Senior Fullstack Frontend Engineer

About the Role

We are looking for a talented Senior FrontEnd Engineer to join our cross‑functional agile delivery team working on the Credit Health and Home Surfaces of the Clearscore product.

Your work will empower consumers worldwide, across all five markets in which Clearscore currently operates, and will focus on helping users to understand their credit position – how lenders see them & their borrowing potential.

We do this by presenting data from their Credit Bureau reports and Open Banking connections in easy‑to‑understand experiences, empowering and educating them to take effective control of their finances.

You will build these experiences using components from Slate, our design system, put together as pages using a Server‑Driven UI system. You will implement business logic server‑side, building pages once in our Node.js service and seeing them delivered across the website and Android and iOS native apps. This architecture is underpinned by an event‑driven Kafka backend delivering the data you need to materialise to power the new experience you are delivering.

This team is part of the Surfaces mission at Clearscore, working alongside teams delivering other parts of the same product such as Protect and the Financial Products Marketplace. As a Frontend Engineer, you’ll thrive in full‑stack environments, leveraging your expertise across every layer of the stack. You’ll build and optimise databases for massive datasets, develop robust backend services in Node, and create engaging client interfaces using a design system and server‑driven architecture. Your deep understanding of monitoring, analytics, and troubleshooting will ensure high‑quality technical delivery backed by measurable performance.

In this role, you’ll play a key part in your team, helping juniors grow and peers deepen their technical expertise. You'll bring fresh ideas and perspectives to our engineering culture, helping us refine how we deliver world‑class products. We value collaboration, attention to detail and continuous improvement. If you love solving complex problems and delivering elegant solutions in a fast‑paced environment, we’d love to hear from you.
