Senior Interaction Designer

Applications for this position close on 25th October 2026 - 23.59pm UK Time

Incubator for AI, i.AI

Help shape how people interact with some of the most ambitious AI products in government

At i.AI, you will help design the interactions, flows and interfaces behind frontier AI products being developed for real public services. Your work will shape how emerging technologies are used to solve real problems for real users - in ways that are useful, trusted, accessible and grounded in evidence.

You will join a multidisciplinary team working at the cutting edge of AI delivery in government. This is an environment for designers who want to tackle hard questions, work through ambiguity, influence product direction early, and help ensure teams build the right things in the right way.

This is a rare opportunity to work on some of the most important and fast-moving questions in government: how AI can be turned into practical tools that improve public services, while staying focused on user needs, ethical considerations and measurable impact.

At i.AI, we do not explore technology for its own sake. We work quickly to understand whether there is genuine value in a problem area by building working products, putting them in front of users, and learning from what happens next. Design is central to that process.

If you are excited by difficult questions, fast feedback loops, and the chance to improve public services through evidence-led design, this is an opportunity to make a genuine impact.

About the role

Interaction Designers work within agile teams to design interaction flows and product interfaces that meet our standards for usability, branding and accessibility. Their work helps teams deliver better products and services, reduce cost and risk, and continuously improve based on evidence. 

This is a rare opportunity to work on some of the most important and fast-moving questions in government: how emerging AI technologies can be used to solve real problems for real users, in ways that are useful, trusted and grounded in evidence. 

You will work in one of our multidisciplinary product teams, each focused on a different application of AI to a government problem space - for example planning, education, government operations or frontline services. Our goal is not to explore technology for its own sake. We work quickly to understand whether there is genuine value in a problem area by building working products, putting them in front of users, and measuring real impact. 

i.AI is an incubator, which means our teams are small, nimble and optimised for learning fast. You will need to be flexible, comfortable with ambiguity, and motivated by turning insight into action. In return, you will have the chance to shape products at an early stage, influence strategic decisions, and ensure teams stay focused on the needs, behaviours and realities of the people they are trying to serve. 

If you are excited by difficult questions, fast feedback loops, and the chance to improve public services through evidence-led design, this is an opportunity to make a genuine impact. 

What you will work on

• Deliver high-quality, user-centred designs as part of a multidisciplinary team
• Use evidence to challenge assumptions, validate decisions and negotiate with stakeholders
• Build ethical review and evaluation into your work to reduce unintended consequences
• Develop patterns for how people interact with AI, working with teams across i.AI and beyond
• Lead good design practice, including line managing junior designers
• Contribute to i.AI's design community and to GDS and cross-government design communities
• Foster an inclusive team culture built on honest feedback and continuous improvement

• Has a track record in user-centred digital product design in a product-led organisation, and knows which tool or method suits the job
• Is proficient across a range of design and prototyping tools, including HTML prototyping (AI-assisted is fine)
• Collaborates well in multidisciplinary teams, iterates designs using data, research and best practice, and builds strong working relationships with colleagues and stakeholders
• Communicates clearly and persuasively, bringing clarity and alignment across project and leadership teams, especially when things are ambiguous
• Reflects critically and asks difficult questions, seeing the big picture and its wider implications while staying focused on the minimum viable product
• Contributes to the wider design community, for example by speaking at meetups or writing blog posts
