A company culture that makes the difference
Joining Castelis means first and foremost becoming part of a community of passionate, supportive, and committed individuals. Regardless of your academic or professional background! We value people who are passionate about technology and want to contribute their knowledge, skills, and personality.
That is why our managers and HR team will take the time to discover your talents through an HR interview and a technical discussion. We place great importance on thinking through your career development prospects with you right from the start.
We work with niche technologies and aim to guarantee you maximum qualifications, which is why we also pursue an intensive certification policy. We also favour spaces for exchange so that everyone can share knowledge and benefit from each other’s experience. This is why we regularly hold reflection committees on IT best practices, and we also have the ambition to go further technically by constantly innovating — full of new ideas? We reinvest 5% of revenue into R&D every year.
It is also because we value the richness of your ideas that in 2017, we created the Caslab.
