About estaie

estaie is building the world’s first AI-native extended-stay platform.

We are not another OTA. We are building an intelligent hospitality system that learns from every booking - optimizing pricing, personalization, inventory intelligence, and operational decisions autonomously.

What You’ll Own

You will lead the design and deployment of the intelligence layer powering estaie.

From raw data to production ML serving, you will own the full lifecycle.

AI Architecture & Model Development

• Build and deploy ML pipelines on Vertex AI Pipelines
• Design pricing, recommendation, and personalization models
• Build autonomous agents using LangGraph + Vertex AI SDK
• Implement embeddings and semantic search with pgvector + Vertex Matching Engine
• Fine-tune and integrate LLMs such as Gemini, GPT, Claude
• Serve production models via NestJS APIs and Cloud Run

Data Engineering & Analytics

• Architect clean, scalable data models in BigQuery and dbt
• Build AI performance dashboards in Looker or Metabase
• Run A/B experiments with Statsig and PostHog
• Define and track AI KPIs such as pricing accuracy and extension prediction
• Ensure data governance across UAE, KSA, and EU regions

Leadership & Impact

• Mentor engineers and analysts on ML best practices
• Translate business problems into AI-first systems
• Contribute to long-term AI architecture and scalability planning

Tech Stack

AI & ML: Vertex AI, LangGraph, Gemini APIs, pgvector, scikit-learn

Data: BigQuery, dbt, Pub/Sub, Cloud Storage

Analytics: Looker, Metabase, Statsig, PostHog

Backend: NestJS, Cloud Run, Cloud Tasks

Languages: Python, SQL, TypeScript

Cloud: GCP Serverless Stack, Cloud DLP, Secret Manager

What We’re Looking For

• 5+ years in AI engineering, ML, or data engineering
• Strong Python and SQL skills
• Experience deploying ML pipelines in production
• Strong grasp of feature engineering and evaluation
• Experience with vector search and recommendation systems
• Understanding of experimentation and analytics
• Solid foundation in GCP and serverless infrastructure
• Bonus if you’ve worked with LangChain or LangGraph, or have experience in applied AI products.

Why Join?

You won’t be building dashboards for vanity metrics.

You will be building systems that decide pricing, optimize stays, and increase revenue autonomously.
