Job Offer: Plone / Volto Developers (m/f/d) @kitconcept

Hi, we are looking for two new colleagues to join our team at kitconcept.

Who we are

  • Offices in Bonn (Germany) and Barcelona (Catalonia)
  • Work happens both at our offices and remotely (depending mostly on the personal preferences)
  • Day-to-day communication language is English

What we do

  • Building websites and intranets with Plone (Volto/Plone 6 almost exclusively these days) as well as custom web applications and mobile apps
  • Our clients are mostly from the public sector (universities, research institutions, government bodies, etc.) as well as from the corporate sector (media, industry, health, etc.)
  • Amongst others, we take care of the website and the intranet of one of the highest-profile German federal agencies as well as the internet and intranet of one of the largest research institutions in Europe (check out our case study from WPD 2021
  • Our clients are mostly based in Germany but we also work with clients from Europe, the US, and Japan.

Why you might want to work with us

  • Passionate: We are passionate about what we do and how we do it
  • Plone Core Contributors: We are heavily involved in the Plone community and long-term Plone contributors and core developers
  • Sharing Knowledge: We are constantly sharing our knowledge within the team and the Open Source communities and we are constantly learning and adopting new technologies at the same time
  • Community: If you aren’t already part of the Plone community, we will encourage and help you become part of it and feel at home (one of the first things that our new colleagues usually do is signing the Plone contributor agreement)
  • Innovative: We are the driving force behind lots of innovations in the Plone community, most recently: Volto and Plone 6
  • Open Source: We have a Open Source by default policy and share our work with the Open Source community as much as possible and encourage colleagues to do the same
  • Community Events: We regularly organize Open Source events, such as conferences ( ), sprints (e.g. the Beethoven Sprint series: kitconcept - Plone Beethoven Sprint 2019 | kitconcept GmbH Blog ), local meetups ( and barcamps (
  • Work-Life-Balance: We take care of our colleagues and our team. We try to avoid working over hours as much as possible and encourage and help you to ensure a healthy work-life balance. Nobody can be productive and produce the high-quality results that we expect when being overworked
  • Family-friendly: We are family-friendly (most of our senior staff has family and kids and we know it is important to be at home for dinner in time, we understand that when your kid is sick this is the most important thing in the world to take care of at that moment)

What we offer

  • A fixed, unlimited, full-time contract
  • Option to work part-time (e.g. 80%)
  • Modern hardware (Apple MacBook Air/Pro M1, large high-resolution screen, etc.)
  • Free conferences (Ploneconf, React Europe, etc.)
  • Being part of a kick-ass team of dedicated professionals and the opportunity to grow together with us!

  • Experience with Plone and Python
  • Experience with REST APIs (preferably Plone REST API)

  • Experience with testing, TDD, CI/CD would be a plus
  • Experience with large-scale migrations and transmogrifier
  • Experience with administrating and running *NIX-based server systems. Experience with container-based solutions would be a plus
