Main Responsibilities:

• Architect and implement AI-first features in our prompt-to-design AI tool and ChatBot ecosystem.

• Build, customize, and deploy intelligent agents using LLMs (e.g., OpenAI, Anthropic) and LangGraph.

• Integrate and manage vector databases like Pinecone, Weaviate, or Chroma for memory, semantic search, and retrieval-augmented generation (RAG).

• Engineer multi-step workflows and decision logic across agents for dynamic, adaptive responses.

• Fine-tune models or optimize prompts to align with domain-specific use cases.

• Own backend AI service architecture with a focus on Node.js, scalability, and efficiency.

• Integrate with third-party APIs and AI platforms to augment our AI capabilities.

• Collaborate with front-end engineers and product designers to ensure seamless user experiences.

Key Requirements:

• at least 2 years focused on AI/LLM applications.

• Experience with Node.js.

• Proficient in LangChain, LangGraph, or related agent orchestration frameworks.

• Hands-on with vector databases (e.g., Pinecone, Weaviate, Chroma) and semantic search techniques.

• Experience deploying AI agents in production.

• Strong understanding of prompt engineering, fine-tuning, API integrations, and retrieval pipelines.

Nice to Have:

• Familiarity with cloud platforms

• Familiarity with front-end frameworks (React, Next.js)

• Exposure to tools like OpenAI Assistants API, Anthropic Claude, or Google Gemini.
