Ux / UI Designer in City of London

We are seeking a mid-Level UX / UI designer with a strong portfolio of work on digital products and services to join our client - a leading telecommunications company. The successful candidate will be responsible for producing high-quality design deliverables for both web and mobile services (Android & iOS), playing a crucial role in the visual design and user experience of our products.

The UX / UI designer role is situated within a London team, part of a larger department consisting of around 160 UX and design professionals located across five sites in France, plus London.

The role requires a good grasp of the end-to-end design processes, starting from requirements capture, ideation, developing concepts, sketching, prototyping and producing final deliverables. The role is focussed on UX / UI production and expected to prepare and perform the relevant design activities at each phase of a project, such as wireframing, prototyping, asset production, UI hand-off, etc. The UX / UI role will need to develop detailed knowledge of design system components and the guidance for their usage. The role is likely to involve working with user researchers, which requires understanding the role and purpose of user research and how insights are integrated in the design process. The role requires familiarity with and observation of ethical and inclusive design practices, including accessibility recommendations (e.g., W3C WAI and WCAG). Communication skills and stakeholder relationship management are important aspects of the role for design delivery. The UX / UI designer needs to be confident presenting design proposals, defending decisions and communicating design value to non-specialist audiences. Designers generally participate in multi-disciplinary teams involving researchers, developers, product owners, and other contributors. Different project methodologies coexist, but Agile frameworks are widely adopted, and the design role should be comfortable providing design advocacy in these environments.
