Description

We are building Genesis Runtime, AWS's managed service for deploying, running, and scaling AI agents in production environments. You will design, implement, test, document, and support this enterprise-grade platform that enables customers to transform local agent prototypes into production-ready deployments in hours rather than months.

As a key member of our team, you'll develop critical components of our multi-modal infrastructure that supports real-time interactions with fast cold starts (200ms) and long-running asynchronous agents (up to 8 hours). You'll build systems that automatically scale from zero to hundreds of concurrent sessions without capacity planning, while ensuring enterprise-grade security through isolated execution
environments, identity propagation, and configurable guardrails.

You'll serve as a technical lead on complex projects implementing session and state management across frameworks like LangChain, LangGraph, CrewAI, and LlamaIndex. Your work will enable bi-directional streaming for text, images, audio, and video with unrestricted payload sizes, while maintaining strict security boundaries between user sessions. You'll collaborate with customers to understand their agent deployment challenges and translate those requirements into robust, scalable solutions that work seamlessly with any foundation model.

We're moving fast in this emerging space, and this is a great team to join if you want to have a huge impact on AWS and the world's customers we serve!

Here at AWS, we embrace our differences. We are committed to furthering our culture of inclusion. We have ten employee-led affinity groups, reaching 40,000 employees in over 190 chapters globally. We have innovative benefit offerings, and host annual and ongoing learning experiences, including our Conversations on Race and Ethnicity (CORE) and AmazeCon conferences.

Our team puts a high value on work-life balance. It isn't about how many hours you spend at home or at work; it's about the flow you establish that brings energy to both parts of your life. We believe striking the right balance between your personal and professional life is critical to life-long happiness and fulfillment. We offer flexibility in working hours and encourage you to find your own balance between your work and personal lives.
