Software Engineer, Server (Ecommerce)

Irvine, CA
& Online Products is home to 400+ caring and passionate engineers, product managers, designers, and QA focused on the legendary gaming network,, that brings millions of gamers together and makes our products available to our players around the world. currently has multiple server engineering roles available on our Ecommerce Group.  The Ecommerce Group is about 130 collaborative team members, delivering the largest 1st party Ecommerce Platform in the gaming industry.  We have over 500 APIs, powering systems such as our Catalog Service which describes all of our games and in-game products that you can buy, our Entitlement Service which stores billions of records of ownership, our Order Service, which orchestrates our purchases, and various other systems, such as our payment gateways, keys, virtual currency wallet service, and more.  We also build advanced capabilities on top of our core platform, such as our viewership incentives system, which injects entitlements based on YouTube and Twitch viewership, and integrate with various 3rd party channels, such as Internet Game Rooms, external shops, and more.  It's an immense operation.

We primarily use Java and the Spring Framework, with a microservices architectural approach, SQL and NoSQL data stores, and public cloud technologies, to deliver a world-class Ecommerce Platform.  We spend a lot of time building new features and services, as well as modernizing some of our older services into small horizontally scalable microservices in public cloud.  We are an internal technology hub and are involved in some fashion with nearly every game release within Activision and Blizzard!

Our server engineers don't deliver just your simple APIs.  We work together to solve problems of scalability, performance, security, fault tolerance, reliability, observability, transactional safety and other distributed systems problems, multiple interconnected data centers globally, but we also aim towards simplicity, good modeling, and API design, maintainability, and more.  We have multiple zerg rush events per year, where our servers light up with 100x the load.  We are constantly improving and applying best practice observability to tune and monitor and measure our critical systems.

We pull in security experts to consult on various projects, such as the cryptography around our keys systems.  These are just a few examples of the server engineering projects we work on together.

We are a medium-sized team, which is a sweet spot for a great work environment, that supports lots of learning and cooperation. We are not too large, where you may work on a tiny sliver of layers and layers of home-grown tech, and we are not too small, where there is minimal support, but we are just the right size, for some good impact with a trusting and supportive community feel on the team.  Our team is warm and welcoming, and we take pride and celebrate the work that we launch for our players, together.

Covid-19 Hiring Update: We have transitioned to a work-from-home model and we are continuing to interview and hire during this time. This role is expected to begin as a remote position.  We understand each person’s circumstances may be unique and will work with you to explore possible interim options.  Eventually, most of our positions will be in Irvine, CA, or Austin, TX, and we will discuss this during the hiring process.
