  • Build and operate AI-first / agentic processes for the team's pipelines — designing the agent loop (context, tools, evals, guardrails) so agentic delivery is reliable, observable, and cost-controlled
  • Model financial and behavioural data into governed, documented datasets with clear ownership, lineage, and access controls aligned to GDPR and internal data governance
  • Embed data-quality and observability as first-class deliverables: freshness, completeness, distribution, and schema-drift checks with alerting
  • Maintain post-production accountability for owned pipelines — monitoring, incident response, root-cause analysis, and iterative improvement
  • Work with a feature store with point-in-time-correct data, using Databricks and Spark, with tracing for pipeline observability.
