After two years of intensive training, the BTS (Higher National Diploma) often proves to be the ideal springboard for quickly entering the professional world. However, some students wonder whether they should continue in a technical field or focus on specializing in biotechnology or the environment. Between the race for innovation at giants like Genfit, Innate Pharma, or Novartis, and the growing demand for careers related to protecting the planet, the choice is not easy. The key lies in reflecting on one’s aspirations, skills, and desired career path. Today, many young people want to combine passion with concrete opportunities. Whether it’s to join companies like Sanofi, Biomerieux, or TotalEnergies, or to work in green tech startups like Algenol or water management companies like Veolia, the BTS diploma should be a step toward deeper expertise.
Why choose to specialize in biotechnology after completing your BTS?
Specializing in biotechnology after a BTS (Higher National Diploma) aims to deepen the scientific and technical skills crucial to meeting the sector’s challenges. Looking ahead to 2025, the biotechnology market continues to grow, particularly in medicine, the food industry, and the pharmaceutical industry. Companies such as Sanofi, Novartis, and Innate Pharma are constantly seeking professionals capable of manipulating DNA, cells, or bacteria to develop new drugs or vaccines. There is also strong demand for research into gene therapy or bioprocesses to produce innovative drugs. Specialization also allows you to differentiate yourself in an increasingly competitive job market. It is a dynamic sector that requires highly qualified technicians, particularly in companies such as Genfit and Biomerieux, which are pioneers in innovative solutions.
