Ui Ux Designer jobs in United Kingdom

Allica is the UK’s fastest growing company - and the fastest-growing financial technology (Fintech) firm ever. Our purpose is to help established SMEs, one of the last major underserved opportunities in Fintech.

Established SMEs are the backbone of local communities - representing over a third of our economy - yet have been largely neglected both by traditional high street banks and modern fintech providers.

Technology sits at the centre of Allica. We design and build the platforms that power the bank, working closely with every part of the business to deliver real impact for customers. Our teams move quickly, focus on outcomes, and take ownership from concept through to delivery. We solve complex problems, modernise processes, and enable the business to scale with confidence.

What makes us different is the level of influence and autonomy engineers have. We work without the weight of legacy systems, which means we can focus on building for the future. Everyone contributes ideas and helps shape how we operate, and roles evolve as the organisation grows. This is a place for people who want to have a tangible impact and do their best work in a modern, collaborative environment.

• You will use your expertise in web technologies and backend systems to shape how payments flow through our digital products. You will define and roll out technical patterns that are used across multiple squads, including authentication, design system tokens and tracing. You will reduce complexity, improve delivery consistency and support teams in building scalable systems.

• Encourage broad participation in communities of practice to share knowledge and improve standards across the organisation.

• Expert knowledge of JavaScript, TypeScript, React with Hooks, Redux, HTML5 and SASS/CSS.

• Strong experience with unit, integration and end-to-end testing using tools such as Jest, React Testing Library, Playwright or Cypress.

• Experience designing and delivering backend services in Kotlin or Java using REST and OpenAPI.

• Experience in system design at scale and the ability to simplify architectures across multiple teams.
