Image Processing Intern: AI-Assisted Tools for CalVal

The role

The intern will support the End-to-End Validation & Performance team on image processing and calibration/validation work for Earth-observation missions. The work includes building a reproducible dataset, a baseline estimator and an evaluation of correction quality, then presenting findings to stakeholders.

What you will do

• Review DSNU, radiometric calibration and EVP processing and CAL/VAL practices
• Identify suitable routine images, metadata and reference calibration data with EVP engineers; document limitations and provenance
• Prepare a reproducible dataset and reference baselines with a holdout evaluation strategy
• Implement a baseline estimator combining a data-fit term with a regularizing prior
• Investigate additional AI/ML methods where suitable data exist and compare them against the baseline
• Evaluate correction quality, residual fixed-pattern structure, stability, runtime and failure cases
• Package the workflow as a prototype script or notebook with plots, quality checks and an auditable record
• Present findings and recommendations to EVP and CAL/VAL stakeholders

Required qualifications

• Student in engineering, applied physics, remote sensing, image processing, data science or a related field
• Fundamentals of signal or image processing
• Strong interest in Earth observation
• Basic programming skills in Python and comfort working with scientific data
• Analytical mindset, rigor, and ability to document assumptions and limitations
• Interest in calibration, validation, sensor behavior or image quality assessment

Nice to have

• Exposure to satellite imagery or remote-sensing data
• Experience with optimization, statistical estimation or machine-learning evaluation
• Familiarity with image-analysis libraries and scientific Python tools
• Understanding of radiometric calibration or data-quality assessment

Benefits

• Lunch vouchers (tickets restaurant)
• Sustainable mobility package (forfait mobilite durable)
• International environment with 20+ nationalities
• Mentoring program throughout the internship

Before you apply

• Attach a copy of your resume in English
