Description: Overview: We are seeking a passionate and skilled AI Engineer with strong Node.js expertise and a proven track record in integrating modern AI tools and frameworks. You will play a critical role in building intelligent applications and backend services that leverage state-of-the-art large language models (LLMs), embeddings, and AI pipelines. Key Responsibilities: • Design and implement scalable AI-powered solutions using Node.js and modern AI tooling (e.g., LangChain, LlamaIndex, OpenAI, Hugging Face, etc.) • Build and maintain APIs and services to integrate LLMs, embeddings, vector databases, and inference engines into production systems • Collaborate with data scientists, MLOps engineers, and frontend teams to operationalize AI workflows — from prompt engineering to model output consumption • Develop backend pipelines for data preprocessing, chunking, retrieval-augmented generation (RAG), and prompt orchestration • Implement semantic search and intelligent assistants using Node.js and vector stores (e.g., Pinecone, FAISS, Chroma) • Stay up-to-date with emerging trends in LLMs, generative AI, and open-source frameworks; proactively recommend and evaluate tools • Ensure robustness, performance, and security of AI integrations and APIs • Conduct peer code reviews and support junior developers in learning modern AI stacks Qualifications: • Strong proficiency in Node.js, including experience with Express.js, REST APIs, and microservices • Solid understanding of AI/ML workflows, including prompt engineering, embeddings, model invocation, and response handling • Hands-on experience integrating OpenAI, Hugging Face, LangChain, LlamaIndex, or similar tools into real-world applications • Familiarity with vector databases (e.g., Pinecone, Weaviate, Chroma, FAISS) and semantic search architectures • Experience with cloud platforms (AWS, Azure, or GCP) and infrastructure tools like Docker and Kubernetes • Good grasp of SQL/NoSQL databases, asynchronous workflows, and CI/CD practices • Strong analytical, debugging, and communication skills Bonus Points For: • Experience building LLM-based chatbots, copilots, or agent frameworks • Knowledge of frontend frameworks (React.js/Next.js), GraphQL, or WebSockets
