AI Lab Intern – Skin Tone Analytics & ML Pipelines

Teoxane; Genf; Hybrid; CHF 20,000 - 33,000; Full time

Job summary

Teoxane Laboratories, based in Geneva, Switzerland, invites applications for a 6-month internship in the IT department's AI Lab as part of Project ChromaDerm. The role focuses on building an image processing pipeline to measure skin color from clinical photographs and on developing a probabilistic model with uncertainty estimation.

We're seeking an ongoing Master’s student in Data Science or related field with strong Python skills (NumPy, pandas, scikit-learn) and image processing (OpenCV,

Qualifications

• Ongoing Master’s in Data Science, Applied Statistics, Engineering, or a related field.
• Strong Python: NumPy, pandas, scikit-learn, and image processing (OpenCV, Pillow).
• Solid applied statistics: variance components, uncertainty quantification, calibration.
• Familiarity with PyTorch; interest in colorimetry (CIELAB), LLMs and RAG is an asset.
• Curious, rigorous, autonomous; works well independently and in a cross-functional team.
• Fluent in English; French is an asset.

Responsibilities

• Build an image processing pipeline sampling skin color at multiple facial locations, with automated quality gating (facial segmentation, rejection of specular highlights, shadows and occlusions).
• Quantify measurement precision: variance decomposition across subject, site, imaging system, viewing angle and visit; repeatability and test–retest analysis.
• Characterize and correct or statistically account for differences between imaging systems.
• Develop a calibrated probabilistic model estimating Fitzpatrick skin type with explicit uncertainty, and a logic for flagging discordant cases for human review.
• Run pre-specified robustness and fairness checks across the measured skin tone range.
• Document methodology, results and code to ensure project continuity.
