Your responsibilities

    • As a TYPO3 developer, you will work in a team, developing and optimising modern and complex Web projects. We look after some big-name customers, some of which are globally oriented. This results in demanding technical issues such as deployment processes, performance optimisation and the development of extensions for customer-specific requirements.
    • You are enthusiastic and have a keen quality ethos, which you actively continue to develop in your work environment. In co-creating our processes and standards, you have the opportunity to input your own expertise and be an important part of the big picture.
  • Realising TYPO3-based CMS projects
  • Independently solving problems in existing TYPO3 systems
  • Concept development and realisation of projects and TYPO3 extensions
  • Expansion of the development processes and involvement in the team’s professional and technical development
  • Close cooperation with all of the agency’s departments
  • Involvement in further developing our sunzinet standards


  • TYPO3 is your thing. Ideally, you know TYPO3 inside out and have already had the opportunity to put your expertise to the test within an agency. You are also interested in more than merely the basic technical aspects – you connect the dots and you understand the concept, ultimately bringing the project magically alive via the keyboard.
  • Smart clothes aren’t a must, unless clients are coming into the office. We want you to feel at home, but it’s also crucial that you apply yourself. The following would also be pretty great:
    • A good command of PHP, HTML, MySQL, CSS and jQuery
    • A good command of developing TYPO3 extensions
    • Practical experience in the implementation of complex TYPO3 systems
    • Practical development experience in TYPO3 and with TypoScript
    • Practical experience with Extbase and Fluid
    • Preferably experience with UML and TDD
    • Preferably experience with Git
    • Preferably experience with the Solr search system
    • Strong quality ethos in all development work
    • Agency experience preferable

If, on top of all that, you are a team player, are reliable and can work autonomously, we can offer you excellent job prospects.
