Requirements
  • 6+ years building production software in Python, with strong engineering fundamentals (testing, performance, clean design)
  • Solid data engineering: SQL, columnar formats (e.g. Parquet), pipeline design, and handling datasets large enough that naive approaches don't scale
  • Hands-on experience with at least one analytical or query engine (e.g. DuckDB, Trino, Spark, ClickHouse)
  • Real experience building LLM / agent applications: retrieval (RAG), vector databases, and tool / function calling
  • A working understanding of data governance: cataloguing, metadata, lineage, and access control (RBAC / ABAC)
  • An instinct for data quality and trustworthy 'golden' sources
Job Responsibility
Job Responsibility
  • Build production-grade Python services and data pipelines over large data stores (columnar / time-series and relational), and the queries that join across them
  • Select and implement the right query or analytical engine for each workload, rather than defaulting to one
  • Build catalogue, metadata, lineage and semantic layers that make data discoverable and consistently understood across teams
  • Implement access control that travels with the data: fusing sensitivity and licensing scope, enforced at the point of use, including for AI agents
  • Build agent-facing data access: retrieval (RAG), vector search, and APIs / MCP servers, with permissions applied before context reaches the model
  • Apply LLMs pragmatically to data work (metadata generation, classification, entity resolution) with humans in the loop and evaluate the quality of what the agents produce
  • Help keep data trustworthy: establish golden sources, deduplication and data-quality checks at the source
  • Contribute to discovery and solutioning: assessing current state, weighing build-vs-adopt, and shaping pragmatic, costed plans
