Sr. Software Dev Engineer, Kiro

Amazon • Seattle, WA

About The Position

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.

Agentic AI drives innovation at the forefront of artificial intelligence,
enabling customers to transform their businesses through cutting-edge AI
solutions. We build and deliver the foundational AI services that power the
future of cloud computing, helping organizations harness the potential of AI to
solve their most complex challenges. Join our dynamic team of AI/ML
practitioners, applied scientists, software engineers, and solution architects
who work backwards from customer needs to create groundbreaking technologies. If
you're passionate about shaping the future of AI while making a meaningful
impact for customers worldwide, we want to hear from you.
