Frontend Engineer

As a Frontend Engineer, you will lead the development and implementation of high-quality, data-driven user interfaces that bring our complex systems to life. You’ll work closely with designers and backend engineers to ensure our web applications are performant, accessible, and maintainable.

This is a varied role where you’ll be designing reusable component libraries, ensuring adherence to accessibility standards, and optimising the user experience across devices and platforms. You’ll also contribute to the continuous improvement of our development processes and play a key role in shaping the frontend foundation of our growing product suite.

Key Responsibilities:

• Design and implement complex, data-driven applications using modern frontend technologies with a focus on performance and user experience.
• Work closely with UX designers to translate design mock-ups and wireframes into high-quality code.
• Collaborate with backend developers to integrate UI components with server-side logic and APIs.
• Build, maintain, and optimise reusable UI component libraries for consistent design and functionality.
• Ensure codebase quality, maintainability, and adherence to best practices, including coding standards and code reviews.
• Ensure consistent UI performance across different browsers, devices, and platforms through testing and debugging.
• Implement accessibility standards (WCAG) to ensure our applications are usable by all.
• Troubleshoot and resolve complex UI issues, applying a deep understanding of both technical and design aspects of the application.
• Continuously seek ways to improve the user experience through innovative design and functionality improvements.

Success in This Role Looks Like

You’ll consistently deliver high-quality, performant, and visually appealing user interfaces that enhance the user experience across our data-rich web applications. You’ll collaborate effectively with cross-functional teams, translating design requirements into functional code and ensuring seamless integration with backend systems. You’ll proactively identify and address UI performance and accessibility challenges, and contribute to building reusable component libraries that support a consistent design language across our products. Most importantly, you’ll exemplify a culture of continuous improvement, mentoring colleagues, sharing knowledge, and driving innovation that supports the success of the entire Data & AI team.
