Offer description

Your mission

As a certified hyperbaric works company (class A and class D), Onet Technologies is a major player in the field of hyperbaric works.

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:

 - Conventional mechanical maintenance

- Dismantling work

- Installation of inflatable barriers and cofferdams

- Cleaning in controlled and non-controlled areas (very high pressure + suction)

- Removal of foreign bodies

- Television examinations with photo and video recordings

- Underwater welding (patching)

- Work in confined and nuclear environments

- Inspections & appraisals

- NDT/NDT inspections: magnetic particle testing, immersion thickness measurements, ACFM, eddy currents, multibeam sonar expertise

- 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.

Your assets

You hold a valid Class 2 Hyperbaric Certification with an A rating and the professional title of public works diver, which is mandatory for this position. You have skills or an aptitude for welding, machining, and/or mechanics, and proven experience in a similar position.

 

Comfortable in industrial environments, you are able to work on technical installations such as pumping stations, pipelines, radiologically contaminated pools, or specific industrial equipment. You are willing to accept a versatile position in which your duties are not limited to diving.

 

You are rigorous, independent, and a good team player. You strictly enforce safety procedures and are able to work in constrained and regulated environments, particularly at nuclear sites.

 

This position is subject to an administrative investigation, in accordance with nuclear industry requirements.

Onet has been committed to diversity and disability for many years. Onet recruits and recognizes all talents.
