Stories from our team members

“Kalray is a constant technological challenge. We work on innovative technologies, and it’s very motivating to think that we can play a role in tomorrow’s world. I’m in charge of security, and all the infrastructure for software development. My mission is to provide the teams with a quality framework for the development tools, and to allow them to work in optimal conditions. I like the diversity of the activities I can have, but also the fact that I can participate in this technological challenge with competent and motivated teams.”

“Kalray has developed cutting-edge technology that could change tomorrow’s world and the way data is processed. By joining Kalray, I wanted to give meaning to my work and be part of this unique technological adventure. I am the technical interface between customers and development teams. My missions are very varied and that’s what I like: acceptance and performance tests, debugging, but also customer support, POCs and demonstrations. I found at Kalray an agile and stimulating environment, with open-minded and supportive teams with a very high level of expertise.”
