Join the Customer Segmentation team and help build intelligent systems which understand customers better. We do this through a highly available, low-latency web api which in real-time evaluates membership in customer segments (customer groups) defined over customer behavioral events and attributes. These segments are used for hundreds of use-cases across Amazon and subsidiaries: automatically applying promotions to customer orders during checkout, blocking irrelevant advertisements, and personalizing the customer experience across Amazon websites, apps, and devices — even the words spoken by Alexa!

Our growing team owns a critically available (99.99% uptime) low-latency (<40ms) and high-volume (> 1 million requests per second) web-service which supports updates segment membership in real-time in as customers take actions (e.g. make a purchase, subscribe to Amazon prime, etc.). Our real-time updates ensure the most responsive and relevant experience possible for Amazon customers. At the same time, we coral large pools of historical customer behavioral data to ensure efficiency.

We need software engineers to help unlock new new use-cases for Amazon businesses and consumers, ensure the privacy of customers, and invent the next generation of world-class segmentation and targeting software.

Key job responsibilities
Software engineers design, build and support targeting software features. The Customer Segmentation team has a strong ownership model where every engineer takes the lead one or more projects at a time. We lead all parts of the project lifecycle:

- brainstorming / conception
- clarifying customer-facing and technical requirements
- designing software
- building, testing, and deploying
- providing support and debugging of live systems

In addition, our engineers are dedicated to building the best team possible. Engineers are partnered with consultants for project work and mentors/mentees for career development. Within months, new engineers are giving back, supporting new other members, and building a rewarding place to work.

About the team
Customer Segmentation supports hundreds of Amazon and subsidiary internal teams with their consumer-facing features. We partner with teams across the spectrum including: Website Personalization, Promotions, Payments, Music, Prime Video, Whole Foods, Audible, features for Businesses customers and Underserved Populations. The scale at which we operate provides opportunity for big impact. And the breadth of experiences we support provides exciting visibility into the ever changing world of Amazon.

Our technical strengths focus around (1) operating a scalable, highly available web-service and (2) large-scale data processing. Our signature service is a critical dependency for some checkout workflows on the Amazon website and we operate dozens of data pipelines, processing >100TB of data daily. Our engineers are frequently solving scaling and efficiency challenges, designing distributed-systems, and inventing process improvements and new features to guarantee continued availability in the months ahead.
