The future of software development is autonomous. AWS is building Kiro Autonomous Agent —a frontier agent that independently tackles development tasks, maintains context across interactions, and continuously learns from its work. This isn't just another AI tool; it's a fundamental shift in how software gets built and maintained.

We're looking for engineers who want to shape this transformation. You'll work alongside exceptional talent solving novel problems at the intersection of AI and software engineering. The challenges are unique: building systems that operate autonomously, retain context across complex workflows, and improve through experience—all while meeting AWS's exacting standards for scale, reliability, and security.

Your impact will be immediate and visible. You'll ship features that directly improve how developers work. Daily collaboration includes code reviews, mentorship in both directions, and rapid skill development. From day one, you'll have opportunities to lead—whether that's owning projects, defining technical direction, or shaping how the team operates.

This is your chance to build the agent that builds the future.

Key job responsibilities
You'll shape the technical direction and architecture of Kiro Autonomous Agent service. Working directly with customers, you'll uncover real-world development challenges and translate them into product capabilities—staying true to Amazon's customer-obsessed approach. You'll build and operate production systems using industry-leading CI/CD practices, ensuring Kiro Autonomous Agent maintains the reliability and performance our customers depend on.

Your responsibilities span the full lifecycle: from architectural decisions that define how an autonomous agent learns and maintains context, to hands-on development of features that transform how software gets built. You'll balance innovation with operational excellence, making technical choices that enable Kiro to work independently while meeting AWS's standards for scale and security.

Your responsibilities span the full lifecycle: from compiler technologies to agent training and steering to scalable deployment. You'll balance innovation with operational excellence, making technical choices that enable Kiro agents to work smoothly for a wide class of developers while meeting AWS's standards for scale and security.
