What we are looking for: 5+ years of professional experience as a Data Scientist, with expert-level mastery of the Python data ecosystem (Pandas, NumPy, SciPy, Scikit-Learn).

Deep theoretical and practical knowledge of supervised and unsupervised learning, regression, classification, clustering, and time-series forecasting. Proven track record of moving models out of Jupyter Notebooks and into production environments using containerization (Docker) and microservice design.

Strong proficiency in writing complex, optimized SQL que
