Lead Product Designer – AI

The team you'll be working with:

Lead Product Designer (P3) – Ai driven

NTT DATA is a trusted global innovator with over 100,000 professionals in 50+ countries. Headquartered in Tokyo, we bring elements of our Japanese heritage—precision, long‑term thinking, and social responsibility—into our UK work. In the UK, we work across telecoms, financial services, manufacturing, and the public sector, delivering end‑to‑end services from strategy to implementation.

Tangity
, part of the NTT DATA Design Network, is a global design studio dedicated to humanising complexity. We combine Strategy, Technology, and Design to create meaningful, inclusive, and impactful services that improve lives and systems. Our studios work closely with delivery teams to embed design deeply into every project and across every touchpoint.

We are looking for a Lead Product Designer, who has experience in delivering AI products and services and has the ability to leverage AI tools in their design process.

This role sits within cross-functional product squads alongside Product Managers, Engineers, Data Scientists and AI specialists. You will help shape intelligent products from early concept through to scaled delivery, ensuring they are intuitive, transparent and grounded in real user needs.

You will combine strong product thinking, systems design and interaction craft with a practical understanding of how AI models behave in the real world, including their strengths, limitations and evolving behaviour over time.

As this is a strategic capability within the design team, the role also includes helping to define and mature Tangity’s human‑centred AI approach to product design. Alongside client delivery, you will contribute to establishing best practices, frameworks and reusable design patterns for working with AI, from discovery and experimentation through to production and governance. This includes helping shape our point of view for clients, contributing to go‑to‑market propositions, and supporting AI maturity assessments that help organisations understand where and how AI can create meaningful value.

In the early phase of the role, there will be a focus on building these foundations while supporting client engagements. Over time, you will become a key voice for AI‑informed design within the studio, helping teams design intelligent products that are not only technically powerful but also responsible, understandable and trusted by the people who use them.
