  • Developing high-performance data pipelines and processing frameworks using Python, Scala, Spark and Databricks.
  • Owning and evolving platform components that help engineers and data scientists build, test, deploy and monitor data products.
  • Improving platform reliability, observability, data quality and operational excellence.
  • Creating reusable libraries, tooling and engineering patterns that enable teams to deliver data products more efficiently.
  • Partnering with Data Scientists, ML Engineers and Product Engineering teams to solve data challenges and enable new machine learning use cases.
  • Contributing to architectural decisions and the evolution of data engineering standards across the organisation.
  • Optimising distributed workloads for performance, scalability and cost efficiency across the Azure ecosystem.
  • Supporting the long-term development of ASOS's data platform and engineering practices.
  • Working with multiple Data Science and Machine Learning teams across ASOS to deliver platform capabilities that create business value.
