About Safran

Safran is an international high-technology group operating in the fields of aeronautics (propulsion, equipment and interiors), space, and defense. Its mission is to sustainably contribute to a safer world, where air transport becomes ever more environmentally friendly, comfortable, and accessible. With operations across all continents, the Group employs 100,000 people, generating 27.3 billion euros in revenue in 2024, and holds leading global or European positions in its markets, either alone or in partnership. Safran ranks as the 2nd aerospace and defense company in TIME magazine's 'World's Best Companies 2024' list. Safran Electronics & Defense offers its clients embedded intelligence solutions that enable them to perceive their environment, reduce mental workload, and ensure trajectory, even in critical situations, across all environments: on land, at sea, in the sky, or in space. The company leverages the expertise of its 13,000 employees for these three functions: observe, decide, and guide, for both civil and military markets.

About the Role and Team

Ready to innovate within a major industrial group, contribute to a safer and more sustainable Space, and push the boundaries of space exploration? Eager to participate in large-scale projects alongside international players? Join the Safran Space Division and its 1350 expert and passionate collaborators! We develop, industrialize, and produce a wide range of technologies for connectivity, propulsion, navigation, timekeeping, optics, and space surveillance. In doing so, we contribute to strengthening our sovereignty, protecting Earth, and advancing scientific space exploration. Safran Reosc, a global leader in high-performance optics, designs innovative instruments for astronomy, space, science, and industry. Its optical components and sub-assemblies meet the most demanding specifications of research organizations and international scientific programs. Located 45 minutes from Paris and accessible by public transport, our Saint-Pierre-du-Perray site has 180 employees. It is situated in a green environment and features a company restaurant and a dedicated parking area for cars and motorcycles. It's a human-sized site where our activities in program management, engineering, industrialization, production, and all transversal functions (Commercial, Purchasing, HR, Finance…) that contribute to the entity's operation take place. As part of the production of Safran Reosc optics, the Optical/Mechanical Control Technician is integrated into the "Optical Surface Measurement" (MSO) department, which performs all optical and mechanical controls of optical parts during fabrication and acceptance. As a controller, your main responsibilities, after an initial on-the-job training phase, will be:

Key Responsibilities

• Independently perform mechanical control operations (3D Measuring Machines - MMT) to meet cost/quality/deadline/safety objectives.
• Execute operations by ensuring preparation (tooling, MMT program writing, etc.) and intermediate controls based on a manufacturing process.
• Ensure traceability of controls and record production-related information.
• Analyze control results using tools provided by the Measurement Line Managers.
• Detect anomalies, identify potential causes, and participate in root cause analysis.
• Contribute to continuous improvement projects.
• Perform first-level preventive maintenance operations.
• In a second phase, deploy your versatility by performing optical controls (interferometry, roughness measurement, etc.).
