Data Scientist

About the job:

Position Overview:

We are seeking a skilled Modeler to contribute to the development and optimization of marketing analytics models.

You will work within a cross-functional team to build propensity models, next-best-action (NBA) engines, customer segmentation frameworks, and campaign response models that power data-driven marketing strategies.

You will apply best practices in model explainability, fairness testing, and lifecycle governance to ensure high-quality, compliant model outputs.

Key Responsibilities:

- Develop and optimize propensity models, segmentation frameworks, and campaign response models using supervised and unsupervised machine learning techniques.

- Conduct bias testing and implement model explainability methods (e.g., SHAP, LIME) to support model approval and governance workflows.

- Perform exploratory data analysis and feature engineering to identify meaningful predictors of customer behavior.

- Support the full model lifecycle including development, documentation, validation support, performance monitoring, and periodic re-validation.

- Collaborate with marketing and data teams to understand business objectives and translate them into modeling requirements.

- Prepare clear, concise model documentation including methodology overviews, performance summaries, and limitation disclosures.

- Monitor deployed models for data drift, performance degradation, and champion-challenger evaluation.

- Contribute to A/B test design and campaign measurement analyses to evaluate marketing effectiveness.

- Stay current on advances in marketing data science, uplift modeling, and customer analytics.

Qualifications & Experience:

- 3 - 6 years of experience in data science, analytics, or quantitative modeling with a focus on customer or marketing analytics.

- Hands-on experience building and evaluating classification and regression models for propensity scoring or segmentation.

- Proficiency in Python with working knowledge of libraries such as scikit-learn, XGBoost, LightGBM, pandas, and numpy.

- Familiarity with model explainability tools (SHAP, LIME) and basic concepts of model fairness and bias testing.

- Experience with SQL and large-scale data platforms for data extraction and feature preparation.

- Understanding of model validation principles and documentation standards.

- Strong analytical and problem-solving skills with attention to detail.

- Effective written and verbal communication skills for presenting model results to both technical and business stakeholders.

- Bachelor's degree (Master's preferred) in Statistics, Mathematics, Computer Science, Engineering, or a related quantitative field.

Model Lifecycle & Governance:

This role supports end-to-end model lifecycle management.

Responsibilities encompass model development, independent validation and assessment, performance optimization, monitoring, documentation, and governance - ensuring all models adhere to applicable standards and remain fit-for-purpose throughout their operational life.
