumptions and documentation for handover
