Software Development Engineer, Kiro

The future of software development is autonomous. AWS is building Kiro - a frontier developer tool 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, feel fast and natural to use, integrate cleanly with the tools and workflows developers already rely on, and meet 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.Live in the terminal? If you've built command-line or terminal-based tools and care deeply about user-experience, shell, responsiveness, and cross-platform behavior, this is the perfect opportunity for you.This is your chance to build the agent that builds the future.Key job responsibilitiesYou'll shape the technical direction and architecture of Kiro. 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 maintains the reliability and performance our customers depend on.Your responsibilities span the full lifecycle: from architectural decisions that define how an agent manages sessions, state, and context, to hands-on development of features that transform how software gets built. You'll care deeply about responsiveness, ergonomics, and cross-platform behavior - the details that make a developer tool feel great to use - while balancing innovation with operational excellence and AWS's standards for scale and security.About the teamDiverse ExperiencesAWS values diverse experiences.
