About the Role

The Senior Data Scientist is a key member of the Data Science department, responsible for developing advanced models, driving innovation in predictive analytics, and delivering insights that shape business strategy.

This role requires a strong mix of technical expertise, business acumen, and leadership to design and implement high-impact data science solutions in areas such as credit risk, customer analytics, fraud detection, and portfolio optimization.

The Senior Data Scientist will mentor junior team members, collaborate with cross-functional teams (Data Engineering, Credit Risk, AI & Platform Engineering, and Research & Analytics), and ensure that data science initiatives are production-ready, scalable, and aligned with business objectives.

What You’ll Do

Design, build, and validate predictive models (classification, regression, clustering, etc.) to support credit risk, customer analytics, and decisioning.

Partner with Data Engineering to design and refine feature-engineered datasets for scalable model development.

Work with AI & Platform Engineering to deploy, monitor, and maintain models in production environments.

Lead deep-dive analyses to identify trends, improve decisioning strategies, and unlock business opportunities.

Collaborate with the Credit Risk team to ensure models meet regulatory, compliance, and governance standards.

Guide junior data scientists and analysts, fostering best practices in model development, testing, and documentation.

Explore new machine learning methods, AI frameworks, and analytical techniques to enhance departmental capabilities.

Translate complex data-driven insights into clear, actionable recommendations for senior leadership and business stakeholders.

What You’ll Bring

Master’s or PHD in Data Science, Statistics, Mathematics, Computer Science, or related field.

5+ years of experience in data science, with a proven track record of delivering models into production.

Strong programming skills in Python (preferred) or R, with expertise in libraries such as scikit-learn, TensorFlow, or PyTorch.

Proficiency in SQL and experience working with large datasets.

Hands-on experience with model lifecycle management, MLOps, or deployment frameworks.

Strong background in statistical modeling, machine learning, and data visualization.

Excellent communication skills, with the ability to present complex concepts to non-technical audiences.

Experience with Agile delivery and tools such as Jira and Confluence.
