If you have ever recommended a product on Amazon to someone, chances are you used the "Share" feature! The Social Share team drives programs and software initiatives to ensure Amazon customers get the best sharing experience. Shopping is inherently social and we aim to help our customers connect with their friends and family more conveniently as they shop on Amazon.
As an SDE in our team, you will have the opportunity to own customer-facing experiences and truly innovate on their behalf. You will help to define, prototype, build, and maintain these experiences that empower the customer shopping journey on Amazon. You will collaborate with UX designers, product managers, and your team to build stable, secure, and world-class cross-platform products that makes sharing easy and fun for customers.

Successful candidates need to be innovative, flexible, self-directed, able to design and write reliable, maintainable and high-performance code. You must be able to deal with ambiguity, and make data-driven decisions. If you enjoy working in a dynamic environment and like the idea of working autonomously, this is the career opportunity for you.

We care about your career growth. Our team is dedicated to supporting new team members. Our team has a broad mix of experience levels and Amazon tenures, and we're building an environment that celebrates knowledge sharing and mentorship. You will have ample opportunities to grow your skills in several areas not limited to front-end engineering.
