Software Engineer Internal Tools Jobs in Kent, WA

Are you passionate about leveraging GenAI to simplify the builder experience and accelerate innovation at Amazon scale?
The GenAI Tools & Agentic Ecosystem team is on a mission to make AI agents a natural extension of every Amazon builder's workflow. We build the platforms that let teams create, publish, and discover AI skills and tool integrations - and we enable autonomous agents to tap into Amazon's vast internal ecosystem on behalf of builders. We are part of Amazon Software Builder Experience (ASBX), the organization that provides the tools and platforms every Amazon engineer uses to build, test, deploy, and operate software.
This is a rare opportunity to shape how thousands of engineers work with AI. As an SDE II, you will build the infrastructure layer that connects generative AI to the daily work of Amazon builders - from the APIs agents call, to the platforms teams use to ship new AI capabilities company-wide. If you want your code to multiply the productivity of thousands of engineers, this is the role.
Key job responsibilities
Design and build scalable platform services for distributing AI skills, agents, and tool integrations to builders across Amazon
Develop APIs and infrastructure that enable autonomous agents to securely access internal resources and systems
Build benchmarking and prompt trace analysis systems that measure agent quality, identify regressions, and drive continuous improvement of AI capabilities
Partner with teams across Amazon and AWS to onboard new AI capabilities and drive adoption across the builder ecosystem
Deliver iterative improvements to production systems while driving long-term platform evolution
About the team
The GenAI Tools team operates at the center of Amazon's AI agent ecosystem. Every decision we make - what tools agents can access, how capabilities are distributed, what quality bar is enforced - ripples across hundreds of thousands of builder sessions weekly. We enable tools like Kiro, Claude Code, Codex and autonomous agents to accelerate developer workflows at a scale that is unmatched outside Amazon.
