Criteo, a leader in the fiercely competitive Adtech sector, started in France and now has several hundred engineers distributed across four locations. Thanks to our strong engineering culture fostered by our founders, R&D driven innovation is at the heart of Criteo’s growth. Criteo’s engineering leaders went one step further and created a framework to continually evolve the culture to meet the needs of our growing team. We'll share our definition of engineering culture, describe its key elements, and elaborate on how it evolved over time.
