To actively champion these values, we drive a dedicated program built to secure sustainable growth by supporting our teams across three core pillars:

Diversity: We are committed to attracting, developing, and retaining diverse talent across all our technical and corporate roles. With a strong commitment to empowering Women in STEM (Science, Technology, Engineering, and Mathematics), we offer dedicated mentoring programs for early-career female professionals, alongside Women in Leadership training for our middle management and technical leaders.

Inclusion: We foster a strong culture of belonging through multicultural awareness initiatives, inclusive workplace guidelines, and informal small-group meetings that connect employees directly with leadership.

Well-being: We treat mental health as a core safety priority for all employees. We support our teams with comprehensive resources, including an Employee Assistance Program, Manager Wellbeing Toolkits, and ongoing Quality of Life initiatives.

As part of our ongoing commitment to professional equality and transparency, and in accordance with French regulations, we publish the annual Gender Equality Index (Index de l'égalité professionnelle) for our three entities located in France:
