apart from the crowd.

Your role

This position is open to juniors, mediors and seniors alike . We're not looking for a trainee with zero experience, nor are we looking for a one-track specialist. We're looking for a person that wants to grow and improve as a software artisan, regardless of their current level or skill-set. At TenTwentyFour , 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 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.

At TenTwentyFour , you will not be restricted to a single project, programming language or methodology. While we do develop and sell our own products, such as – customers like to work with us because we're not just a web-agency churning out websites from ready-made templates. Flexibility, versatility and adaptability are some of TenTwentyFour 's signature traits and we're very proud of the fact that our engineers do not simply execute blindly, but analyse, reflect and consult on the best path ahead.

Whether you're most experienced programming in TypeScript, Python, PHP or other programming languages, you'll be first assigned to the stack you're most comfortable with and subsequently be guided to gradually learn new techniques and widen your horizon to encompass the full variety of stacks that we work in.

TenTwentyFour has made a habit of looking for team members dedicated to their work, even if they don't have a fancy diploma in IT or countless years of experience. We believe that great talents have the ability to learn quickly and take advantage of new technologies, be it through formal or informal education. While experience can be acquired, persistence, the desire to learn and the self-confidence not to hesitate but to address problems and ask for help should be some of your strongest personality traits.

TenTwentyFour is not a full-remote company by design. But the times they are a-changing and we're no stranger to operating fully remote. While this position is open to fully-remote applicants , applicants who live close enough to drop by the office occasionally to not only share the work-load but also the community experience will be given preference.

Your responsibilities

As a web developer with TenTwentyFour , you will be responsible for…

• Development of server-side back-ends and APIs (, Python, PHP, Ruby, Rust, …) and integration with third-party APIs and libraries.
• Implementation of intuitive user interfaces using the latest web technologies (Vue, Angular, React, …).
• Development of hybrid mobile applications using ReactNative, Ionic or similar frameworks.
• Continuous integration and deployment of our applications using Jenkins and Capistrano.
• Research and application of clean architecture and good software design.
