Referment

Referment is working with a well-known UK financial comparison brand whose free online service lets consumers compare products from credit cards to savings accounts, loans to travel money, part of a larger group of comparison and mortgage brands. The Financial Services team builds the web apps, back office systems and tooling that power financial product comparison, integrate partner APIs, track sales, optimise marketing and drive reporting, and is growing its offering to small and medium businesses. The stack is TypeScript, React and Node.js (Bun where it fits), running on Kubernetes in AWS.

The Role

As Staff Software Engineer, you will set the technical direction for Financial Services and raise the standard the team holds itself to. Most of your day lands on the front end, but you own quality end to end: infrastructure, databases, pipelines, servers, CDNs, responsive accessible React components aligned to the design system, real-time metrics and alerting. You will turn commercial and customer problems into working software, put a value on the problems worth solving first, and make the engineers around you better, measured by what the team ships rather than what you ship alone. You will run code reviews, give and take direct feedback without ego, and keep applications tested, secure and maintainable. AI fluency is a core requirement: the team already runs AI inside live workflows, and you will find concrete uses for AI that move a metric, then help other teams adopt what actually works.
