Contract Type: Time & Materials
Duration: Initial 2 months (Extension highly likely)

We’re supporting a consultancy delivering a large-scale data and technology programme within a regulated, government-aligned environment.
As part of a recent service transition, they’ve identified a need for UI/UX expertise to support the handover, assessment and improvement of an existing front-end application developed by a third party.
The Opportunity
This is a flexible, part-time contract (circa 3–10 hours per week) ideal for someone looking to complement an existing engagement.
You’ll play a key role in:
* Reviewing and understanding an existing UI codebase
* Supporting technical handover sessions with incumbent developers
* Assessing code quality, structure, and scalability
* Providing recommendations to improve usability, accessibility and performance
* Helping shape the roadmap for ongoing UI development and support
Due to the nature of the engagement, there is a strong need for someone who can quickly get up to speed and provide immediate value.
There is also strong potential for this to evolve into a longer-term retainer or expanded scope as the programme matures.
Tech Environment
* React (modern, hooks-based)
* TypeScript
* Vite (SPA architecture)
* Context API (state management)
* Biome (linting)
* GitHub Actions (CI/CD)
What We’re Looking For
* Strong experience with React and TypeScript in production environments
* Experience working with modern front-end architectures (SPA)
* Ability to review and assess existing codebases and provide clear, actionable recommendations
* Comfortable working in ambiguous / discovery-led environments
* Strong communication skills with the ability to engage technical stakeholders
Strongly preferred:
* Experience working with GDS (Government Digital Service) standards
* (Important for hitting the ground running in a government-aligned environment with limited onboarding time)
Desirable:
* Experience with Vite or similar modern front-end build tooling
* Experience with design systems and accessibility standards (WCAG)
* Exposure to CI/CD pipelines (e.g. GitHub Actions)
* Experience inheriting or auditing third-party developed applications
Why This Role?
* Flexible, low-hour commitment alongside other work
* Opportunity to influence and shape a live production system
* Long-term potential within a multi-year programme
* Work with a modern front-end stack in a meaningful, regulated environment
