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. 

 

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. 

 

Qualifications

Must-Have Skills & Experience 

  • 3+ years in backend software development.

  • Proficient in Python; FastAPI or Flask experience preferred.

  • Experience with AWS serverless and container services: Lambda, ECS, API Gateway. 

  • Experience with DynamoDB / S3.

  • Familiarity with SSO/OAuth 2.0/OIDC patterns; AWS Cognito or equivalent identity provider integration experience. 

  • Understanding of API design principles, audit logging patterns, and secure data handling. 

  • Comfortable working in agile/scrum teams with Jira. 

Additional Information

Nice-to-Have 

  • Exposure to RAG or LLM-integrated backend systems working alongside AI pipeline components. 

  • Experience with multi-tenant application architecture and tenant-scoped access control patterns. 

  • Familiarity with structured audit logging for compliance or regulated-data use cases.
