Software Engineer

We’re currently working to bring dark mode and font size customization to our users, as well as enhancements to the accessibility of our pages. We are exploring a future focused on growing our platform capabilities, and working with our communities to improve the flexibility and consistency of the user experience across the desktop and mobile web. As a full stack engineer – with both backend and frontend experience – you will be responsible for making changes to both our javascript-based frontend and our PHP-based backend code. For this role, the majority of your time will be spent on the frontend user experience and our skins-based templating system, but you will also be asked to make changes to backend services, metrics, and other non-user-facing code. You should be comfortable with benchmarking, running synthetic tests and have an understanding of XSS and how to prevent them, as well as productioning backend services.
