Data Scientist/Data Engineer

emagine Polska is seeking an AI/Data Engineer for an international project focused on building AI-driven data solutions for web content processing, attribute extraction, and market expansion. The role involves designing data pipelines, fine-tuning ML models, and working with Python, Spark, and NLP. The project is hybrid in Warsaw with a 3-month contract.

• Building and optimising Spark pipelines for large-scale web content ingestion and processing.
• Using Python, including Polars and/or Pandas, for data processing, analysis and pipeline development.
• Fine-tuning lightweight ML models for task-specific attribute extraction.
• Preparing training data, managing data quality and evaluating model performance end-to-end.
• Working with NLP techniques to extract, classify and reason over information from web content.
• Expanding an internal AI research agent to new geographic markets and adapting logic to local data conditions.
• Supporting evidence collection and reasoning logic for new place-related attributes.
• Evaluating ML systems across different locales, domains and data sources.
• Working with pipeline orchestration, optimisation and multi-source ingestion processes.
• Potentially using Scala and Spark in data engineering tracks.

• Strong Python skills, especially with Polars and/or Pandas.
• Experience with NLP and fine-tuning lightweight ML models.
• Practical experience in designing, building and evaluating data pipelines.
• Experience with Spark and, ideally, Scala.
• Familiarity with agent frameworks, especially LangGraph.
• Understanding of data quality, model evaluation and performance measurement.
• Ability to adapt ML/data solutions to different countries, languages and data domains.
• Experience with pipeline orchestration and optimisation for large-scale data ingestion.
• A hands-on, problem-solving mindset and ability to work in a fast-moving environment.
