Principal AI Engineer (LLM Agents & Orchestration)
ImagineArt•Fan Francisco, CA
•Onsite
About The Position
We are looking for a deep expert in Large Language Models (LLMs) to lead the architectural development of our new "Super Agent" within Chatly. You will move beyond simple chat interfaces to build autonomous agents capable of complex reasoning, tool usage, and seamless integration with external workflows.
Requirements
- Deep proficiency in Python (or TypeScript) and the modern AI stack (LangChain, LlamaIndex, DSPy)
- Strong grasp of how to leverage specific model strengths (e.g., GPT-4o for reasoning, Haiku/Flash for speed) and experience with Function Calling/Tool Use
- Hands-on experience with vector databases (Pinecone, Milvus, Weaviate) and embedding strategies
- Experience designing event-driven architectures where agents respond to triggers, not just user prompts
Responsibilities
- Design and implement stateful agentic workflows (using frameworks like LangGraph or custom Python/TypeScript solutions) that can plan, execute, and self-correct
- Build the "hands" of the agent. Develop robust integration layers that allow the LLM to interact with our internal APIs, databases, and third-party tools reliably
- Optimize inference pipelines for speed (streaming, token optimization) and reliability (handling hallucinations, structured output validation)
- Architect advanced RAG (Retrieval-Augmented Generation) systems to give the Super Agent persistent memory and context awareness across sessions
- Establish a rigorous testing framework for non-deterministic model outputs to ensure the agent behaves as expected in production
Benefits
- Competitive compensation and benefits
- A culture where learning, growth, and experimenting with new ideas are deeply encouraged
