What you'll do

  • Deliver machine learning models for planning products, iterating from initial prototype to evaluated and monitored production artefacts.
  • Explore innovative modelling and optimisation approaches, benchmarking and testing them rigorously against existing solutions.
  • Build and extend simulations of warehouse operations and customer demand to validate and power live operational plans.
  • Define and measure business-critical metrics using robust statistical techniques, establishing the team's standards for model evaluation.
  • Set the technical direction and delivery strategy for the data science initiatives you lead.
  • Develop the technical capabilities of data scientists across the team through mentoring, technical guidance, and collaboration.
  • Partner with software engineers to ensure models are cleanly packaged, deployed, monitored, and efficiently served on the platform.
  • Own relationships with product managers, internal partner teams, and external retailers to align on requirements and delivery roadmaps.

What we're looking for

  • Proven track record of taking data science and machine learning models into production, maintaining them, and leading initiatives end-to-end.
  • Strong machine learning and statistical expertise, including the ability to evaluate model performance rigorously against business metrics.
  • Fluency in writing production-quality Python code.
  • Experience querying and working with large datasets in cloud data warehouses such as BigQuery, including implementing data-quality checks.
  • Experience building simulations or stochastic models of operational systems.
  • Practical experience using AI coding agents, alongside the critical judgement to verify and test generated code and outputs.
  • Demonstrated ability to collaborate effectively with software engineers, product managers, and diverse business stakeholders.

Nice to have
