Software Development Engineer II, EBS ECAS

Are you excited about building software that impacts millions of customers? Do you enjoy solving complex technical problems while collaborating with a talented team of engineers? We're looking for a Software Development Engineer II to join Amazon and help design, build, and operate systems that matter at scale. In this role, you will contribute across the full software development lifecycle—from understanding customer needs and defining solutions to implementing, testing, deploying, and operating production software. You will tackle challenging problems where the business context is clear but the path forward requires creative, well-reasoned design. You will write high-quality, maintainable code and help raise the bar for your team through mentorship and thoughtful code reviews. If you are a self-starter who thrives on turning ambiguity into clarity and delivering meaningful results, we'd love to hear from you. Key job responsibilities - Design and implement software solutions for major features and improvements, applying sound system design principles that account for scalability, maintainability, and performance. - Write clean, well-tested, and maintainable code using optimal data structures and algorithms, and actively participate in code reviews to provide constructive feedback to teammates. - Collaborate with customers, stakeholders, and cross-functional peers to understand business requirements and deliver solutions that balance customer needs with technical considerations. - Identify and resolve root causes of operational issues, driving permanent fixes and continuously improving your team's operational health and processes. - Mentor and coach fellow engineers, train new team members on system architecture and operations, and contribute to clear technical documentation that supports long-term team knowledge. A day in the life Your day begins by reviewing operational metrics and addressing any alerts from the systems you own. You then join your team's standup to align on priorities before diving into design or implementation work. You might spend the morning writing code for a new feature, then shift to reviewing a teammate's pull request in the afternoon—offering feedback that helps them grow. You regularly collaborate with product and engineering partners to refine requirements, and you evaluate opportunities to integrate generative AI tools where they can improve productivity. About the team Our team is focused on building reliable, scalable software that directly improves the customer experience at Amazon. We value collaboration, continuous learning, and a commitment to operational excellence. Every engineer on the team has the opportunity to influence technical direction and contribute to meaningful projects. We are building for the long term, investing in systems that are extensible and well-documented so they can evolve as customer needs change. If you're looking for an inclusive environment where your ideas are heard and your growth is supported, this is the team for you.
