Our systems process millions of packages a day and ensure that Amazon can meet the customer delivery promise. Our mission is to build the most efficient and optimal transportation system on the planet using our engineering muscle as our biggest advantage.
You will help define the system architecture, own and implement specific components, and help shape the overall customer experience. You’ll collaborate closely with research scientists, UX researchers and designers, and other engineering team members to help define the product. As an experienced engineer and early team member, you will provide the technical experience to the team, drive best practices, mentor other engineers and drive continuous improvements in engineering and operational excellence.

This role offers wide scope, autonomy, and ownership. You will be counted on to be an influential voice in decisions related to system architecture, feature development, and product strategy. We have an ambitious mission requiring engineers with great judgment and experience in building great customer experiences. The ideal candidate should have deep end-to-end front-end application knowledge, an obsession to build the right products for our customers, and experience with high-performance, highly available web applications. The candidate should be willing to take on challenging initiatives and be capable of working both independently and with others as a team.

In this role you will:
