You will be embedded within the engineering team of an FCA/PRA-authorised specialist bank in the UK, working across digital banking products that span Java/Spring Boot microservices, TypeScript/React frontends, and integrations with third-party financial systems. The specific platform and stream will be confirmed at the point of placement.
The team is small (~11–12 engineers), close-knit, and genuinely curious — actively experimenting with AI-assisted development. Many engineers have grown up inside this organisation, so someone with broader industry exposure will stand out, have real influence, and help shape the way the team evolves. You will own features end-to-end, contribute to cloud-native infrastructure on AWS, and work alongside product and QA in a flat, delivery-focused environment.
We are looking for someone with good communication skills, ideally with experience making decisions independently, being proactive, used to building and evolving production software, and with good attention to detail.
