Formerly Comex Nucléaire, we have over 30 years of experience in nuclear diving and operate in complex, hostile industrial environments with high safety stakes.
Our teams mainly work on nuclear sites (pumping stations, hydraulic structures, industrial circuits, reactor pools, fuel pools), but also across all industrial sectors.
As a Class 2 Diver with an A rating, you will join customized intervention teams of 4 to 5 people, depending on the nature of the work.
Your hyperbaric and underwater work includes:

- Bathymetry (siltation mapping)
- Additional work, study, and design of specific equipment
- Work at height (rope access technicians) depending on profile
The position is not limited to diving: you will also be involved in mechanical and industrial operations outside of diving.
