Build and productionise time series forecasting models for demand and stock perspectives; perform back-testing and continuously improve forecast accuracy
Partner with stakeholders to define success metrics and deliver meaningful outcomes
Build, validate and optimise robust data pipelines and model code (testing, performance, reproducibility, documentation and security considerations)
Contribute to team growth through knowledge sharing, mentoring, and best practice

Essential experience:

Demonstrated ability to solve ambiguous problems and deliver end-to-end analytical solutions
Strong grounding in applied statistics (hypothesis testing, experiment design, uncertainty analysis)
Proven experience with both static and time series modelling
Advanced skills in Python, SQL, and PySpark, with a focus on clean, testable, reproducible code
Experience deploying models in cloud environments (Azure preferred), including CI/CD and monitoring
Strong communication skills—able to simplify complex ideas for non-technical audiences
PhD or Masters Degree

Experience with tools such as MLflow, PyTorch, Databricks, or graph databases
A passion for continuous improvement and sharing knowledge
A collaborative mindset with excellent stakeholder engagement skills
