Junior Web Application Developer

We're a very serious software development company

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, we consistently focus on these principles: 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 such as DRY, SRP and YAGNI.

Looking to offer this service to a growing number of customers, we're looking for you to join our team on the projects we're working on now and in the future. All the while getting trained on the job to become a clean-coder and good developer overall.

Your role

As a junior web developer at TenTwentyFour1024, you will be working mostly full-time from our offices in Esch-sur-Alzette where you'll 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 implementing user-interfaces, back-end controllers and database structures alike; you will be involved in code quality assurance (peer review) and learn to produce clear, concise, functional and efficient code.

As a member of TenTwentyFour1024, you'll be sharing some responsibilities with the rest of the team, be a team-member on most projects and eventually a team-lead or even project-manager getting face to face with our customers on some projects.

TenTwentyFour1024 has made a habit of looking for team members dedicated to their work, even if they don't have a fancy diploma or 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

  • Implementation of intuitive user interfaces using the latest web technologies (Vue, Angular, …).
  • Development of server side back-ends and APIs (Node.js, Python 3, Ruby).
  • Development of hybrid mobile applications using Ionic, ReactNative and similar frameworks.
  • Continuous integration and deployment of our applications using Jenkins and Capistrano.
  • Design and execution of unit-, integration and acceptance tests.
  • Maintenance of and support for existing (sometimes legacy) applications.

Your strengths

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

  • …have already dipped your toe into current TypeScript/EcmaSript frameworks and libraries.
  • …are motivated and able to learn quickly and not afraid to act autonomously and take initiative.
  • …have a solid understanding of web technologies and protocols, as well as client/server architecture.
  • …know — or searched the Internet on — how Chai, Mocha and Jasmine do not exclusively refer to hot beverages.
  • …have good written and spoken skills in English. French, Luxembourgish and German are considered an asset but not mandatory.
  • …have a degree in a Computer-Science related field or not. We don't actually care, just show us that you're awesome at what you do!
