The engineer will be responsible for delivering prototypes, MVPs, and production-ready services that integrate generative models, agents, and light data-preparation flows while maintaining high standards in quality, security, performance, and UX.🔧 Key ResponsibilitiesAI Applied (Core of the Role) Design and implement well-structured RAG pipelines (chunking, embeddings, retrieval optimization). Build and orchestrate AI agents using LangGraph, CrewAI, or Strands Agents. Implement security workflows: PII sanitization, guardrails, safety layers, model validations. Integrate generative models through AWS Bedrock, Claude, Amazon Q, OpenAI, or HuggingFace. Backend Develop APIs and serverless microservices in Node.js or Python. Implement business logic, authentication, authorization, and model/service integrations. Perform only the necessary data preparation for AI workloads (e.g., text cleaning, normalization, embedding generation, vector data loading). Manage vector databases at a practical level: Pinecone, Chroma, Qdrant, OpenSearch. Frontend & User Experience Build functional interfaces using React / Next.js, leveraging AI-generated components. Create lightweight dashboards or visual tools for agents, RAG flows, and internal applications. Rapidly prototype interfaces using Lovable, Figma Dev Mode, or similar tools. Cloud & DevOps Deploy solutions on AWS (Lambda, Amplify, API Gateway, S3, CloudFront, Bedrock). Configure monitoring, logging, and metrics to evaluate model behavior and agent performance. Automate unit, integration, and end-to-end tests using AI-assisted tools (Claude Code, Copilot)🧠 Core Technical Skills Deep understanding of RAG: chunking strategies, embeddings, retrieval patterns, evaluation. Vector Databases: Pinecone, Chroma, Qdrant, or OpenSearch. AI Agents: LangGraph, CrewAI, Strands Agents. Security & Guardrails: PII handling, safe prompting, compliance workflows.
