Data/AI | Build the Data Layer

Our client is building a system where AI can reason over complex data - but that only works if the underlying data is deep, structured, and trustworthy.

They’re hiring a Founding Data Science Engineer (Evidence Depth) to build that layer.

This role is about going beyond “more data” - it’s about deciding what data matters, how it’s structured, and how AI can actually trust it.

What You'll Do

  • Own deepening the data layer within existing domains
  • Design how new data types are ingested, structured, and validated
  • Build AI-driven ingestion pipelines across multiple source types (documents, filings, web data, etc.)
  • Define how data is represented: entities, relationships, provenance, uncertainty
  • Create systems that make every data point traceable back to its source
  • Build evaluation loops to ensure extraction quality (accuracy, consistency, reliability)
  • Design workflows for human review and validation where needed
  • Ensure the data supports accurate reasoning and comparison downstream

What They Want

  • You can take messy, unstructured data and turn it into clean, usable systems
  • Strong instincts for data modelling and structure
  • You care about data quality, traceability, and correctness
  • You don’t blindly trust AI outputs - you design systems to validate them
  • You think about how data will actually be used downstream, not just stored
  • You can build what you design

Nice to Have

  • Experience with data engineering, ML systems, or AI pipelines
  • Exposire to extraction workflows, structured outputs, or knowledge graphs
  • Familiarity with evaluation frameworks or data quality systems
  • Experience working with complex, messy, or high-stakes data

Why this Role

  • Own the foundation of the system's intelligence
  • Direct impact on whether outputs are correct and defensible
  • Work at the core of data, AI, and real-world decision making 

What it's Not

  • Not just loading data
  • Not a generic pipeline role
  • Not frontend
  • Not infra ownership
