Job Description

We’re building the intelligence layer for the real estate market. Our platform automatically discovers, normalizes, and analyzes property data from thousands of unstructured, real-world web sources. The goal is not listings or document search - but structured market intelligence: trends, anomalies, and investment-relevant signals. As our first engineering hire, you’ll design the core architecture from 0→1, build the data and intelligence foundation, and grow into a technical leader as the team scales.

Job Responsibility

  • Design and build a scalable data ingestion system for messy, anti-bot-protected sources
  • Create a centralized data / knowledge layer that normalizes and connects property information across sources
  • Develop an analytics & ML layer to compute market signals and detect anomalies
  • Use LLMs as an interface and reasoning layer on top of structured data and computed metrics
  • Work directly with the founders on product decisions and technical direction
  • Establish engineering standards and help scale the team over time

Requirements

  • Strong experience building production systems from scratch
  • Solid backend, frontend and data engineering background (language-agnostic)
  • Comfort working with unstructured data and unstable sources
  • Practical understanding of ML / analytics pipelines (not research-heavy)
  • Experience using LLMs in real systems (beyond simple API calls)
  • Ownership mindset and interest in early-stage, high-impact work

Nice to have

  • Experience as a founding or early-stage engineer
  • Knowledge graphs or complex data models
  • Work in PropTech, FinTech, or market intelligence products
  • Ukrainian is a plus
