About the Role

Join Yisrael Technology as a Senior AI Engineer and contribute to an agentic AI project for a U.S. based consulting and technology advisory client, building production-grade LLM applications with LangGraph, RAG pipelines, and AWS, working alongside software and data engineers, architects, and business stakeholders to build scalable, secure, and observable solutions.

What You'll Work On

- Design stateful single and multi-agent workflows in LangGraph, with conditional routing, branching, retries, checkpoints, recovery, human-in-the-loop approvals, and structured outputs.
- Build RAG pipelines that connect LLMs to the client's business systems, databases, and APIs, including ingestion, chunking, embeddings, and hybrid retrieval.
- Ship production Python services and FastAPI microservices with secure integrations and modular architecture.
- Create evaluation datasets and trace prompts, model calls, retrieval, and tool use for reliability and observability (LangSmith, Phoenix, OpenTelemetry, or CloudWatch).
- Deploy containerized AI workloads on AWS (Bedrock, Lambda, ECS/Fargate, API Gateway, SQS, EventBridge) with CI/CD in place.

Requirements





- 4+ years of professional experience in AI/ML engineering, ideally with a background as a Data Scientist or similar.
- Strong professional Python experience with hands-on delivery of LLM-powered or agentic AI applications.
- Solid LangGraph experience (LangChain familiarity is a plus): multi-step workflows, tool calling, retrieval, validation, routing.
- Comfortable with FastAPI, RAG, embeddings, vector search, and integrating with enterprise systems.
- Advanced English (C1/C2). You'll be working directly with the client.
- Ability to work an 8am–5pm EST overlap.
