Job Description

We’re hiring an AI Developer to help us build and scale production-grade AI agents. This role focuses on agentic systems that use RAG, vector databases, and structured tool use to deliver reliable outcomes. You’ll work end-to-end—from architecture to deployment—on AI systems that go well beyond prompt experiments.

What You’ll Do

  • Build and maintain AI agents capable of reasoning, planning, and executing tasks
  • Design and implement Retrieval-Augmented Generation (RAG) pipelines
  • Apply effective data chunking, embedding, and retrieval strategies
  • Integrate vector databases into agent workflows
  • Use and extend AI agent frameworks (LangChain, LlamaIndex, AutoGen, CrewAI, etc.)
  • Connect agents to APIs, internal systems, and external tools
  • Optimize prompts, agent logic, and memory for reliability and performance
  • Deploy, monitor, and iterate on AI systems in production
  • Collaborate closely with product and engineering teams

  • Strong proficiency in Python and/or JavaScript/TypeScript
  • Hands-on experience building AI agents or LLM-powered applications
  • Practical experience with RAG architectures
  • Solid understanding of vector databases (e.g., Pinecone, Weaviate, FAISS, Chroma)
  • Experience with data chunking, embeddings, and retrieval tuning
  • Familiarity with AI agent frameworks such as LangChain, LlamaIndex, AutoGen, or similar
  • Experience integrating LLMs with tools, APIs, and structured data
  • Ability to reason about and debug agent behavior in real-world scenarios

Nice to Have

  • Experience with multi-agent systems
  • Production deployment experience on AWS, GCP, or Azure
  • Familiarity with LLM evaluation, monitoring, and observability
  • Background in backend engineering or distributed systems
  • Experience working in startup or fast-paced product environments

What Success Looks Like

  • You ship reliable, production-ready agents
  • RAG systems you build retrieve relevant, high-quality context
  • Agents behave predictably and improve over time
  • You proactively identify and fix failure modes
  • You balance speed with system robustness
