Role Overview

We are seeking a Data Scientist who can turn statistical ideas into models that loyalty clients rely on every day. You will build predictive and causal models on member-level data from programs with millions of members, run them reliably in production, and explain their impact to client stakeholders.

The role is roughly 70% technical (modeling, statistics, engineering of ML systems) and 30% business (framing problems, working with clients, translating results into decisions). You will work closely with Product, Data Engineering, Engineering and Customer Success.

What you will OWN

Predictive & Statistical Modeling (technical)

Design, train and validate models for churn, propensity, next-best-offer, lifetime value, tier migration and anomaly or fraud detection. Choose methods on evidence: regression and GLMs, survival analysis, gradient boosting, probabilistic and Bayesian models, time-series forecasting, and deep learning where it earns its complexity.

Experimentation & Causal Inference (technical)

Design A/B tests and holdouts for campaigns, offers and program changes, including power analysis and sample sizing. Apply uplift modeling and causal methods (diff-in-diff, propensity matching) to measure the true incremental impact of loyalty initiatives when randomization is not possible.

Feature Engineering & Data Pipelines (technical)

Build and maintain reusable featuresets from large transactional and behavioral datasets. Work with Data Engineering on data quality, lineage and scalable processing in the data warehouse and cloud platform.

Client Engagement & Insight Delivery (business)

Partner with client stakeholders to frame business questions as modeling problems, define success metrics, and present results and recommendations in executive reviews. Translate model outputs into clear actions for marketing, product and finance teams, and document models, assumptions and limitations.

To be successful in this role, you should have:

• Bachelor's or Master's degree in Statistics, Mathematics, Computer Science, Engineering, Data Science or a related quantitative field. An MBA or a postgraduate degree in Analytics is an added advantage.
• 1–4 years of experience building and deploying ML or statistical models in production, ideally in a SaaS, consumer or loyalty/CRM setting.
• Strong Python (pandas, NumPy, scikit-learn, XGBoost/LightGBM, statsmodels; PyTorch or TensorFlow is a plus) and strong SQL.
• Solid statistical foundations: hypothesis testing, regression, probability, Bayesian methods, time-series, survival analysis and experimental design.
• Experience with cloud data platforms such as Snowflake, BigQuery, Redshift, Databricks or Vertica, and with large-scale data processing (Spark is a plus).
• Working knowledge of a BI tool (Tableau, Power BI, Looker or similar) to share model outputs.
• Experience with causal inference or uplift modeling is preferred.
• Exposure to enterprise SaaS products or customer loyalty programs is preferred.
• Strong communication skills: able to explain model logic, trade-offs and uncertainty to non-technical stakeholders.
• Understanding of Agile methodologies and comfort working in a fast-paced environment.

Key Competencies

• Statistical Modeling & Machine Learning
• Experimentation & Causal Thinking
• Production-Grade Engineering & MLOps
• Problem Solving & Root Cause Analysis
• Business Problem Framing
• Stakeholder Communication & Data Storytelling
• Attention to Detail & Reproducibility
• Collaboration & Ownership

Why join us?

• Build ML that runs on loyalty programs serving 400+ million members
• Own models end to end, from research through production
• Work on real modeling problems: churn, uplift, forecasting and program economics
• Collaborative, innovative environment with direct exposure to global brands
• Strong growth and learning opportunities within a rapidly expanding organization
