Dublin, Dublin City, Ireland beBeeDataScientist Full time €120,000 - €160,000
Job Description:

As a seasoned professional in data science, you will play a crucial role in leading a group of skilled Data Scientists to manage fraud and loss metrics for assigned product lines or markets. Your expertise will be pivotal in developing and iterating on fraud-prevention frameworks that optimize transaction declines and minimize customer friction.

Key responsibilities include Portfolio Ownership, Strategy Development, Model Lifecycle Management, Stakeholder Alignment, and Performance Monitoring. You will be responsible for guiding the team in data preparation, feature engineering, model training, and validation using Python/R and cloud-native platforms such as BigQuery and Snowflake.

Additionally, you will host regular syncs with Business Units, Risk Operations, and Compliance to ensure models and business rules remain aligned with evolving policy and regulatory requirements.

Required Skills and Qualifications:
  • 8+ years of relevant experience working with large-scale, complex datasets, including at least 3 years managing a team of 3-6 Data Scientists in a fraud-risk or financial-services environment.
  • Proven ability to decompose ambiguous business requirements into a structured analytic plan and deliver data-driven recommendations.
  • Advanced proficiency in SQL and Python (or R) for data wrangling, EDA, and model development.
  • Expertise in exploratory data analysis and preparing clean, structured datasets for modeling.
  • Hands-on experience applying supervised and unsupervised learning techniques (regression, classification, clustering, decision trees, anomaly detection).
  • Familiarity with production ML frameworks (scikit-learn, TensorFlow, PyTorch) and cloud data platforms (BigQuery, Snowflake).
  • Deep understanding of fraud-risk principles, including AML/KYC, regulatory compliance, and performance metrics (Precision, Recall, ROC-AUC).
  • Strong track record of partnering with engineers, product managers, and business leaders.
  • Excellent verbal and written communication skills, able to distill complex findings into clear narratives for both technical and non-technical audiences.
  • A passion for inventing new approaches to big, ambiguous problems-always looking to build novel solutions that stay ahead of evolving threat vectors.
Benefits:
  • We offer a flexible work environment, employee stock options, health and life insurance, and more.
Others:

We provide equal employment opportunity to all persons regardless of age, color, national origin, citizenship status, physical or mental disability, race, religion, creed, gender, sex, pregnancy, sexual orientation, gender identity and/or expression, genetic information, marital status, status with regard to public assistance, veteran status, or any other characteristic protected by federal, state, or local law.
