LLM and Backend Development
  • Build the LLM-based backend logic (FastAPI preferred).
  • Implement retrieval-augmented generation (RAG) to fetch structured and unstructured data from OXRED.
  • Use frameworks like LangChain, LlamaIndex, or Haystack to manage context retrieval, query routing, and summarization.
  • Develop prompt templates, intent classifiers, and structured query generators.
Integration and Testing
  • Integrate the chatbot logic with the existing OXRED AskOX frontend.
  • Define and test different query types (e.g., fleet-level summaries, vehicle-level drilldowns, performance metrics).
  • Ensure secure and efficient data flow between OXRED APIs and the AskOX backend.
Optimization and Reporting
  • Evaluate and improve retrieval accuracy, latency, and hallucination rates.
  • Implement caching or schema-based memory for frequently accessed data.
  • Provide sample test cases and response evaluation reports.
Documentation and Handoff
  • Deliver modular, production-ready code and API documentation.
  • Include retraining or model-upgrade guidelines.
  • Provide sample conversation flows and schema mappings.

Requirements:

  • Strong experience with LLMs, LangChain, or LlamaIndex.
  • Proficiency in Python and FastAPI.
  • Experience with retrieval pipelines, SQL, or CrateDB/PostgreSQL.
  • Understanding of vector databases (e.g., FAISS, Chroma, Pinecone).
  • Ability to design efficient, prompt, and retrieval logic for structured data queries.
  • Knowledge in the EV Domain (brownie points).

Preferred Qualifications:

  • Knowledge of EV analytics, fleet management, or IoT data.
  • Familiarity with OpenAI, Anthropic, or Ollama models.
  • Experience with embedding optimization and hallucination control.
  • Prior exposure to multi-agent or AI orchestration frameworks.
