• Oversee and continuously improve automated data QA, anomaly detection, and pipeline health monitoring.
• Mentor and collaborate with a team of data engineers and parsing specialists; review code, set best practices, and drive technical strategy.
• Research and integrate new OSINT sources, LLM tools, and enrichment pipelines for deeper coverage and higher data reliability.
• Prototype and productionize innovative data enrichment features using LLMs, graph analytics, and custom ML models.

• Partner with product and engineering teams to translate business needs into scalable, production-ready solutions.

   

What You Bring

• 5+ years experience as a data scientist or ML engineer, ideally with experience in OSINT, unstructured data, or large-scale data platforms.
• Deep expertise in Python, NLP (spaCy, HuggingFace, NLTK, etc.), and entity resolution at scale.
• Strong background in building and scaling data/ML infrastructure (airflow, Prefect, or similar).
• Advanced SQL skills; experience with large datasets (Postgres, BigQuery, Snowflake, etc.).
• Demonstrated leadership: have built, mentored, or led small teams or technical projects.

• Bonus: Experience in alternative investments, financial data, or OSINT.

• Preferred location: Ukraine or Eastern Europe.
