AI Scientist - DeepTech (M/F/X)

💰 80–120 K€ gross / year 📍 Paris area (on-site several days / week) ⏳ Start: ASAP

🏠 Remote: 2 days / week after probation

🌍 Language: English fluent / French optional

🎓 You must have a Ph

D in Machine Learning to apply. Join a deeptech startup building Foundation Models for structured data (tabular & time-series) instead of yet another generic LLM.

As an AI Scientist, you will work on pre-training, fine-tuning and synthetic data modelling of large transformer-based models, at the core of a production-grade platform used by major enterprise and digital-native clients. You report directly to the scientific leadership and collaborate closely with a compact team of ML engineers and researchers.

🎯 What You Will Do

Design and improve foundation models for structured data (tables, time-series) based on modern transformer architectures

Pre-train, fine-tune and evaluate large-scale deep learning models in the cloud or on private clusters

Build and maintain evaluation frameworks and metrics aligned with real customer use cases (classification, regression, forecasting, anomaly detection)

Drive active learning strategies and training data optimisation: sample selection, dataset curation, synthetic data generation, robustness and transfer learning

Stay on top of the latest ML research and propose model or training improvements that translate into measurable performance gains.

Communicate research ideas to the scientific community and experimental design to the internal ML team (papers, talks, internal notes)

Collaborate with ML engineers, data scientists and customers to deliver representation algorithms that unlock high-impact downstream applications.

Run ad-hoc analyses to understand and debug model behaviour, failure modes and scaling p
