You know the difference between shipping fast and shipping well.

Here, youll get to do both.

You will join a team that values clean, scalable engineering, good design, and the craft of building software that people enjoy using.

Our client is a Cardiff-based FinTech helping traditional financial institutions modernise how they run their private market operations making them more efficient, scalable, and competitive in the digital age.

Their platform is trusted by global clients and underpins private investment operations across multiple regions. Its already mature and secure, but they continue to innovate fast and expand internationally.

The Role

We are looking for a Senior Frontend Developer to help shape the next generation of their platform.

Youll work closely with product managers, designers, and backend engineers to build intuitive, performant interfaces that make complex financial workflows simple for users.

Youll have genuine input into how things are built, from design system evolution to performance optimisation in a team that values thoughtful, maintainable engineering over quick fixes.

Experience needed

Strong commercial experience with React and TypeScript
A focus on code quality, scalability, and maintainability
A good understanding of UI/UX fundamentals and accessibility
Comfortable working with AntD or other modern UI frameworks
Collaborative mindset- someone who enjoys sharing ideas and learning from others

You dont need to be a designer, but youll care about how your work looks and feels for the end user.

Whats on offer

Hybrid working: 3 days in Cardiff, 2 from home
£65,000 salary, depending on experience
A supportive, open-minded engineering culture that values quality and balance
Opportunities to influence architecture, tooling, and design decisions
A chance to make a real impact on a platform used by financial institutions worldwide

If you want to work somewhere that values craft, curiosity, and clean engineering, not just tickets and timelines, this is worth a chat.
