    Already after the first meeting, I knew that CKSource is a bull’s eye! The recruitment process was very smooth. I found a lot of interesting challenges here. I think CKSource is a great place for independent and creative people who value great communication with colleagues.

    I started my work at CKSource many years ago and from the very beginning, it’s been a place where people care for each other and each individual has a voice that matters. I still enjoy my time here, as new challenges come up and allow me to develop my technical and soft skills. And… I simply love our products!

    A newly hired employee can expect that their work at CKSource will not be completely isolated and that their voice will be heard and taken into account. They will receive feedback on both soft and hard skills - in an atmosphere of mutual trust and respect.

Life at CKSource


This is CKSource


More than 17 years ago, we started with a vision of developing rich text editing tools enabling anyone to write quality content for the web and we continue to do so today.


We design content management tools to meet the expectations of our users, not our own, offering quality when it comes to the code, user experience, our websites, and support.


Being an innovation leader in the web editing software makes us feel responsible for setting up the industry standards and staying ahead of future web content creation challenges.


We came a long way from an Open Source project to a mature tech company with a great team of more than 40 developers on board and constantly growing.


We create amazing Open Source tools that can be used by everybody thanks to a great amount of feedback, contributions, and appreciation from our community.


Our rich text editing solutions come with excellent documentation, technical support, and dedicated Sales and Customer Success teams.
