As a web consulting and services company active in various sectors – such as healthcare, logistics, restauration, education, funds-industry or payroll management – TenTwentyFour¹⁰²⁴'s versatility and professionalism have earned us a variety of projects that employ a multitude of technology stacks and programming languages.

Strongly focussing on JavaScript-centred stacks – we love vue2, vuex, koa and almost everything that comes with ES6! – we're now looking for a medior to senior on-site developer to further drive code-quality, productivity and innovation.

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 (YAGNI, DRY and KISS).

Your role

As a medior or senior web developer at TenTwentyFour¹⁰²⁴, working full-time from our offices in Esch-sur-Alzette, you will be making architectural choices, as well as determine and update the technology stacks of new and existing projects. Based on your prior experience in JavaScript development, you'll be the goto-person when it comes to tackling those parts of our applications that need to be performing fast and secure. As such, you will be leading a team of junior/medior web developers on some of our main projects and watch over their code quality via peer-review.

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

TenTwentyFour¹⁰²⁴ has made a habit of looking for team members dedicated to their work, even if they don't have countless years of experience. While we obviously require some experience for a medior to senior position, we still 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

• Application architecture for both front- and back-ends.
• Design and execution of unit-, integration and acceptance tests.
• Domain analysis, algorithm research, design and implementation.
• Code-review, guidance and role-model for a team of junior and medior developers.
• Development of intuitive user interfaces in ES6+ (Vue, Angular, React, …).
• Conceptualisation and implementation of server side back-ends and APIs (Node.js, express and koa2).
• Development of hybrid mobile applications using Ionic, ReactNative and similar frameworks.
• Continuous deployment of our applications using e.g. Capistrano and Jenkins.

Your strengths

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

• …are able to lead a team of web-developers in taking technical decisions.
• …have a solid understanding of web technologies and protocols, as well as client/server architecture.
• …have some notable experience in current JavaScript frameworks and libraries (e.g. ramda, lodash, lonad).
• …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. A decent working-level in French is definitely an asset. Luxembourgish and German are considered a nice to have and 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!
