Senior Frontend Engineer

We are looking for an experienced Frontend Engineer to come and join our agile delivery team responsible for building some of the capabilities that enable us to provide brand-new experiences to our users, using the latest technologies. You will love working in a high-performance, entrepreneurial environment that values the craft of building cutting‑edge products and solving complex problems. You’ll be joining an established, cross‑functional squad, focused on building our design system, logged‑out website and other cutting‑edge technologies. We are always looking for ways to do things better and encourage new joiners to bring their ideas and ways of working to the table. Teach us some cool stuff, and we will teach you some, but most of all, you will have fun doing it. We are proud to say that our engineers at ClearScore are world‑class and at the heart of making this mission a reality for our millions of users.

Design, build, and maintain full‑stack solutions using Node.js and TypeScript, delivering data‑driven user interfaces and backend services. Build intuitive client UX utilising design systems and server‑driven UI frameworks. Optimise and scale databases for large‑scale applications, leveraging SQL, PostgreSQL, and indexing strategies to ensure performance and maintainability. Work closely with expert colleagues who will implement, monitor, and optimise real‑time data pipelines with Kafka, ensuring robust message handling and distributed system performance to power your features. Take ownership of end‑to‑end performance optimisation, both client‑ and server‑side. Lead the deployment and maintenance of production‑grade code and databases across multiple global markets. Monitor post‑release performance, leveraging tools for reliability and system health. Collaborate in an Agile environment, mentoring team members and those of other specialisms and fostering a culture of learning and continuous improvement. Contribute to the growth of our technology by driving improvements in standards, tools, and processes.

Skills we’d love you to have:

• Strong knowledge of React and SSR frameworks, such as React Router 7 Framework or Next.js
• Experience building services using Node.js and technologies like Fastify or Express.js
• Strong attention to UI consistency, accessibility, and visual detail
• Familiarity with design systems
• Familiarity with headless CMS platforms such as Contentful would be a plus
• You live for unit and functional testing, using tools such as Jest and React Testing Library
• Good knowledge of build tools such as Webpack or Vite
• Desire to mentor more junior members of the team and to pair program to share your knowledge across the team
• Strong collaboration skills and impulse to share your knowledge across the Frontend team and the wider tech community
• Ability to lead large projects with multiple engineers working on them
• Understand and drive build processes and CI tooling (e.g. Jenkins, Circle CI)
• You have opinions on what technologies and standards we should be using now and in the future - we always want to hear new ideas.
