About the role

At Reckitt, we are transforming how we drive revenue growth through advanced analytics and our in-house product, RGMx. This is not a typical data science role - you will directly shape how pricing, promotions, and commercial decisions are made across markets.

We are seeking a skilled and innovative Senior Data Scientist who will be responsible for developing and enhancing the methodologies and algorithms that power our framework. You will play a key role in evolving our RGMx product, developing cutting-edge methodologies, and turning complex data into actionable strategies that drive measurable business impact. You will work at the intersection of data science, technology, and commercial strategy - partnering with cross-functional teams to push the boundaries of revenue growth management.

Your responsibilities

Develop and implement advanced statistical and machine learning methodologies to improve the accuracy and effectiveness of the RGMx tool in alignment with priorities.
Continuously test, validate, and refine models to ensure robustness, reliability, and business relevance.
Design and build scalable data science solutions using Python, PySpark, SQL (optionally R or Julia).
Work with modern cloud platforms such as Microsoft Azure and Databricks, integrating multiple data sources and optimizing data pipelines.
Monitor and improve model performance in production, ensuring scalability and long-term sustainability (experience with MLOps, including CI/CD, model versioning).
Collaborate with cross-functional teams to design, develop, and enhance the RGMx tool, ensuring it meets the needs of our stakeholders and translate complex business challenges into scalable data science solutions.
Ensure high standards of code quality and maintainability by writing clean, modular, and maintainable code, and actively contributing to code reviews and engineering standards.
Establish and promote consistent ways of working across the team, including coding standards, reproducibility, and documentation practices.
Contribute to defining the right technology stack and algorithmic approaches for scalability, efficiency, and performance.
Create clear and impactful visualizations and data products (dashboards, presentations) to communicate insights to both technical and non-technical audiences.
Document methodologies, processes, and outputs to ensure transparency, reproducibility, and knowledge sharing
Stay up to date with the latest developments in data science, machine learning, and revenue growth management to continuously improve the RGMx tool.
Leverage deep understanding of FMCG market dynamics and sell-out (POS) data to ensure models reflect real-world behavior across pricing, promotions, assortment, and channels.

The experience we're looking for

2+ years of experience applying advanced analytics to real-world business challenges (pricing, sales, revenue optimization), from prototype to measurable impact.
University Degree in Data Science, Computer Science, Econometrics, Mathematics, or a related quantitative discipline.
Solid understanding of machine learning techniques (regression, classification, time series, clustering, explainable AI) and their practical application.
Proficiency in Python (pandas, NumPy, scikit-learn, XGBoost, LightGBM, statsmodels) and strong SQL skills for working with complex datasets.
Experience with cloud and big data environments (e.g., Microsoft Azure, Apache Spark) and familiarity with MLOps tools (MLflow, Airflow).
Good knowledge of software engineering best practices, including Git, testing, and CI/CD pipelines.
Ability to translate complex analytical outputs into clear, actionable insights for non-technical stakeholders.
Experience working in Agile, cross-functional teams and collaborating with business and technical functions.
Proactive, curious, and ownership-driven mindset with a strong focus on quality and continuous improvement.
Understanding of FMCG market dynamics and experience with POS (sell-out) data, including pricing, promotions, and assortment challenges

You’ll love it because…

It is a unique opportunity to shape how data and advanced analytics drive commercial decisions across markets—directly influencing pricing, promotions, and growth for globally recognized brands.
Work deployed into real business processes, driving tangible impact and powering decisions used daily across the organization.
High level of ownership and autonomy, with the ability to turn ideas into scalable products.
Collaboration with talented, cross-functional teams in an international environment.
An ownership-driven culture that invests in growth, challenges boundaries, and supports doing your best work.
