The Castelis Spirit

Our people are our strength

Joining Castelis, especially means becoming part of a community of people passionate about their work, supportive and committed. No matter what schools you have attended or the career path you have had! We are eager to hire people who are passionate about IT and who want to contribute their knowledge, skills and personality.

That’s why our managers and HR department will take the time to appreciate your talents through an HR interview and technical discussion. We attach great importance to sharing a reflection with you from the outset on your career prospects.

We work on niche technologies and want to guarantee you acquire as many qualifications as possible, so we also have an intensive certification policy. We also favour opportunities for dialogue so that everyone can share their knowledge and benefit from others’ feedback . That is why we regularly organise think tanks on IT best practices, but we also want to go further technically by constantly innovating: are you bubbling with new ideas? Every year, 5% of sales revenue is assigned to research and development.

It is also because we rely on the richness of your ideas that in 2017 we created the Caslab.

Our ambition, to grow together

You will have understood, joining Castelis is a unique opportunity to build the career you want.

In 2018, we have continued our commitment to quality of life at work to meet our employees’ expectations in terms of their work-life balance but also in terms of keeping employees with disabilities in work, by henceforth establishing a disconnection charter but also access to systems for nomadic and home working.

And if you are still not convinced that Castelis is a great place to work, we offer you a pleasant working environment and a range of relaxation spaces (table tennis, table football, PS4, fitted kitchen with unlimited drinks, 400m² terrace), as well as activities marking the life of the company throughout the year (corporate evenings, online gaming, sports competitions etc.) in order to contribute to everyone’s well-being.

Castelis, a great place to ...


We offer employees an ideal and friendly workspace. We provide a relaxation space with table tennis, table football and PS4.


Moments of sharing are precious at Castelis and several rituals have been added to the company’s life. "Monday and Wednesday is fruit”, “Thursday croissant”, etc.


Castelis encourages team cohesion by promoting the emergence of shared moments such as “Friday anything goes”, evening barbecues and in-house events.


The Works Council provides employees with preferential access to shows and leisure tickets, as well as the funding of their holidays and sports activities.
