The Opportunity We are looking for a

Mid-Level GenAI / Agentic AI Engineer

to design, develop, and deploy production-ready artificial intelligence solutions powered by Large Language Models and agentic architectures.

You will contribute to innovative projects in the energy sector, building intelligent workflows, RAG and Graph RAG solutions, evaluation frameworks, and integrations with enterprise data platforms.

Key Responsibilities

Design, develop, and deploy applications powered by LLMs;

Build AI agents and multi-step agentic workflows;

Develop and orchestrate AI workflows using LangGraph;

Design and implement RAG and Graph RAG architectures;

Create evaluation frameworks for quality, accuracy, reliability, and performance monitoring;

Integrate AI solutions with enterprise data sources, PostgreSQL, vector databases, and vector search platforms;

Develop maintainable, testable, and production-grade applications in Python;

Support the deployment, operation, monitoring, and continuous improvement of GenAI solutions;

Collaborate with engineering, data, product, and business teams;

Translate business needs into practical and scalable AI solutions.

Mandatory Requirements

At least three years of relevant professional experience;

Practical experience with Large Language Models;

Strong Python development skills;

Hands-on experience with LangGraph;

Experience designing AI agents or Agentic AI solutions;

Knowledge of RAG and Graph RAG architectures;

Experience building AI evaluation frameworks;

Knowledge of PostgreSQL;

Experience with vector databases or vector search;

Ability to develop solutions suitable for production environments;

Experience taking GenAI products from proof of concept to production.

Ideal Candidate Profile The ideal candidate combines strong Python engineering skills with practical knowledge of modern GenAI architectures. You understand that delivering an LLM solution involves more than writing prompts: it requires orchestration, retrieval, evaluation, monitoring, integration, and operational reliability.

You are analytical, pragmatic, and comfortable solving ambiguous problems. You can discuss technical decisions clearly with engineers while also explaining the business value, limitations, and risks of AI solutions to non-technical stakeholders.

You enjoy working collaboratively, take ownership of deliverables, and are motivated by the opportunity to build AI products that move beyond experimentation into reliable production use.

Why Consider This Opportunity?

Work on innovative GenAI and Agentic AI initiatives;

Build solutions with LLMs, LangGraph, RAG, and Graph RAG;

Participate in the complete AI product lifecycle, from design to production;

Solve relevant challenges within the energy sector;

Collaborate with multidisciplinary technical and business teams;

Benefit from a flexible hybrid working model;

Work from Lisbon or Porto.
