Senior Applied Scientist, Behavior AI & Anomaly Detection

Software Careers; Paris; Hybride; EUR 140 000 - 200 000; Plein temps

Résumé du poste

Datadog is seeking a Senior Applied Scientist for Behavior AI in Paris. You will design, train, and optimize models that process billions of logs in real time, focusing on high-throughput streaming and cost-efficient deployment.

You will build data pipelines, integrate models with production systems, and develop interpretability tools while maintaining operations across the platform. Strong math, ML, and software design skills are essential.

Qualifications

• Advanced degree in CS, engineering, ML, or applied math or equivalent experience.
• Hands-on experience training and fine-tuning models at scale in production.
• Strong math background and ability to reason about trade-offs between speed and accuracy.

Responsabilités

• Design and build mid-size models for high-throughput stream processing and train at scale.
• Optimize models across mathematics and systems for hardware efficiency.
• Build training data pipelines from raw streams to training-ready datasets.
• Collaborate with engineering to deploy models with attention to GPU utilization, latency and cost.
• Plan roadmap of model and system improvements tied to product needs.
• Develop an agentic layer to analyze, validate, and act on outputs.
• Create lightweight interpretability tools to explain model behavior.
• Maintain and monitor models, services and infrastructure; participate in on-call rotation.
