Role Description 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. Qualifications - +90% English written and oral (at least B2 level) with excellent communication skills - 6+ years in software development; minimum 2 years in a tech lead or senior engineering lead capacity - Strong Python development skills; FastAPI or equivalent async Python framework required - Hands-on AWS experience: ECS and/or Lambda, API Gateway, DynamoDB, S3, CloudWatch, X-Ray - Experience with vector databases OpenSearch, Pinecone, Weaviate, or equivalent - Solid understanding of API design, service decomposition, and clean backend architecture - Delivered at least one production RAG, semantic search, or LLM-integrated application end-to-end, not a prototype or internal tool - Practical experience integrating with LLM provider APIs (OpenAI, Anthropic, or Amazon Bedrock) in a production or enterprise configuration - Working knowledge of chunking strategies, embedding models, retrieval ranking, and prompt engineering in a production context - Experience with confidence scoring, retrieval evaluation, or hallucination mitigation approaches in a deployed system - Experience with LangChain, LlamaIndex, or similar LLM orchestration frameworks (Nice to have) - Familiarity with OCR pipelines and document extraction tooling (AWS Textract, Tesseract, or equivalent - Nice to have) - Exposure to multi-tenant data isolation patterns and tenant-scoped encryption key management (Nice to have) Requirements - 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 Benefits - Educational resources - Flexible schedule and Work From Anywhere - Referral Program - Supportive and chill atmosphere - Trajectory recognition plan
