Job Description

About the Project Software Mind is building a private, tenant-isolated AI assistant for the real estate title and settlement industry. The platform is a retrieval-first (RAG) system that ingests historical email, documents, and structured metadata into a per-tenant vector index, and serves grounded, cited, expert-weighted answers through a chat-style Q&A interface with single sign-on and full audit logging. The platform is AWS-native with a Python/FastAPI backend, Vue.js frontend, OpenSearch/Pinecone vector store, and OpenAI/Anthropic/Bedrock as LLM provider. You will join a senior, cross-functional LATAM-based team where hands-on AI delivery experience not just familiarity is the baseline expectation. You are the technical delivery lead the bridge between architectural intent and day-to-day engineering execution. You own code quality, technical decisions within the team, and the delivery of the core AI Extraction Gateway (Simple and Complex RAG). You are hands-on: coding, reviewing, and unblocking across the Python backend and retrieval layers. Your Responsibilities Lead hands-on development of the AI Extraction Gateway, progressing from Simple RAG to Complex RAG Implement and tune the expert-weighted (SME) retrieval layer and structured result validation Own confidence score calibration; collaborate with the BA on accuracy rubrics and test evidence Drive technical delivery cadence: sprint planning, code reviews, technical risk identification, and team unblocking Ensure architectural patterns are implemented consistently across the codebase Collaborate with the Data Engineer on ingestion pipeline integration points and vector store schema Implement and evolve the query orchestration layer (Python/FastAPI, AWS Lambda/ECS) Support the QA Automation Engineer in designing the validation harness for RAG outputs Maintain development observability: structured logging, CloudWatch dashboards, X-Ray tracing Tech Stack: Python, FastAPI, AWS (ECS, Lambda), OpenSearch, Pinecone, OpenAI, Anthropic, Bedrock, DynamoDB, S3, CloudWatch, X-Ray, Docker, Jira, Confluence.
