Since day one, the personal development of our employees has been closely linked to the corporate development: we believe that the success of the company relies on the success of its employees.

Our HR strategy aims to build successful teams and create the conditions for individual and collective commitment in a sustainable way.

We are committed to creating the best office environment (up to the ping pong and foosball table, and you can even ride and park your bike at the office). We utilize the best IT tools for efficiency when working remotely while maintaining full security of the confidential information exchanged with the servers.

To achieve this goal, we encourage initiative and autonomy, allowing everyone to act and express themselves in their work and establish core principles of respect, responsibility, and trust at the heart of our relationships.

We seek to recognize the contribution of our employees by offering them the opportunity to grow within the company and express their potential. Any achievement is a relevant justification for a team lunch, which is another important corporate value.

  • Coming fresh out of my master 2 at Paris Saclay in Toxicology, joining Socosur was an unexpected surprise. I first learned about the company from another fellow student in my master. From the first interview with CEO Matthieu Chareyre, you could tell you were in for a enriching first experience.

    I started my internship at Socosur in the end of January 2020 as part of my M2 program in toxicology and risk assessment. Ever since i joined the team, I gained an immense experience from every person working there and was allowed to put my skills to good use.

    In the span of 6 months, I was able to prepare and develop toxicological reports, mostly permitted daily exposure reports. I was able to put my toxicological knowledge into practice. I was part of the team that elaborated digital marketing content for the toxicological section of the website.

    I now proudly occupy the position of Occupational and Cosmetics Toxicologist.

    With every new challenge we face on a daily basis, we learn the importance of team work. We thoroughly assess every decision and every choice we make all in one goal, the success of the company.

    Here at Socosur, you will meet dynamic people, full of passion for their work. The environment created provides the motivation to grow professionally and to develop even further your capabilities.

    This world of opportunities is open and it is yours to grab.
