Desenvolvedor de back end

Realitade is building a AI-native real estate technology ecosystem for Europe, starting in Portugal.

The goal is to connect properties, professional services, AI-powered workflows, investment intelligence, and trusted transaction into one ecosystem.

We are looking for founding-level people who understand, or are committed to deeply learning, how the real estate market works from A to Z: buyers, sellers, agents, developers, architects, construction companies, lawyers, investors, banks, regulation, transactions, and cross-border expansion.

This is not a place for isolated individual contributors. We need people who communicate clearly, challenge ideas constructively and collaborate with an open-mind with co-workers.

We are looking for a Backend Engineer to build the core systems behind a complex real-estate platform.

Responsibilities:

• Build and maintain APIs, backend services, business logic, data models, and workflow systems;
• Integrate LLMs and external AI APIs;
• Implement RAG pipelines, embeddings, and vector search;
• Integrate external services such as CRMs, payment systems, AI providers, and real-estate data sources;
• Write automated tests, and optimize performance;
• Ensure application security, monitoring, and scalability;
• Collaborate with AI, frontend, product, and business teams.

Requirements:

• Strong backend engineering experience and object-oriented thinking;
• Strong experience with TypeScript/Node.js, Python, Go, Ruby on Rails, PHP, or similar backend stacks;
• Experience with Langchain, redis, vector databases, PostgreSQL, Docker, Git, CI/CD pipelines, and production systems;
• Ability to understand complex business logic;
• Strong problem-solving, clear communication, team mindset, and openness to discussing architecture and product tradeoffs;
• Portugal-based or willing to spend significant time in Portugal is MANDATORY.

Compensation:

This is an equity-based founding or early leadership position, not a conventional salaried role at this stage. The selected candidate may receive an agreed ownership stake in the company. For senior leadership roles, the position may include a CTO, COO, Head of AI, or other leadership title depending on profile and responsibilities.

A board seat may be considered subject to legal formalities.

The company will actively target funding so the team can focus on engineering, product development, and market execution. A salary may be introduced after defined funding or revenue milestones are reached.
