Company Description
WHAT YOU’LL DO
The Markdown Retail (MDR) team builds the models and pipelines that decide when and how much to discount articles during sale, across our stores and markets. These decisions affect sell-through and revenue in every market we operate in and frees up space for new collections. As a Senior Data Scientist on the team, you will work on this problem end to end, from the data and the model to the decision it drives in production, with a direct impact on business outcomes. You'll also help shape how we use agentic AI to run experiments and move faster toward that goal.
More specifically you will:
- Own and contribute to data science initiatives end to end, from understanding problem statements and exploring data to building, deploying, and maintaining models in production.
- Design, deploy, and operate machine learning models and pipelines in production on GCP (Vertex AI), with responsibility for evaluation, monitoring, and continuous improvement
- Apply statistical methods, machine learning, and advanced analytics to support product and business decisions.
- Develop, test, and improve models and data‑driven solutions with a strong focus on quality, scalability, and long‑term maintainability.
- Take responsibility for solutions after deployment, including monitoring, troubleshooting, and iterative improvements.
- Perform exploratory and ad hoc data analysis, and present insights in a clear and structured way.
- Work closely with business experts and product manager to translate business needs and help building a product roadmap.
- Contribute to technical standards, best practices, and knowledge sharing within the data science and ML community.
WHO YOU’LL WORK WITH
You will work in a cross‑functional team together with colleagues in product, engineering, analytics, and business roles. You will also be part of a broader Data Science and ML community, collaborating with other data scientists and ML engineers to share knowledge, align on best practices, and continuously improve how data science, ML and agentic AI is applied across the organization.
