Role Overview

We are seeking exceptional Principal Engineers to join the Agentic AI organization at AWS. This requisition represents multiple opportunities across various teams building the next generation of AI agent platforms, services, and tools. As AI agents proliferate across the industry, AWS is at the forefront of this transformation, building the technical foundation that will make sophisticated multi-agent workflows accessible to developers worldwide. In these roles, you'll design, build, and scale systems that genuinely move the needle for customers — leveraging the latest AI-powered development tools to work faster, think bigger, and ship better. We're looking for Principal Engineers who bring rare technical knowledge, a builder's instinct, and the kind of curiosity that doesn't stop at "good enough."

What You'll Do

As a Principal Engineer in Agentic AI, you will be a hands-on technical leader tackling the hardest, most ambiguous problems in the rapidly evolving Generative AI space. You will:


• Deliver high-impact technical projects and architect software systems built to scale — leveraging cutting-edge AI-powered development tools to push the boundaries of what's possible.
• Build trend-setting AWS services in the Gen AI field, solving the hardest engineering challenges to enable machine learning powered solutions for customers
• Deliver strategic technical projects that have significant bottom-line impact on our business and competitive position
• Design and architect large-scale systems that are scalable, efficient, and fault tolerant as tier zero Amazon services
• Provide technical leadership by mentoring engineers and drawing from deep technical expertise to guide complex technical decisions
• Shape technology, product, and business in a fast-moving, startup environment within a large company
• Work across domains including compute, databases, networking, identity, and ML science teams

Depending on your background and interests, you may work on:

• AgentCore Platform: Building comprehensive, modular infrastructure for deploying and operating autonomous AI agents securely and at scale, including serverless runtime, memory, identity, gateway, and observability components
• Agent Orchestration: Developing sophisticated multi-agent coordination and workflow orchestration patterns, solving intrinsically hard problems in context management, state coordination, and autonomous system control
• Knowledge & Evaluation: Creating robust evaluation frameworks, knowledge retrieval systems, and augmentation services that power AI-driven solutions with accurate, context-aware information
• Security & DevOps: Implementing Shift Left Security by building intelligent security agents that perform application security engineering and penetration testing functions, preventing insecure code from reaching production
• Migration & Modernization: Accelerating enterprise modernization through agentic AI services that transform .NET, mainframe, and VMware workloads
