Original job description

How would you like to impact hundreds of millions of customers around the world and empower hundreds of engineers daily? Mobile Shopping is one of the fastest growing strategic businesses within Amazon. Our team owns how the Amazon shopping apps perform on Android and iOS. We make sure they start fast, respond instantly, and stay smooth as hundreds of teams add new features.

Do you want to solve complex problems at the scale of the Amazon Mobile Shopping app? Do you want to build the tools that measure, optimize, and safeguard app startup, latency, and runtime performance? Do you want to explore how AI can detect, diagnose, and resolve performance issues before customers notice? Do you want to work with talented, tenured engineers who help each other grow? Then we would like to hear from you!

Key job responsibilities

Design, implement, and support robust and stable solutions across Amazon's mobile shopping apps
Profile and optimize app startup, latency, and runtime performance across critical customer code paths
Build the systems and tooling that automatically catch performance regressions before they reach millions of mobile Shoppers
Develop systems that support AI-assisted mobile development at scale, exploring approaches like automated anomaly detection and root-cause diagnosis
Partner with dozens of teams across Amazon to improve performance-critical code paths and remove bottlenecks
Help raise the bar for mobile development as we change the way we develop mobile apps

About the team Our team owns app performance for the Amazon Shopping apps on iOS and Android. Every startup, tap, and scroll that millions of customers experience runs through the systems we build. We measure how the apps perform, optimize the paths that matter most, and build the tooling that keeps performance from regressing as hundreds of teams ship new features.

We are a group of engineers who like hard problems, help each other grow, and take pride in work that hundreds of teams and millions of customers depend on daily. Basic qualifications

3+ years of non-internship professional software development experience
2+ years of non-internship design or architecture (design patterns, reliability and scaling) of new and existing systems experience
