MERN Stack Developer

Our front-end applications are written in React with TypeScript using Gatsby and Next.js. For our REST and GraphQL APIs we use TypeScript and NodeJS, with PostgreSQL and ElasticSearch behind the scenes.

All of our services are hosted on AWS using Elastic Kubernetes Service. CI/CD is handled by Jenkins, with automated Docker builds and deployments to staging. We use Github and JIRA to help us keep on top of our tasks, manage and host our code.

We have a strong culture for testing. We are individually responsible for our work and are immensely proud of the quality we produce. We try and automate as much of the testing as possible.

We have a learning and development budget for keeping up to date which can be spent on conferences, courses, and even books. We encourage sharing what we learn with the rest of the team and the wider community.

We are truly cross-functional: as well as designers and product managers, our teams include data analysts, mortgage advisers and marketing specialists. We’re focused on results: meetings are banned two days a week, and if you need to work from home to finish a project or leave early to manage your energy we encourage you to take it.
