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.
Your Responsibilities
Build and maintain the BFF/Backend API layer (Python/FastAPI, ECS/Lambda).
Implement SSO / identity provider integration and the tenant-based authentication schema (AWS Cognito).
Build the audit logging layer, from minimal dev logging through to full document lifecycle tracking.
Develop core API services supporting the chat Q&A interface and retrieval orchestration.
Integrate with AWS services: API Gateway, Cognito, DynamoDB, S3, CloudWatch.
Write unit and integration tests; support the QA Automation Engineer with testable, documented service contracts.
Participate in code reviews and contribute to maintaining backend code quality standards alongside the Tech Lead.
Tech Stack: Python, FastAPI, AWS Lambda, ECS, API Gateway, Cognito, DynamoDB, S3
