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.

This role is only open for LATAM candidates

Nice to Have
Hands-on AWS deployment experience (Bedrock, Lambda, ECS/Fargate).
Background working with U.S. or enterprise clients in fast-paced, high-stakes environments.
