Career path


Because we know that the integration period is a key phase for each new employee and for us, we have set up integration programs adapted to each of our sites and businesses. This structured program is punctuated by formal and informal exchanges, individually or in groups, to help everyone find their feet, discover the Group, their site and their colleagues, and feel at ease in their new working environment.


From the moment they join the company and throughout their career, we support our employees in the development of their learning, skills and career paths. Whether it is through professional/certifying training courses or skills development support, our employees, HR experts and managers work together to define and implement the most appropriate solutions for each individual (technical training courses, specific training programs: management, project management, financial culture, etc.)

Life at Seqens


Quality of life

Quality of Life at work

For SEQENS, quality of life at work means improving the working environment and conditions, promoting social dialogue and strengthening the corporate culture.  

Numerous actions have been taken within the Group to improve the quality of life at work.  

Since 2017, and every 3 years, our employees participate in the “Great Place To Work” survey. The objective is to evaluate the quality of life at work and to capture “a snapshot of the employee experience”; the result is the Trust Index©, which focuses on assessing credibility, respect, pride and fairness within the company.

Our goals for the future  

  • 2024: Score 65/100
  • 2027: 70/100

The results of this survey have led to global and local action plans driven by our employees themselves: recurring communication actions towards all employees, celebrating successes, renovation of premises and network of kindergardens.

To go further, we have launched and made available to our employees the Sunshine-me platform, which aims to provide SEQENS employees with greater comfort through the provision of assistance and support services. The platform represents a new form of support for employees’ parenthood, family careers, psychological suffering and responds to the major challenges of all generations.
