SambaAmsterdamHybridFull-time3 weeks ago

Samba is hiring a Senior Data Scientist to shape its data science function for the agentic era of advertising. The role involves owning end-to-end delivery of data science projects, building production ML systems, and applying modern AI and agentic capabilities across data products. Requires 8+ years of hands-on data science experience and advanced Python, PySpark, and MLOps skills.

What you'll do

Own end-to-end delivery of data science projects, from problem scoping through production deployment, building production-quality Python and PySpark on Databricks that is well-tested, documented, and reusable.
Define and ship the modeling methodology behind Samba's data products, including model selection, evaluation frameworks, and reproducibility standards, applying core ML and statistics to billion-row, real-world data.
Partner with Data Engineering to define data requirements, validate pipelines, and ensure model inputs are reliable and production-ready.
Build and operate advanced AI systems using retrieval-augmented generation (RAG), large language model (LLM) augmented modeling, and Graph Neural Networks that improve as signals evolve and support agentic decision-making.
Integrate LLMs and agentic workflows into production ML pipelines where they extend modeling capability and unlock new product surfaces.
Drive technical design for modeling components, translate business requirements into modeling solutions with product, engineering, and go-to-market partners, and mentor data scientists through feedback, pairing, and design review.
Establish and operate MLOps practices (experiment tracking, Airflow orchestration, model monitoring, retraining workflows) and apply privacy-compliant data handling, including GDPR, CCPA, and Samba's data governance policies.
