Job description

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., * 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., We care more about how you think than whether you've used every tool.
  • Backend: Node.js
  • Data: PostgreSQL (+ optional graph or vector extensions)
  • Ingestion: Playwright / similar scraping approaches
  • Analytics & AI: ML for signals and anomaly detection
  • LLMs: agentic workflows, tool-using LLMs, optional MCP
  • Frontend: Angular/React
  • Infra: Cloud (AWS/GCP), Docker, CI/CD

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