What you will be working on

As a (Senior) Full Stack Developer at Cosuno, you will work on the frontend as well as the backend side of our product and therefore will take full ownership over the features you are creating. After you develop a comprehensive understanding of the components of our product, you are given full responsibility to extend them and build on them in ways that makes our product more valuable, more reliable and better structured to ensure future maintainability.

Specifically, we have a frontend based on React and a backend written in Node.js. They interface with each other using GraphQL and Apollo. We utilize TypeScript for the entire codebase to improve code quality and reliability. We use relational databases as well as Elasticsearch. We write comprehensive end-to-end tests using Cypress in addition to unit tests. Our infrastructure is based on AWS and Kubernetes. We have a well-functioning CI/CD pipeline and deploy to production multiple times a day.
