About Us
We are the Information Intelligence Group (IIG) of CACI UK, a technical consultancy providing new bespoke solutions to solve our customers complex operational problems. Working as part of the Mood business at CACI IIG, we are looking for an experienced UX Design Engineer to join one of our product teams.
MooD is a large-scale data visualisation platform designed to bring disparate systems together into a single, coherent working model for management and future planning.
The Opportunity
This is a hands-on senior role covering UX research, web accessibility (WCAG 2.2), design systems, and cross-functional collaboration. Our platform is part of a suite of tools built on top of an established business architecture modelling engine, giving customers a way to visualise, structure, and interact with complex organisational and process data. The suite spans several connected products, from modelling and content authoring through to reporting and integration, allowing different types of users, from technical solution builders to everyday end users, to work with the same underlying data in ways suited to their role.
The core product you'd be working on to begin with is a responsive, web-based authoring tool that lets users build and structure content on a flexible canvas. It represents a significant modernisation of an older, desktop-only tool, moving the experience to something more visual, accessible, and intuitive while retaining the depth needed for enterprise use. Customers span sectors including defence and government adjacent industries, which brings additional considerations around accessibility, data handling, and security.
You will work closely with product owners, developers, and customers to shape the direction of the product and ensure it meets the needs of a range of user types across the platform. Typical responsibilities will include:
- Lead and facilitate usability testing sessions with internal stakeholders and external customers, including coordinating note-taking and ensuring findings are captured objectively ahead of analysis.
- Synthesise research findings into clear structured documentation that links insight directly to specific product areas and user questions.
- Translate research insight into well-structured tickets for the development backlog covering both defects and improvements.
- Champion accessibility as a built-in constraint rather than a retrofit, ensuring all features meet recognised accessibility standards.
- Contribute to and maintain design documentation.
- Work upstream of ticket refinement sessions to bring UX input into the process early rather than resolving issues within scheduled calls.
- Collaborate closely with development teams, including colleagues based in various locations and time zones, to bridge design and development.
- Provide day-to-day guidance and informal mentorship/support to a junior UI designer, supporting their development without formal line management responsibility.
- Support and contribute to working groups addressing handoff and quality assurance process gaps between design and development.
