About the role

This role involves designing and building production-grade applications powered by large language models (LLMs) and generative AI. The engineer will work on projects such as retrieval-augmented generation (RAG) systems, chatbots, and content generation tools. Responsibilities include developing prompts, retrieval pipelines, evaluation frameworks, integrating LLM APIs and open-source models, monitoring application quality and safety, and collaborating with product and engineering teams to deliver end-to-end solutions. The position requires strong Python skills, experience with LLM APIs and frameworks, and a background in building RAG systems. A degree in Computer Science, Engineering, or a related field is also required.

Must have

  • Strong Python and software engineering fundamentals
  • Hands-on experience with LLM APIs (OpenAI, Anthropic, Gemini or similar) and frameworks such as LangChain or LlamaIndex
  • Proven experience building RAG systems with embeddings and vector databases (Pinecone, pgvector, FAISS or similar)
  • Experience evaluating LLM outputs and reducing hallucinations
  • Experience with REST APIs, cloud deployment and Git
  • Degree in Computer Science, Engineering or a related field

Nice to have

  • Fine-tuning experience (LoRA, PEFT) with Hugging Face
  • Agent frameworks (LangGraph, CrewAI) and tool calling
  • Knowledge of LLM observability tools and prompt versioning
  • Experience with multimodal models
