Summary
👤
Senior🎓
Top SchoolChristophe Cossou is an ingénieur-chercheur with 13 years of experience combining scientific research and software engineering, currently working at CEA on space missions including CTA and ARIEL. Trained to PhD level in physical sciences, he specializes in Python (packaging, testing, scientific libraries), data processing and in-flight calibration workflows—most recently preparing commissioning for JWST’s MIRI instrument. Meticulous and highly organized, he designs end-to-end solutions: framing scientific questions, decomposing them into plans, building reusable libraries shared across teams, and documenting and testing for operational readiness. His background spans HPC system engineering, numerical simulation maintenance and application development, giving him a rare blend of hands-on coding and systems-level operational experience. Notably, he proactively identifies opportunities to mutualize tooling across projects to save time and reduce duplication.
