Join a purpose driven winning team, committed to results, in an inclusive and high-performing culture.

The Role

We are seeking a passionate and experienced Senior Data Scientist to implement various AI and Machine Learning Solutions. This is a unique opportunity to make a significant real-world impact by enhancing customer experiences and operational efficiency through innovative, data-driven solutions. You will play a pivotal role in the execution and implementation of next-generation AI systems. As a Senior Data Scientist, you will mentor and guide a talented group of data scientists, collaborating with experts from various fields, including data engineers, software developers, and business analysts, to apply LLM-driven and agentic AI solutions across data-rich banking operations.

Is this role right for you? In this role, you will be involved in:

Team Leadership and Mentorship:

  • Lead, mentor, and develop a high-performing team of data scientists, fostering a culture of innovation and collaboration.
  • Manage data science projects from conception to deployment, ensuring they are delivered on time and meet business requirements.
  • Provide technical guidance and oversight on the development and implementation of a diverse portfolio of analytics models, spanning both classical machine learning and generative AI.

Technical Strategy and Execution:

  • Determine the most effective AI/ML approach for various business problems, choosing between traditional models and generative AI solutions based on performance, cost, and interpretability requirements.
  • Oversee the end-to-end lifecycle of traditional machine learning models (e.g., for fraud detection, credit risk, and customer churn), from feature engineering and model selection to deployment, monitoring, and maintenance.
  • Lead the development and fine-tuning of traditional AI and ML models for diverse banking use cases.
  • Lead the implementation of conversational AI solutions, ensuring they deliver a seamless and intuitive user experience.
  • Drive the development of scalable and robust agentic architectures, enabling autonomous and intelligent decision-making within our AI systems.
  • Lead the deployment of Large Language Models (LLMs) for a wide array of banking applications beyond customer interfaces, such as automated content generation, risk assessment insights, and internal knowledge management.

Analysis and Insights:

  • Guide the analysis of interactions with LLM-powered agents and RAG systems to identify emergent patterns, user needs, and critical areas for performance optimization.
  • Generate and present actionable insights derived from both traditional and generative AI analysis to strategically inform senior management and drive business decisions.
  • Establish and oversee the evaluation of model performance using relevant metrics, developing strategies for model optimization and bias mitigation across all models.
  • Direct the continuous monitoring, updating, and re-training of all models to adapt to changing market dynamics and evolving data landscapes.

Documentation and Communication:

  • Maintain comprehensive documentation of data sources, model development (for both traditional ML and GenAI), and implementation processes.
  • Provide regular reports and updates on AI solution performance and project progress to senior management and stakeholders.
  • Work closely with cross-functional teams to seamlessly integrate cutting-edge AI solutions into core banking operations.
  • Effectively communicate complex technical findings, project progress, and strategic recommendations to both technical and non-technical stakeholders.

Governance and Quality Assurance:

  • Ensure all AI solutions, including traditional predictive models and generative systems, comply with banking regulations and ethical AI standards, with a focus on model explainability, fairness, and responsible use.
  • Oversee rigorous testing, validation, and quality assurance for all AI solutions to ensure accuracy, fairness, and a seamless customer experience.
  • Proactively identify and mitigate potential risks and challenges that arise during the development and deployment of advanced AI systems.

Do you have the skills that will enable you to succeed? We’d love to work with you if you have the following:

  • Master's or Ph.D. in Data Science, Computer Science, Statistics, or a related field.
  • Proven experience in a data science leadership role, with a track record of successfully leading and delivering data science projects.
  • Extensive experience in Python and its core data science libraries (e.g., Scikit-learn, Pandas, NumPy, Matplotlib/Seaborn) for data analysis, modeling, and scripting.
  • Strong expertise in SQL for data manipulation and querying.
  • Strong theoretical and practical knowledge of classical machine learning algorithms (e.g., classification, regression, clustering, dimensionality reduction) and their applications in areas such as fraud detection, credit ris
