    Project description:

    You will be part of the EMFE department. Working on the group level, EveryMatrix Front-End (short EMFE) is the department that manages everything related to the front-end: from some banners or the need for a logo to a fully functional, cutting-edge online casino. We are composed of 5 teams: Bespoke Team, Business Team, QA Team, Native Apps team, and Widgets team. This position is open inside the Bespoke Team.

    We use a wide array of technologies, and we love to stay on the bleeding edge.

    You will be working mainly with React, Redux, WebPack, and NodeJS, using HTTP2 and WebSockets APIs as the transfer protocols between the server and the client. We deploy containerized apps via Docker, Kubernetes, and a continuous delivery pipeline.

    It’s an exciting product (especially for us and hopefully for you) and we’re looking for people who are ready to face a challenge, analyze existing functionality and transform and adapt it into something great using the latest stack of Web technologies.


    You will be working on our own framework that is built on top of ReactJs. This is a cool new project that we’ll be using to deliver white-label websites faster than ever. You will be part of the core team of the framework working on the most interesting and challenging things. Amongst the most important responsibilities of the role, you will have are:

    Code quality – You understand the standards that are enforced by the coding guide and keep compliant with them. You are a promoter of clean code and help more junior colleagues do the same through code reviews and feedback.
    Code review – You are actively involved in code reviews. You make sure that all coding standards are followed and that the submitter understands completely not only what to modify but why to do the changes that are required.
    Refactoring – You easily understand the existing code in the project and can identify the need for refactoring.
    Scalability, stability and performance – You implement improvements and can offer solutions / alternatives on how to develop the code to further improve scalability of the project.
    Code documentation – You document your work and how it affects the entire project (when applicable). You add comments in code according to standards / readme. You always keep your documentation up to date.
    Operational – You can handle simple incidents according to the defined SLAs and project processes (the complexity refers to system/platform complexity, technical solution complexity or business knowledge).
    Communication – You contribute to best practices knowledge sharing and application within the project. You know how to share knowledge in many forms: feedback, presentations, recommendation of books and articles, recommendation of events, lessons learned etc.
