Since 2013, JSL Energies Services has been supporting industrial players in France and worldwide.

Our mission: to strengthen your teams by bringing the flexibility and skills required for the success of your projects.

We provide passionate experts from a broad professional network, able to step in quickly to meet a one-off need, absorb a surge in activity or bring in new expertise. Agile and responsive, our lean structure fosters simple, human and long-term relationships with our clients, partners and consultants.

This proximity enables us to identify the right profiles – sometimes even the famous “five-legged sheep” – and to respond efficiently to the most specific challenges. Guided by respect for people, the environment and trust, we cultivate an open, caring team spirit.
