Data Scientist

Apply for the Data Scientist
Location: Slough
Job Description:

Were looking for a graduate data scientist to help build and exploit a digital twin of every block of flats in the UK — a single, structured, continuously updated model of the buildings we insure and the ones we might.

Youll do two things. First, help build the data foundation: bringing together public and commercial datasets and resolving them to individual buildings. Second — and increasingly over time — use that data to understand the true risk of each building and turn it into pricing, risk selection and insight we give back to clients.

Initially, this is a three month role with the potential to become full time.

This is a rare chance to own foundational work from day one at an early-stage company, with real scope to shape both the data and the models built on it.

What youll do

  • Help build and maintain the digital twin — ingesting, cleaning, matching and enriching building-level data from multiple sources.
  • Work with UK datasets including Ordnance Survey (e.g. AddressBase, building footprints), Land Registry, EPC records, planning data, flood and other peril data, and commercial sources.
  • Solve entity resolution — reliably matching records across datasets to the right physical building and address.
  • Analyse and model risk at building level — identifying the features that actually drive claims and turning them into signals for pricing and underwriting.
  • Build, test and validate models, and clearly communicate what they do and dont tell us.
  • Work with large databases and keep them accurate and performant as they grow.
  • Help define what “good” looks like — data quality, coverage, model performance — and build the checks to enforce it.

Why join

  • Real ownership — youll shape a core company asset and the models built on it, not maintain someone elses legacy system.
  • Equity — share in what were building.
  • Direct impact — your work shapes how we price risk and what we tell clients.
  • Learn fast — work directly with the founder and a small, senior team.
