Stagiaire Ingénieur Mécanique / Micromécanique — Audemars Piguet

Full description

To support our Continuous Improvement team attached to the Quality department, we are looking for our future Mechanical / Micromechanical Engineer Intern for a period of 6 months, starting from September 2026. Your main mission will be to study and model the oxidation mechanisms of carbon steels as a function of manufacturing parameters. This internship is part of a continuous improvement approach, with a direct impact on the robustness and performance of industrial processes. In this context, you will be responsible for:

• Responsibilities
• Studying the influence of different production processes (machining and turning, hardening and tempering, tribofinishing / trovalization and intermediate handling and storage steps) on the oxidation of carbon steel surfaces
• Defining and planning a design of experiments (DoE)
• Conducting tests in collaboration with production and laboratory teams
• Characterizing samples on microstructural and chemical levels (oxidation, roughness, metallography…)
• Statistically analyzing the results obtained (correlations, modeling, mechanistic hypotheses)
• Requirements
• You are in your final year of a mechanical engineering, micromechanical engineering or materials science program (EPFL or equivalent)
• You are proficient in statistical tools (DoE, variance analysis, simple modeling)
• You have good knowledge of metallurgy, particularly carbon steels
• You have a strong interest in industrial processes and material transformation mechanisms
• You demonstrate rigor, organization, and a structured analytical mindset
• You enjoy teamwork and have good interpersonal skills to interact with various stakeholders (production, quality, laboratory)
