Description

Data Engineer — RMS Ingestion & Schema Layer

📍 Hybrid with occasional London travel (fully expensed)

💰 Up to £80,000 + potential equity

We’re working with a genuinely mission-led tech business building next-generation investigative platforms, and they’re looking for a Data Engineer to own one of the most critical parts of their product.

This isn’t just another ETL role. You’ll sit at the heart of a complex data ecosystem, shaping how raw, disparate records become structured, usable intelligence that directly supports real-world investigations.

The role

You’ll take ownership of ingesting and normalising data from legacy RMS platforms such as Niche and Athena into a modern, unified system. A key part of your work will be designing and maintaining the schema reconciliation layer, as well as building the pipelines that connect CAD, RMS and investigative logs into a coherent event sequence model.

Put simply, you’ll be solving messy, high-impact data problems that most teams never get near.

What you’ll be doing

  • Building robust ETL pipelines to extract and transform data from legacy systems
  • Designing schema mapping and reconciliation layers across multiple data sources
  • Developing event-sequence and temporal data models (CAD → RMS → investigation pipelines)
  • Working with highly sensitive datasets, ensuring privacy, security and integrity at all times
  • Supporting the evolution of a core platform dependency that underpins the entire product

What they’re looking for

  • Strong experience in ETL workflows and data pipeline engineering
  • Proven background in schema design, mapping and reconciliation
  • Experience working with sensitive data (PII, health, or similarly regulated datasets) — this is essential
  • A solid understanding of temporal or event-driven data modelling

Nice to have (but not essential)

  • Experience building UI-based ingestion tools where APIs aren’t available
  • Exposure to video or streaming data pipelines

Why it’s worth a conversation

  • Salary up to £80,000 with potential equity
  • Real ownership of a critical product component
  • Work on complex, meaningful problems with genuine societal impact
  • Occasional travel to London (all expenses covered)
  • A chance to shape how a cutting-edge platform is built from the ground up
