Senior Machine Learning Data Scientist in the Data Team at Catawiki, focusing on delivering scalable data products and production-ready machine learning models. You will collaborate with product and development teams to build robust models, explore extensive mobile and web data to tackle real-world business problems, and deploy scalable predictions using cloud infrastructure and Kubernetes. This role involves delivering end-to-end data solutions, identifying opportunities for ML improvements, and working with cross-disciplinary teams to implement new use cases. The ideal candidate has 5+ years of experience in data science, a strong quantitative background, fluent Python and SQL skills, and a track record of deploying ML models that serve real-time or batch predictions at scale. Familiarity with PyTorch/TensorFlow, Docker, Kubernetes, BigQuery, Spark, Airflow, Kafka, and CI/CD is a plus. The position is based in Lisbon, with a hybrid work model (two days per week in the office).
