Principal Data & ML Engineer (Founding Role)

AI-Native Real Estate Intelligence Platform

📍 Remote (Europe) | 🌱 Seed / Idea Stage | 🇺🇦 Ukrainian is a plus



🚀 The Opportunity

We’re building the intelligence layer for the real estate market

This is not a listings platform and not a document search tool. Our product turns large volumes of messy, unstructured property data into structured market intelligence: trends, anomalies, and investment-relevant signals

As our first engineering hire, you’ll own the technical foundation from 0→1 — designing the data platform, ML pipelines, and system architecture that everything else will be built on


🧠 What You’ll Own

  • Design and build data ingestion pipelines for unstable, anti-bot-protected web sources
  • Create a normalized data layer that connects property information across thousands of sources
  • Build ML / analytics pipelines to compute market signals and detect anomalies
  • Use LLMs as a reasoning and interface layer on top of structured data (not as the core system)
  • Make architectural decisions end-to-end: data models, pipelines, services, infra
  • Work directly with the founders on product and technical direction

Lay the groundwork for future engineers and grow into a technical leadership role


✅ What Matters Most (Core Requirements)

  • We care much more about technical maturity and system thinking than a specific stack.
  • Strong experience building production systems from scratch (0→1)
  • Deep comfort with data-heavy systems and unstructured inputs
  • Practical understanding of ML / analytics pipelines (feature generation, evaluation, iteration)
  • Ability to think in systems, data flows, and trade-offs — not just APIs

Hands-on mindset: you design it and you build itInterest in early-stage work with high ownership and low bureaucracy⚠️

This is not a research role and not a pure AI automation role.


  • 🧩 Current Technical Direction (Flexible)This reflects our current thinking — not a strict checklist.
  • Backend / Platform: flexible (Node.js, Python, or similar)
  • Data Layer: PostgreSQL (with possible graph / vector extensions)
  • Ingestion: Playwright or similar scraping approaches
  • ML / Analytics: signal extraction, anomaly detection, feature pipelines
  • LLMs: reasoning & interface layer, agentic workflows where useful
  • Frontend: React / Angular

Infra: Cloud (AWS / GCP), Docker, CI/CDWe care about why you choose tools, not whether you’ve used ours.


⭐ Nice to Have

  • Experience as a founding or early-stage engineer
  • Knowledge graphs or complex data models

Background in PropTech, FinTech, or market intelligence products


⚠️ Important Note


We don’t expect one person to permanently cover every layer.Your initial focus will match your strengths, and we’ll hire around you as the platform grows.
