Job Technologies
Your role in the team
- We are developing an exclusive, subscription-based AI product that provides paying members with conversational access to the documented principles of a well-known personality.
- This is not a generic chatbot, but a precise Retrieval-Augmented Generation (RAG) system that is based solely on the verified content of our client.
- RAG Pipeline & AI: Architecture and development of the server-side RAG pipeline, from query processing through embedding and vector search to prompt construction.
- Full-Stack Development: Building the frontend and backend, ensuring that all LLM API calls remain strictly server-side.
- Subscription & Payments: Integration of a three-tier subscription model including a 7-day trial via Stripe.
- You implement robust webhook logic for animal validation directly in the database.
- Automation (Data Ingestion): Building a pipeline (e.g., via or n8n) that automatically transcribes new audio and video content (Whisper API), cleans, chunks, and loads it into the vector database.
- Data Intelligence: Development of an internal Behavioral Analytics Dashboard that tracks search queries, emotional tone, content gaps, and limit breaches in real-time.

Our expectations of you
Qualifications
- Practical knowledge in building RAG systems, managing vector databases (Pinecone or Weaviate), and working with LLM APIs (especially Anthropic Claude Sonnet and OpenAI).
- Proficient in PostgreSQL (e.g., via Supabase) and authentication solutions such as Clerk or Supabase Auth.
- High security awareness: API keys and rate limits must be processed and enforced server-side.
- The ability to work independently within a tight 12-week schedule (Build-to-Launch) and proactively coordinate technical decisions with our Project Lead.
Experience
- Extensive experience in developing modern full-stack web applications, ideally with our preferred tech stack: Next.js (React) for the frontend and Node.js (Express or Next.js API Routes) for the backend.
- Experience with secure implementation of Stripe (subscriptions, dunning, webhooks).
