AI Engineer — AWS Bedrock AgentCore & Production Agentic Systems | LATAM & Europe

Headquarters: Remote
URL: https://www.toptal.com/

About the Role

We're looking for engineers to help build and productionize AI systems on AWS Bedrock AgentCore — real conversational AI, RAG pipelines, and agent architectures that go well beyond proof-of-concept and serve live traffic and real users. Whether your strength is on the AI application side (agents, RAG, orchestration) or the platform side (deployment, observability, security), this role sits at the center of turning working demos into production-grade, reliable systems on Bedrock's agentic stack. If you've built and shipped on AgentCore specifically — not just Bedrock in general — and want your work to run in production rather than sit in a notebook, this is built for that.

What You'll Do

• Design, build, and deploy conversational AI systems, chatbots, and AI agents using AWS Bedrock AgentCore

• Architect and ship production-grade RAG (Retrieval-Augmented Generation) systems — not prototypes, but systems serving live traffic

• Build and deploy LLM applications primarily on AWS Bedrock and AgentCore, with Azure OpenAI or equivalent platforms as secondary context

• Develop and orchestrate agent architectures within AgentCore, using frameworks such as LangChain, LangGraph, or LlamaIndex where applicable

• Build and maintain MCP (Model Context Protocol) server integrations to extend AgentCore agent capabilities

• Design and build the production service layer around AgentCore (Lambda, API Gateway, IAM, DynamoDB, OpenSearch, or equivalents)

• Establish CI/CD pipelines and manage development, beta, and production environments for AgentCore-based services

• Implement observability for AgentCore agents: tracing, dashboards, per-turn cost and latency metrics, error rates, and audit trails

• Implement key security controls — data-leakage protection, session isolation, auth/authz boundaries, secure prompt/response storage

• Write clean, maintainable, production-quality Python across the AI application and platform stack

• Monitor, evaluate, and iterate on agent, RAG, and platform performance in production

• Stay current with fast-moving developments in Bedrock, AgentCore, and agentic AI systems, and bring relevant advances into the project

What You Bring

• Proven, hands-on experience building and deploying AI agents on AWS Bedrock AgentCore in a production environment — not personal projects or tutorials

• Direct experience with AWS Bedrock's agentic tooling (AgentCore, Bedrock Agents, or equivalent Bedrock-native orchestration)

• Strong Python skills for AI application development and/or service integration

• Working experience with AWS cloud environments; Azure experience is a plus but not the primary requirement

• Experience with at least one of: agent orchestration frameworks (LangChain, LangGraph, LlamaIndex), RAG system design, or AWS production infrastructure (Lambda, API Gateway, IAM, DynamoDB, OpenSearch)

• Experience with observability and monitoring for AI or distributed systems

• Strong understanding of security, data handling, and production-readiness tradeoffs

• Comfortable working in a fast-moving, evolving technical environment with pragmatic engineering judgment

Nice to Have

• Experience with MCP servers

• Experience with infrastructure-as-code (CDK, CloudFormation) and CI/CD pipeline design

• Experience with distributed data tools such as Apache Spark, PySpark, or AWS EMR

• Experience with Amazon SageMaker or similar ML platforms

• Experience with OpenSearch vector search administration for RAG workloads

• Experience building data pipelines for AI evaluation and KPI extraction

• Experience with Azure OpenAI or other non-AWS LLM platforms

• Comfort working in an AI-assisted development environment using AI build and review tools
