About the role

As a core member of our product development team, you’ll work hand-in-hand with UX designers, product managers, and fellow engineers to develop production-ready web applications, which include sophisticated data visualisation. As a skilled React developer with a proven record of delivering robust and secure front ends, you'll be part of a cross-functional, agile team, which is shaping the future of our flagship user interfaces.

What will you be responsible for?

Alongside our other frontend engineers, you will deliver web applications that are not only secure, scalable, fault-tolerant and performant but also intuitive and visually engaging.
By transforming complex datasets into compelling visual stories, your work will embody the cutting-edge nature of our solutions.
With a methodical approach to automated tests, both unit and end-to-end, you will ensure a foundation of reliability, setting a benchmark for code integrity within the team.
Embracing ownership, you will be involved from conceptual design through deployment and beyond. This requires both a strong commitment to continuous learning and a pragmatic mindset to know when to apply simple, robust solutions.
As a proactive voice on the team, you will contribute to raising our collective frontend standards through a pragmatic, principles driven approach to technology. You will collaborate with teammates, share knowledge, and help improve how we build and maintain our frontend systems. You will advocate for tools and frameworks based on their proven ability to solve our specific challenges, clearly articulating trade-offs rather than following industry trends.
By delivering consistently and frequently, as well as collaborating effectively with cross-functional partners, you will champion a product-minded approach that goes beyond task completion to ensure our product development is finely tuned to our customers' needs.

What skills, experience, and qualifications do you need to succeed in this role?

Essential

Experience with the React framework and proficiency in TypeScript.
Familiar with version control systems like GitHub.
Familiar with translating Figma based design prototypes, with openness to closer, more iterative collaboration with designers.
Familiar with CSS-in-JS libraries such as Styled Components.
An advocate and implementer of industry best practices in frontend engineering including automated testing, using frameworks such as Jest and React Testing Library.

What will help you thrive in the Frontend Team

Our product is technically demanding - built for domain experts who rely on it to do serious work. The frontend reflects that: a mature codebase, established patterns, and engineers who care about craft.

You will thrive here if you take ownership of your work end-to-end, find your own path to getting things done, and bring genuine curiosity to the problems in front of you. We value people who understand why conventions exist before proposing to change them - who build credibility through delivery, then use it to shape how we work.

We embrace AI tools as a natural part of modern engineering, and we are looking for someone who shares that outlook.

Our culture - What we can offer you

We offer a working environment that is inclusive, stimulates innovation and continuous learning, and that thrives on growth and change.

Our culture is underpinned by our values; they are what we stand for, part of our DNA. They help us to attract and retain the right talent and customers, help us make the right decisions and clarify how we should all behave and treat one another, they are:
