The Team

The FUSE (Foundational User Experience) team's mission is to empower our product teams by providing a unified, efficient, and high-quality front-end ecosystem. We do this by owning and evolving the core UI/UX infrastructure, including our design system and component libraries, to create a framework enabling rapid development.

We're looking for a visionary Senior Front-End Ecosystem Engineer to join our growing team at Capital on Tap. This isn't your average front-end role; you'll be at the heart of empowering our entire engineering department, both internally and externally.

As a Senior Frontend Engineer, you'll play a pivotal role in shaping our development landscape. You'll architect, build, and maintain a best in class front-end ecosystem that enables our entire engineering department to efficiently build, test, and deploy front-end features in parallel. Your customers will include not only our external users but also your fellow Capital on Tap software engineers, as you empower them with the tools and infrastructure they need to excel. We're seeking someone who can think holistically about the unique challenges of building commercial front-end applications within a large, distributed global team, and you'll be keen to leverage modern tooling, including AI, wherever it can enhance our day-to-day development processes and outcomes. Finally, you'll mentor and share your expertise with our entire front-end community, nurturing a best-in-class culture of front-end engineering across the department.

We're seeking an engineer who is not just technically proficient but also a strategic thinker and a collaborative leader. If you're passionate about developer experience, enjoy tackling complex architectural challenges, and thrive in an environment where you can truly make an impact, we'd love to hear from you!

What You’ll Do

• Architect and maintain systems and processes to enable multiple product engineering teams to build, test, and deploy web solutions in parallel.
• Work with the Design Team to design and implement a component library of standardised and reusable UI components to provide a cohesive and consistent UI experience for our customers.
• Collaborate with product engineering teams to prototype and A/B test new components to enable new and complex product features.
• Define and document coding and architectural guidelines and standards, and disseminate those standards to the wider engineering team.
• Establish performance standards along with tools and techniques to enable the other Product Engineering teams to effectively monitor their systems as well as identify and rectify performance issues.
• Collaborate with the Security Team to foster a security first approach across Capital on Tap’s front-end community.

We’re Looking For

• 3+ years hands-on experience in React and Typescript, with a strong focus on modern web development.
• Proven experience with Next.js for building server-rendered and static React applications.
• Solid understanding and experience using React-Query for data fetching and state management.
• Experience building and maintaining design system components (tokens, UI libraries, accessibility standards) to ensure consistent, scalable and elegant frontend experiences.
• Good testing practices, in both Unit and Integration testing.
• Experience in using Agile development practices.
• A passion for learning new skills and technologies.
• A proactive, supportive, and collaborative team player.
