AI / LLM Engineer · Mid-level
Curitiba, Brazil
I ship GenAI into real operations. RAG, multi-tool agents, and production software Open to full-time employment (CLT) or a contractor agreement (PJ), based in Curitiba.
About
I'm Felipe P. dos Santos, an AI engineer at Grupo Boticário. Before that I led engineering at a startup and founded a B2B SaaS. The thread is the same: take a spreadsheet process and turn it into software a team actually uses.
I'm looking for an AI engineering team, either as a CLT employee or as a PJ contractor. The fit is production GenAI: grounded retrieval, tool-using agents, and operational automation. Degree in Systems Analysis and Development, plus CS50x, AWS Cloud Foundations, and the Desenvolve program.

Grounded retrieval over technical and operational documentation. The model answers from the company's material, not from loose memory.
