Senior Data Engineer - Fintech Engineering (m/f/n)

Your role:

• Design, build, and operate batch and streaming data pipelines on the lakehouse (Databricks / Spark) that ingest, validate, and model data for credit origination, underwriting, and portfolio reporting
• Build and maintain the feature store that BNPL Origination and MCA Underwriting consume, guaranteeing point-in-time correctness, freshness SLAs, and reproducibility for every served feature
• 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.

You will own agentic harnesses and loop- and graph-based agent workflows around the feature store. You design the agent loop (context, tools, state, evals, guardrails) for feature creation, freshness, and data-quality monitoring.
