About NTT DATA and Tangity
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.
What you'll be doing:
- Scope, plan, and lead service design activities across all phases of design and delivery
- Conduct mixed-method user research (interviews, contextual inquiries, usability testing, surveys, etc.) to uncover user needs and pain points
- Map and visualise services across layers (e.g. service blueprints, customer journeys, ecosystem maps, process diagrams) to reveal opportunities and drive alignment
- Synthesise research insights and identify patterns using frameworks such as Jobs to Be Done, service safaris, personas, and value proposition canvases
- Facilitate co-creation sessions, ideation workshops, and playback sessions with stakeholders and users
- Prototype service components and touchpoints (e.g. scripts, flows, mock service experiences) to test desirability and feasibility
- Translate insights into actionable service improvements, opportunity areas, and design recommendations
- Communicate complex service concepts and journeys through compelling storytelling and artefacts
- Embed accessibility and inclusive design principles throughout the service lifecycle
- Support junior designers with feedback, encouragement, and guidance
- Contribute to the ongoing development of Tangity’s service design practice, methods, and tools
What experience you'll bring:
Core Responsibilities
- Independently delivers high-quality design outputs with minimal supervision
- Participates actively in internal rituals (e.g. stand-ups, critiques, knowledge shares)
- Helps translate client or user needs into effective, actionable design solutions
- Begins to mentor or support junior team members with constructive feedback and encouragement
Expected Behaviours
- Takes initiative to complete work independently while knowing when to seek input or support
- Proactively communicates progress and asks thoughtful questions to deepen understanding
- Contributes to the quality and pace of the team’s delivery, offering ideas and solutions
- Demonstrates reliability, accountability, and a positive attitude toward challenges
What We're Looking For
- 5+ years of relevant experience in Service Design or a related discipline
- Strong portfolio demonstrating end-to-end service design capability across sectors or domains
- Confident in applying human-centred design principles and inclusive design practices
- Experienced in mapping services, synthesising insights, and facilitating collaborative workshops
- Proficient in communicating design concepts visually and verbally to stakeholders
- Familiar with agile environments and working in multidisciplinary product teams
- Knowledge of accessibility standards (e.g., WCAG) and inclusive design methods
- Strong written and verbal English communication skills
- Exposure to Government Digital Service (GDS) and service standards
