Job :  | Amazon Web Services, Inc.

Build the systems that make AI agents secure, governed, and trustworthy  AWS SMGS‑Galaxi team builds intelligent, AI‑powered services that help thousands of internal users discover, secure, and govern information assets across AWS. The platform serves as a central nervous system for data intelligence, connecting teams with the assets they need while ensuring security, compliance, and operational efficiency at enterprise scale.

• Build secure, scalable distributed systems on AWS (Lambda, Neptune, DynamoDB, API Gateway, S3, Step Functions) via CDK.
• Develop multi‑agent AI systems using Bedrock Agents, MCP, knowledge graphs, vector embeddings, and RAG.
• Implement zero‑trust access control—IAM role chaining, ABAC, tenant isolation, and least‑privilege agent‑to‑service auth.
• Build MCP servers (Type Script/Python) with authorization boundaries, audit logging, and data classification enforcement.
• Architect observability for AI agents—invocation auditing, access pattern analysis, and lineage tracking.
• Drive operational excellence through threat modeling, security scanning, monitoring, and incident response.
• Collaborate across teams on system design, code reviews, and technical strategy.

Every day brings a different challenge. You might be designing an API in the morning, debugging a distributed system in the afternoon, and reviewing a teammate’s design by end of day. You’ll partner with engineers across AWS to solve complex, ambiguous problems spanning customer‑facing features, system performance, and cross‑team integrations. We look for curious, pragmatic builders with a bias for action and give you real ownership from day one to grow your technical depth, influence, and leadership over time.
