About The Position

We are looking for a Principal Software Engineer to define the future of agent
orchestration at Kiro. Working on Kiro Web (kiro.dev), you'll lead the evolution
from a single-product interface into a comprehensive agent orchestration
platform. You'll solve fundamental challenges that currently limit orchestration
to senior+ engineers: making agent swarms visible and debuggable, managing
context at scale, and balancing control with autonomy.
You will work with an exceptional team including internal Kiro SMEs like Al
Harris to solve hard problems and learn new skills. Our research with internal
and external power users who've achieved 10x productivity gains through agent
orchestration gives us a unique advantage—you'll embed proven practices into
Kiro's architecture. In addition to the technical challenges of agent
orchestration, you'll learn how to build a service that meets AWS's high bar for
availability, scalability, and security.
You'll have a direct line to our customers' experience and a direct means to
improving it. On a daily basis, you'll work with teammates to review each
other's code, mentor and be mentored. You'll have an opportunity to lead from
day one—from leading the agent orchestration architecture, to driving technical
processes, to selecting frameworks and patterns, to teaching and learning from
your teammates.

AI is transforming software development, and agent orchestration represents the
next frontier. As AI agents proliferate across the industry, the critical
challenge is no longer building individual agents—it's orchestrating them
effectively. AWS is at the forefront of this transformation, and we're building
the technical foundation that will make sophisticated multi-agent workflows
accessible to developers worldwide.

• Background in building observability, debugging, or monitoring systems for complex distributed workflows
• Track record of solving intrinsically hard problems in areas like context management, state coordination, or autonomous system control
• Experience working with user research to inform technical architecture decisions
• Contributions to open-source projects in agent frameworks, orchestration tools, or developer platforms
• Experience scaling platforms from individual users to team and enterprise deployments
