We are building a unified, high-touch operational platform for a premier luxury concierge We are building a unified, high-touch operational platform for an ultra-luxury concierge business, replacing a legacy tool sprawl with an enterprise-grade ecosystem. The system runs on a Modular Monolith architecture powered by a NestJS (TypeScript) backend on AWS, servicing three primary user interfaces: an intensive Back Office Admin Panel (ReactJS), a Member Web App (ReactJS), and Member Mobile Apps (React Native).
The platform integrates complex asynchronous communication pipelines (Email, SMS, WhatsApp), AI-assisted operations, spatial/vector databases, and strict security and role-based access controls
Requirements
- 5+ years of professional software engineering experience with TypeScript end-to-end across backend and frontend environments.
- Backend Mastery: Strong production experience with NestJS (Modules, Guards, Interceptors, Pipes) and Node.js.
- Frontend Mastery: Deep experience with ReactJS (hooks, state management, modern UI patterns) and React Native (iOS & Android).
- PostgreSQL Expertise: Proven experience with relational database design, complex SQL queries, migrations, and ORMs (Prisma or TypeORM).
- Advanced AI Usage & Vector Search: Proven experience working with LLM APIs / Providers (AWS Bedrock, OpenAI, Anthropic Claude), vector search databases (pgvector, Pinecone, or Qdrant), and RAG architecture.
- AWS & Infrastructure: Hands-on experience with managed AWS services (ECS Fargate, S3, Cognito, EventBridge, SQS, KMS, Secrets Manager).
- State & Data Fetching: Proficiency with asynchronous data fetching libraries (e.g., TanStack Query / React Query), REST APIs, and typed API client generation.
- Authentication & RBAC: Experience implementing multi-tenant auth workflows (OAuth2, JWTs, SSO federation) and strict permission matrices.
