Position Title:
Senior AI Engineer
Location:
LATAM
What you will be doing:
Building a Data Warehouse that consolidates (property/appraisal data - comps, valuations, market data, inspection records, etc.). We're hiring an AI Engineer to build the intelligent interface on top of it: a system that lets our team and product query that data in natural language and get answers they can trust.
We currently use Claude for appraiser-facing questions,



and while it's strong at general reasoning, it hallucinates on domain-specific appraisal questions because it isn't grounded in our data. Your core mission is to fix that - to make our AI answer appraisal questions accurately, with answers traceable back to real data in our warehouse.
This is a hands-on, applied role for someone who understands modern LLM engineering (retrieval, grounding, evaluation) and knows how to connect a model to a live data source without letting it make things up.
- Build and own the interface between our LLM and the Data Warehouse - enabling natural-language and structured querying of appraisal data.
- Design and implement retrieval / RAG pipelines that ground model responses in real warehouse data, so answers are accurate and citable rather than invented
- Diagnose and reduce hallucination on appraisal-specific questions through better retrieval, prompt engineering, guardrails, and output validation.
