Job Summary

We are seeking a highly skilled AI/ML Software Engineer with hands-on experience in designing and deploying end-to-end LLM-powered systems, RAG pipelines, and agentic AI architectures. The ideal candidate combines strong Python development skills with advanced understanding of Large Language Models, LangChain, vector databases, prompt optimization, and multi-agent orchestration frameworks. ‍

Key Responsibilities

• Design, develop, and deploy RAG (Retrieval-Augmented Generation) systems integrating vector databases, embedding models, and custom retrievers.
• Architect and fine-tune custom LLMs (via parameter-efficient tuning, LoRA, or domain-specific training).
• Create and manage agentic AI workflows—multi-step reasoning systems powered by tools such as LangChain, CrewAI, or OpenDevin.
• Implement prompt engineering and prompt-chaining techniques to optimize LLM behavior and reliability.
• Build and maintain scalable LangChain-based applications that interact with databases, APIs, and business systems.
• Collaborate with data scientists to design and deploy ML/AI pipelines leveraging AWS, Azure, or GCP cloud infrastructure.
• Develop, test, and optimize APIs that integrate AI reasoning and autonomous decision-making capabilities.
• Monitor and improve model performance, latency, and token efficiency using observability tools like LangFuse, Phoenix, or OpenDevin dashboards.
• Document architectural decisions, experiment metrics, and system flows for technical transparency. ‍

Required Skills and Experience

• 4+ years in Python software development, with strong understanding of asynchronous programming and API design.
• Solid experience deploying LLM applications using frameworks like LangChain, LlamaIndex, or Haystack.
• Proficiency working with vector databases (FAISS, Pinecone, Weaviate, Milvus, Qdrant) and embedding models (OpenAI, sentence-transformers, Cohere, HuggingFace).
• Experience designing autonomous agent systems, connecting LLMs with Python functions, tools, or APIs.
• Strong command of prompt engineering, including contextual grounding, role prompting, and few-shot exa…
