Sr. Software Dev Engineer, Kiro

Job description

The future of software development is agentic. AWS is building Kiro — a frontier AI coding agent that tackles development tasks end-to-end, retains context across complex workflows, and continuously learns from its work. Kiro is already transforming how developers build and maintain software, and we're just getting started. 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: orchestrating AI workflows across dozens of models, building context systems that make every interaction smarter than the last, and scaling it all to meet AWS's exacting standards for reliability and security. Your impact will be immediate and visible. You'll ship features that directly improve how developers work — from launching new models in hours, to building intelligent routing, to designing the context layer that makes Kiro genuinely understand your project. These aren't incremental improvements; they're the building blocks of a new category of developer tool. From day one, you'll have opportunities to lead — whether that's owning a critical system, defining technical direction for a new capability, or shaping how the team operates. You'll work across distributed systems, real-time streaming, multi-model orchestration,…
