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.
