A selection of our books

As a web consulting and services company active in various diverse sectors, TenTwentyFour1024's projects range from Django-based web platforms and APIs built on Ruby-on-Rails to state-of-the-art MVVC single page applications running on JavaScript-centred stacks. (We love vue2, vuex, koa and almost everything that comes with ES6!)

Whether TenTwentyFour1024 is designing and implementing industrial apps for embedded systems or developing a mobile application to drive our client's sales, the same principles are always in the centre of our attention: Code quality through teamwork and peer-review, solid foundations through unit- and functional-testing and a powerful code-base through functional programming and proven engineering principles (YAGNI, DRY and KISS).

Your role

As a web developer at TenTwentyFour1024, working full-time from our offices in Esch-sur-Alzette, you will be facing multiple responsibilities and given challenging – yet rewarding – tasks at every stage of a project's life-cycle. Supported by your colleagues, you will be making architectural choices at the back- end front-end; you will be designing user-interfaces and database structures alike; you will be involved in code quality assurance and get face to face with our customers.

TenTwentyFour1024 has made a habit of looking for team members dedicated to their work, even if they don't have countless years of experience. We believe that great talents have the ability to quickly learn and take advantage of new technologies. While experience can be acquired, persistence and the desire to learn and succeed should be some of your strongest personality traits.

Your responsibilities

  • Design and development of intuitive user interfaces using the latest web technologies (Vue, Angular, …).
  • Conceptualisation and implementation of server side back-ends and APIs (Node.js, express and koa).
  • Development of hybrid mobile applications using Ionic, ReactNative and similar frameworks.
  • Design and execution of unit-, integration and acceptance tests.
  • Continuous deployment of our applications using Capistrano and Jenkins.

Your strengths

You're a good fit for this job, if you…

  • …are able to learn quickly and not afraid to take initiative.
  • …have a solid understanding of web technologies and protocols, as well as client/server architecture.
  • …have already dipped your toe into current JavaScript frameworks and libraries.
  • …have a knack for the DevOps approach and are not afraid to occasionally handle a Unix shell.
  • …know that Chai, Mocha and Jasmine do not exclusively refer to hot beverages.
  • …have great written and spoken skills in English and good ones in French. Luxembourgish and German are considered an asset but not mandatory.
  • …have a degree in a Computer-Science related field or not. Honestly, we don't actually care, just show us that you're awesome at what you do!
