About the Role
We are looking for a hands-on UI Developer to design, build, and support modern, AI-powered user experiences within a fast-paced, enterprise-scale data environment for a growing Investment Bank.
You will play a key role in shaping the frontend architecture of a new platform and data control plane, creating intuitive, responsive, and accessible interfaces that enable users to interact seamlessly with complex data and AI-driven workflows. This is a builder's role for someone who enjoys taking concepts from a blank page to polished, production-grade applications.
What You'll Do
- Design and build responsive, accessible, and high-performing user interfaces using React.js, Angular, TypeScript, and modern frontend frameworks.
- Develop reusable UI components, design patterns, and frontend architecture that can scale across multiple applications.
- Integrate frontend applications with backend APIs, AI services, and agent-based workflows.
- Build engaging user experiences for AI-powered applications, including conversational interfaces, data visualisations, dashboards, and workflow tools.
- Ensure applications meet accessibility, usability, and performance standards.
- Implement authentication, authorization, and role-based access controls within frontend applications.
- Write unit, integration, and regression tests to ensure reliability and maintainability.
- Support and maintain production applications, troubleshooting issues and continuously improving the user experience.
