- LLM Techniques: Retrieval-Augmented Generation (RAG), Supervised Fine-Tuning (SFT), Parameter-Efficient Fine-Tuning (LoRA/QLoRA/PEFT), Reinforcement Learning from Human Feedback (RLHF), prompt engineering, and evaluation.
- Chatbots & Agents: Designing multi-turn conversational flows, tool invocation, agent routing/orchestration with LangChain, LangGraph, LlamaIndex, or similar.
- Vector Databases: Experience with FAISS, Milvus /Chroma / Pinecone / pgvector / S3 vector (indexing, similarity search, hybrid search).
- MCP Servers: Building and integrating Model Context Protocol (MCP) servers to securely expose domain tools/functions to LLMs.

- Soft Skills: Ownership mindset, rapid prototyping, clear technical writing; English at Upper-Intermediate (B2) or higher.
Key Responsibilities:
- Design & build end-to-end LLM workflows in Python โ from data ingestion to inference APIs;
- Implement RAG pipelines: document parsing, embedding generation, vector search, and evaluation;
- Create chatbots / autonomous agents with frameworks such as LangChain, LangGraph, LlamaIndex, Semantic Kernel, or CrewAI;
- Expose tools via MCP servers so that external LLMs can invoke domain-specific actions;
- Integrate no-/low-code automation (n8n, Make, Zapier) to orchestrate business workflows;
Write clean, test-driven code; set up CI/CD; monitor, log, and continuously improve model performance and system reliability.
Nice to Have:

- Hands-on experience with TensorFlow, PyTorch, NumPy, Pandas; ability to train, fine-tune, and evaluate ML/LLM models.
- Familiarity with front-end stacks (React/Next.js, TypeScript) for building AI-powered user interfaces;
- Bonus: Experience in Generative Graphics, including Stable Diffusion, Inpainting techniques, and ControlNets;
- Bonus: Experience in LLM hosting and working with llama.cpp.
