We are seeking an experienced Senior UX Designer to shape the user experience of a Generative AI platform for a UK government department. This role focuses on making complex AI behaviour - retrieval, uncertainty, hallucination risk, and human-in-the-loop checkpoints - understandable and trustworthy for government users, while meeting GOV.UK Service Standard expectations., User Research & Discovery Conduct user research with internal government users and stakeholders to understand tasks, pain points, and trust concerns around AI-assisted workflows, feeding findings into design and product decisions. Interaction Design for AI Workflows Design end-to-end user journeys for RAG-based question-answering, agentic workflows, and human-in-the-loop review steps, ensuring users understand what the AI is doing, where information comes from, and when human judgement is required. Responsible AI UX Translate guardrails and human-in-the-loop checkpoints defined by policy/technical leads into clear, usable interface patterns (e.g. confidence indicators, source citations, escalation flows) - an execution and craft role, not a policy-setting one. Prototyping & Testing Produce wireframes, prototypes, and high-fidelity designs (e.g. in Figma); run usability testing sessions with real users and iterate designs based on findings and evaluation metrics from the engineering team. Design System Stewardship Ensure all designs align with, and where necessary extend, the GOV.UK Design System, maintaining consistency across the platform. Cross-Functional Collaboration Work closely with Product, UI Developers, and AI/Backend engineers to ensure designs are technically feasible and correctly implemented, and to align on evaluation-driven iteration.
