The Role
As a Lead Engineer, you will be our technical authority on Agentic AI. You will design and deploy sophisticated multi-agent systems, proving concepts through rapid prototyping and scaling them into production-grade solutions.
Key Responsibilities:
- Agentic AI Engineering: Develop multi-agent systems using frameworks like LangGraph or CrewAI for autonomous research and automated coding.
- Advanced RAG & Memory: Build sophisticated Retrieval-Augmented Generation (RAG) pipelines and long-term model memory.
- Model Optimization: Fine-tune open-source models (e.g., Llama 3/4) to reduce latency and operational costs.
- LLMOps: Implement automated "Evals" to measure hallucination rates and tool-calling accuracy.
- Technical Leadership: Architect scalable, secure applications and advocate for best practices in automation and continuous integration.
What We’re Looking For
- Expert Python & TypeScript: Deep proficiency in Python for production AI and strong technical fluency in TypeScript.
- AI Frameworks: Hands-on experience with some of the following: LangChain/LangGraph, LlamaIndex, PyTorch, and FastAPI.
- Modern Infrastructure: Experience with AWS Bedrock/SageMaker and using Docker/Kubernetes to scale agent instances.
- RAG Expertise: Proven experience building RAG systems; experience with Graph-RAG (e.g., Neo4j) is a major plus.
- Production Pedigree: Demonstrable experience owning the design and delivery of complex AI systems in live customer environments.
