## Description

Senior Full-Stack Engineer | Node.js / AWS Serverless | Bristol | £60k + 15% bonus

Building the next generation of a major financial services platform's core client journeys - the kind of company most people in the UK have either used directly or know someone who has. This isn't a legacy-maintenance role: you'd be working across three repos spanning React frontends and full AWS serverless backends, with real ownership from investigation through to production.

What you'd be doing:

 * Building and maintaining features across high-traffic financial transfer journeys
 * Working full-stack: React frontends, AWS Lambda BFF layers, infrastructure as code
 * Owning issues end-to-end - not just writing code, but seeing it through
 * Flagging tech debt and driving CI/CD improvements rather than waiting to be asked
