Senior fullstack frontend engineer

Senior Fullstack Frontend Engineer

We’re looking for a talented Senior Fullstack Frontend Engineer to join a close-knit, cross-functional agile squad within our Universal Mission.
Universal powers the ClearScore Group ecosystem internally, externally and across markets. Our purpose is to make ClearScore Group, its tools, APIs and identity systems universally accessible, consistent and self-serve, for internal teams and external partners.

What you’ll work on

Depending on where you land, you’ll contribute to one (or more) of these areas:
Accounts (Identity Surfaces)
Owns the user-facing identity experiences across ClearScore and connected brands: registration, login/authentication, My Account, bank connections, and document handling.
Toolsmiths (Internal Tools & Admin Surfaces)
Builds and runs internal tools and admin surfaces that enable Customer Ops, Partners and internal teams to self-serve.
Connect (Universal API & Developer Experience)
Owns and evolves the Universal API, API management tooling, external partner connectivity, and developer documentation/portals to support integration and interoperability across the platform.

Why this role matters

Your work will unlock safer, smoother access to ClearScore experiences across markets and brands, and it will reduce friction for the teams and partners building on top of our platform. That might mean improving conversion through the user registration flow, rebuilding core account management surfaces, enabling internal operational tooling, or shipping a developer-facing documentation experience that scales.

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

Why ClearScore?

ClearScore is currently the biggest marketplace for credit products in the UK and in South Africa with over 15 million users. We are the first company to facilitate access to credit products using Open Banking data, making credit accessible to users with no credit files or low credit scores. In the UK alone, we have established relationships with over 50 of the main lenders and have been a trusted tool for customers to manage their credit and make better financial decisions.

We were the first business to offer free credit reports. We did so because we are user-centric at our core and believe in leveraging on technology to enable positive financial choices. We are design-led and data driven and we embed these behaviours in everything we do.
