Development Architect, responsible for the integration of the reactor and the industrialization of the design

  • Location : Aix-en-Provence technical platform
  • Contract : cdi
  • Start date : 01/12/2023

Mission :

Field: Engineering / Architecture

Attachment: Technical Department / Architecture and Integration Unit

Profile: Experienced Architectural Engineer; Disciplines General Engineering, Integration and Industrialization



Calogena was created within the Gorgé industrial group to develop, market, build and operate 30 MW thermal modular heat reactors to supply carbon-free heat to urban grids.

The Calogena reactor is a water-based SMR, with a very passive and simple design, which provides it with very robust safety. Calogena is the winner of the France2030 call for “innovative reactors” projects.

The preliminary design of the reactor is committed until 2025. This will be followed by a detailed three-year design and then the production of a prototype to prepare for the transition to the reactor series. Construction is expected to begin in 2030.

The APS team is in the process of gaining momentum. It is organized as a Project Platform, with an extended team capacity involving strategic partners. The Technical Platform is located in Aix-en-Provence.

The Project team consists of a project unit, an architecture unit, and a business unit. The cells are positioned on the Project Platform, placed under the responsibility of the Technical Department.

The architecture unit brings together the skills and capacities to carry out the development of the project in interaction with the managers of the project unit and the business unit
