- Support experimentation and testing: experiment monitoring, reads, and promotion calls
- Handle member support and regulatory pulls: DSAR and RTBF requests, complaint data, FCA regulatory returns, and marketplace-ranking monitoring, often against same-day or next-morning deadlines
- Represent analytics in forums and business reviews, and translate technical detail for business partners
- Maintain the current suite of production models: scheduled refreshes, retraining, and redeploys. Keep models healthy without rebuilding them
- Run data quality on model inputs and pipelines. Triage feed and pipeline issues
- Hand over models, pipelines, and reporting with monitoring and documentation to the permanent team at contract close
