Are you passionate about building software systems that operate at massive scale and directly impact millions of customers? We're looking for a Software Development Engineer III to join our team at Amazon, where you'll lead the design and delivery of complex software solutions across the full development lifecycle. In this role, you'll tackle problems where the technology strategy isn't yet defined, working backwards from customer needs to architect systems that are scalable, performant, and secure. You'll balance competing constraints, drive technical direction, and collaborate with engineers across multiple teams to deliver meaningful results. If you're a builder who thrives on turning ambiguity into elegant, well-crafted solutions, we'd love to hear from you. Key job responsibilities - Lead the end-to-end design, implementation, and delivery of software systems spanning multiple features, from defining technical strategy through deployment and ongoing maintenance. - Own your team's architectural direction, making informed trade-offs between short-term delivery needs and long-term extensibility, performance, and security. - Collaborate with engineers, product managers, and cross-functional partners to clarify requirements, build consensus on technical approaches, and ensure successful integration across dependent systems. - Drive adoption of engineering best practices on your team, including code quality, operational excellence, and effective use of generative AI tools to augment productivity and software quality. - Coach and mentor engineers on your team and across related teams, providing guidance on system design, coding practices, and career development. A day in the life You'll start your day reviewing design documents and code reviews, providing feedback that raises the quality bar for your team. Throughout the day, you'll move between deep technical work—writing code, prototyping solutions, and debugging complex issues—and collaborative sessions where you align with partner teams on system interfaces and integration points. You'll also spend time identifying opportunities to simplify existing systems and proactively addressing architectural gaps before they become problems. About the team Our team is focused on building software that customers rely on every day. We value collaboration, technical rigor, and a pragmatic approach to solving hard problems. You'll work alongside talented engineers who are committed to learning from each other and pushing the boundaries of what's possible at Amazon's scale. We're investing in new capabilities and looking for someone who will help shape our technical vision for the years ahead. About AWS Diverse Experiences AWS values diverse experiences.
