Role Overview

We’re seeking a dynamic, forward-thinking  Service Designer with excellent communication skills. You will be open-minded, happy to work on your own or as part of a team and want to learn new technologies and promote best practice. 

As a Service Designer you will help us design coherent, integrated service offerings based on user needs, and define the design strategy for a service or set of services. You’ll work in a multidisciplinary team alongside researchers, designers and developers, to deliver word-class, user-centred services. You will bring extensive experience designing public, commercial or third-sector services. As a passionate advocate for designing integrated experiences, you will be persuasive and collaborative with a wide range of stakeholders. You’ll be part of our active and supportive design community.

What You'll Do

  • Understand user needs and create user journeys that help people successfully navigate complex systems 

  • Identify where separate interactions should act as one service and design rational user journeys within that service, as well as commonalities in activities across services that create opportunities for product development 

  • Analyse failure within existing services, identify root causes for that failure, and create designs or recommendations to address that failure 

  • Develop future service propositions that deliver on policy intentions 

  • Help to plan user research and usability testing, observe sessions, and help to analyse the results of user research 

  • Identify opportunities for cost reduction and improvement within an existing service 

  • Understand the existing support system for a service (both digital and process based) and design targeted improvements to existing services or to accommodate new services 

  • Map current service journeys and create blueprints for improved and/or new services 

  • Create and rapidly iterate service prototypes 

  • Identify and design service patterns 

  • Identify the right ways to measure service success 

  • Build collaborative relationships with stakeholders, across teams and service domains 

  • Define and conduct excellent stakeholder engagement 

  • Be a knowledge expert in service design 

  • Participate in thought leadership; introduce ideas and approaches to the broader team 

What You'll Bring

Essential Skills & Experience

  • Ability to design complexity out of services 

  • Significant experience designing digital products and/or services and planning service design project engagements 

  • Significant experience planning and running workshops with stakeholders, end users and/or front-line service providers 

  • Solid understanding of user research methods and practice, proven experience in using metrics and user feedback to define/refine services and be able to work collaboratively with user researchers and interpret research findings 

  • Ability to analyse and visualise user journeys and service flows 

  • Ability to clearly and persuasively communicate designs as well as the evidence underpinning decisions 

  • Work collaboratively with multidisciplinary teams 

  • Ability to work quickly in an agile environment 

  • Have a design related degree, or relevant industry experience 

  • Exceptional skills in convincing people of the benefits of user-centred design and designing integrated service offerings 

  • Basic understanding of html and css 

  • Experience of introducing positive change into working practices, teams or organisations 

  • Leadership and excellent communication skills; clear ability to collaborate and build useful relationships

What Makes You a Great Fit

We're looking for someone who is naturally curious and empathetic, with a genuine passion for understanding people and their needs. You thrive in collaborative environments and enjoy translating research insights into actionable recommendations that drive meaningful improvements to services.

You're comfortable navigating ambiguity and can balance methodological rigour with pragmatism when needed. You enjoy advocating for users while understanding business constraints, and you're able to communicate complex ideas in simple, compelling ways that resonate with different audiences.

Your attention to detail is balanced with an ability to see the bigger picture, and you're constantly looking for ways to improve how we work. Most importantly, you're passionate about creating inclusive, accessible services that work for everyone, regardless of their background or abilities.
