Our teams

Motivated Men and Women
committed to Biosecurity

At THESEO, 115 employees, distributed over 4 subsidiaries, work together to develop our business and our products and are united around a common culture:

  • Safetyfirst and foremost for everyone, by implementing a far-reaching action campaign serving an ambitious Health and Safety policy: field safety visits, training sessions, challenges, compendium of good practices… At each site, THESEO is committed to drastically reducing the accident rate and more generally, to improving the quality of life at work.
  • Giving each person a sense of pride in their work, capitalising on the development of the talents and careers of THESEO’s employees. To this end, many training sessions are held each year among the employees to assist them in their missions. A social innovation for 2018, the Career and Development Conversation is also an excellent opportunity for each employee and his/her manager to plan within the organisation and facilitate internal mobility.
  • A spirit of teamwork and international cooperation, which allows us to act in synergy among our 4 subsidiaries. THESEO has evolved in a collaborative spirit in which our teams share the best of their experience, skills and know-how in an eager quest for solutions and adaptations to the market.
