Data Scientist

As a Data Scientist, you will:

Design, develop, and productionise machine learning and statistical models.

Work with large-scale structured and unstructured datasets.

Perform exploratory data analysis to identify patterns, trends, anomalies, and opportunities.

Develop advanced feature engineering and data transformation pipelines.

Build predictive models using techniques such as regression, tree-based models, gradient boosting, ensemble modelling, clustering, ranking, and deep learning where appropriate.

Develop end-to-end ML pipelines covering data preparation, training, validation, deployment, scoring, and monitoring.

Conduct model backtesting, benchmarking, hyperparameter optimisation, and performance analysis.

Develop model explainability and interpretability using techniques such as SHAP and feature importance.

Monitor model performance, data drift, feature drift, stability, coverage, and production accuracy.

Develop scalable batch and real-time prediction pipelines.

Build reusable analytical frameworks rather than one-off solutions.

Design automated data-quality and model-quality checks.

Investigate production issues and perform root-cause analysis.

Identify opportunities to improve existing models, data pipelines, and analytical methodologies.

Work closely with Data Engineers and Software Engineers to move models from experimentation into production.

Translate business problems into measurable data science objectives.

Experience developing predictive models using real-world datasets.

Experience with feature engineering, model evaluation, and model optimisation.

Experience working with large and complex datasets.

Strong understanding of model validation and performance metrics.

Ability to translate business requirements into analytical and machine learning solutions.

Strong problem-solving and analytical skills.

Ability to communicate complex technical concepts to different audiences.

This role provides the opportunity to:

Work on complex, real-world machine learning problems with measurable business impact.

Build models using large-scale mortgage and real estate datasets.

Work with modern cloud and data platforms such as Snowflake and Databricks.

Own solutions across the complete machine learning lifecycle.

Build production systems rather than proof-of-concept models alone.

Experiment with traditional machine learning, advanced analytics, and Generative AI.

Collaborate with experienced Data Scientists, Engineers, Product teams, and domain experts.

Influence the architecture and direction of data science solutions.

Continuously learn new technologies and modelling techniques.

See your models and analytical solutions directly influence products and business decisions.
