You always find a way to get things done without sacrificing the quality of your work, integrity, and values

No task is off limits for you

You are humble and prioritize the success of the team over your own with an eagerness to help those around you

You don't shy away from challenges and can bounce back from setbacks

Design, develop, and enhance predictive models, pricing solutions, recommendation engines, and automation tools to support a range of banking products and services

Perform deep-dive analysis on large and complex datasets to identify trends, patterns, and key features that improve model performance and business outcomes

What we’re looking for:

Bachelor’s or Master’s degree in Computer Science, Data Science, Statistics, Mathematics, or another relevant quantitative discipline

3 to 5 years of hands-on experience in Data Science, Machine Learning, or a related analytical role

Strong proficiency in Python and SQL, with hands-on experience using machine learning frameworks and libraries such as Scikit-learn, XGBoost, TensorFlow, or PyTorch

Practical experience with Spark/PySpark or other big data technologies for processing and analyzing large-scale datasets

Familiarity with cloud-based machine learning platforms such as AWS SageMaker or Google Cloud Vertex AI, together with exposure to MLOps tools and practices such as MLflow and Git

Strong analytical and problem-solving skills, with the ability to work through ambiguity and translate complex data into practical solutions.
