Role Overview The AI Engineer will develop document-AI pipelines, LLM prompts, Retrieval-Augmented Generation (RAG) solutions, and evaluation datasets for enterprise applications. The role includes processing scanned and digital documents, extracting and classifying information, improving retrieval quality, and integrating AI services with OutSystems through APIs.

Candidates must have at least 1 year of hands-on LLM/RAG development experience and demonstrate working solutions with measurable outcomes.

Key Responsibilities

- Build document-processing pipelines for extraction, classification, and information retrieval.
- Develop RAG pipelines using embeddings, vector databases, and LLM APIs.
- Create, test, version, and maintain prompts and prompt templates.
- Build evaluation datasets to measure answer accuracy and consistency with source documents.
- Process scanned PDFs using OCR and other document-processing services.
- Tune retrieval strategies, chunking, embeddings, and ranking to improve answer relevance.
- Expose AI capabilities through REST APIs for integration with OutSystems applications.
- Write automated tests and evaluate AI-generated responses against source documents.




- Monitor pipeline performance and improve the reliability of AI outputs

Mandatory Skills & Experience
