Service Designer Public Sector

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.

• *The Role**

As a Senior Service Designer at Tangity, you’ll operate as a core member of agile, cross-functional teams delivering human-centred, end-to-end service experiences.

You’ll take ownership of your deliverables, collaborate across disciplines, and contribute to a culture of learning and excellence.

You will lead service design activities with increasing autonomy—from framing challenges and planning research to developing holistic service models. You’ll help shape design outcomes that balance user needs, business goals, and technical feasibility. You’ll also begin to mentor junior team members, contribute to our internal service design practice, and support the development of our collective craft.
